Abstract:

In Turkey, natural gas was first introduced in 1986. Following that, the use of natural gas has become rapidly widespread and started to be used for electricity generation, residential heating and industry, together with the increasing energy needs resulting from the rapid economic and population growth. Especially in the last 15 years, Turkey has become one of the leading countries with fastest-growing natural gas demand. Over the last 30 years, Turkey’s annual natural gas consumption growth rate is 18 percent, tripling its total energy consumption growth rate in the same period. However, it comes with a burden. The decision of increasing the use of natural gas in Turkey makes it highly import dependent, 99 percent, decreasing the level of security of supply. Hence, Turkish natural gas consumption has already reached to 46,35 Bcm as of the end of 2016 in Turkey, doubling the 2003 levels, representing 30 percent of Turkey’s primary energy consumption. However, Turkey was not successful in establishing a liberal natural gas market. Turkish Petroleum Pipeline Corporation (BOTAÅž) is responsible for almost 80 percent of the natural gas imports, much higher compared to private sector’s share. In addition, it subsides the gas prices, preventing the formation of a competitive market. Requiring a fundamental transformation of the natural gas market, Turkey is in the process of restructuring and liberalization.  Therefore, during this process, it is important to reveal the insights from the private sector players in the Turkish Natural Gas Market related to the successful formation and implementation of a sustainable, fully competitive, and liberal natural gas market. Consequently, the primary aim of this study is to gain insight into the private sector’s view related to the restructuring process of Turkish Natural Gas market, through a qualitative inquiry, including an industry-wide survey and a SWOT analysis. This study reveals the internal and external factors, the degree of importance of these factors for the future of the industry, and the level of consistency between these assessments.

He mainly engaged in development and evaluation of low permeability & tight gas reservoir and has made great contributions to improving reservoir engineering. He has published more than 10 papers in reputed journals.

Abstract:

Tight gas, the first large-scale used unconventional natural gas, has been extremely important in Chinese energy domain. According to statistics in 2015, proven geological reserve of tight gas accounts for more than 30% in that of nature gas. Meanwhile its production accounts for 25% of nature gas output. Under such circumstances, tight gas development mainly faces three kinds of challenges: firstly, newly built gas fields are needed for supplementation during field production decreasing; secondly, gas production ratio is largely affected by constant fluctuations of gas price and gradually decreased quality of newly developed reserves; thirdly, tight gas recovery needs to be enhanced dramatically since the general recovery factor is quite low, just around 35%. Therefore, how to guarantee stable development and enhance recovery factor of tight gas in a long run are the main problems during tight gas reservoir development. In this study Sulige gas field, the largest natural gas field in China, is taken for an example, mainly from well pattern optimization. Six specific aspects are taken in to account, and they are fine reservoir characterization, 3D geological modeling of complex reservoir, and distribution characteristics of remaining gas, well pattern infilling in developing area, recovery factor enhancement by horizontal wells and mixed well pattern. The results and methods are used for long-term and stable development in tight gas field.

Abstract:

Investigation of rock porosity and permeability is highly beneficial for geologists, petro-physicist and petroleum engineers in order to evaluate reservoir anisotropy, and its pore space geometry through the time and space. Clastic reservoir quality and classification could perform based on these data correlations. The Szolnok Formation in the great Hungarian plain is composed mainly of sandstones intercalated with marl and siltstones of delta fringe deposits. In the present study,    213 core samples were obtained from the Szolnok Formation and subjected for petrophysical investigations. Both horizontal and vertical permeability were measured with different techniques. Permeability anisotropy gives unambiguous diagnostic features for reservoir heterogeneity in case of siltstone- marl facies.   The study of grain size parameters and cross-plots constructed among measured reservoir properties indicate that Szolnok Formation has two main lithologic facies: 1. Clean sandstone (represented in this study by 141 samples) and 2.siltstone- marl (represented by 72 samples).  From the interpretation of measured data, it can obviously differentiate among good, intermediate and bad reservoir rocks in Szolnok Formation. Ultrasonic laboratory measurements were carried out for only 30 sandstone core samples. These samples were completely dry, while Sonic Viewer-120 instrument is used to measure seismic velocity, Poisson’s ratio and other mechanical properties such as rigidity, bulk modulus and Young’s modulus. Both Wyllie and Raymer equations were used to predict reservoir porosity in order to relate it to measured porosity. Effective pore radius is outlined from both porosity and permeability.

Abstract:

Naturally fractured reservoirs host more than 50% of the world remaining hydrocarbon reserves. Mechanism of fluid flow through such reservoirs is not well understood. This is mainly because, these reservoirs comprise of two mediums of diverse properties: rock matrix and fractures. In general the rock matrix acts as a source of fluid while the fractures serve as both the source and highly conductive flow paths. Fractures introduce high heterogeneity which affects fluid flow and mechanical stability. Effective development of these reservoirs and increase its fluid recovery requires a comprehensive understanding of fluid flow behaviour through a fracture -matrix system. The fluid flow characteristics of such reservoirs are strongly controlled by characteristic properties of fractures, which include density, distribution, orientation, and interconnectivity. Therefore, an accurate description and characterization of the fracture network is very important for flow simulation. Characterization of such reservoirs is extremely challenging due to (a) complex fracture geometry (b) lack of information on fracture properties. This results in a high level of uncertainty associated flow simulation.

The main purpose of this abstract is to employ innovative tools to characterize and evaluate the production potential of fractured basement reservoir. This will be achieved by developing an in-house hybrid fractured reservoir simulator using the generated fracture permeability tensor. This simulator depends on finite element method in poro-elastic environment.

Abstract:

Low permeability gas reservoir is an important type of gas reservoir on a global scale. At present, a large number of low permeability water bearing gas reservoirs have been found in the world. In China, there are more than 2×104m3 reserves distributed in this type reservoir. This kind of gas reservoir is mainly distributed in Sichuan and Ordos basin, China. This kind of gas reservoir is characterized by poor reservoir physical properties, strong heterogeneity, high water saturation, complex gas and water distribution, and no obvious gas-water contact. So, The primary problem to develop this type reservoir is how to optimize the favorable area. Because of the complex formation water distribution, it is very hard to optimize the enrichment area to develop this kind of gas reservoir. Based on the two characteristics of storage and permeability, and combing with the static and dynamic characteristics of the reservoir, it is an effective way to solve this problem that the reservoir is divided into different types of reservoir. Gaoqiao gas reservoir is located in the Ordos basin, and belongs to the low permeability water bearing gas reservoir. Take the Gaoqiao as an example, the classification criteria of storage permeability bodies are established and the type of drilled wells is classified. Based on the understanding of gas reservoir characteristics, the plane distribution of storage permeability body is drawn.  Based on this distribution, we can optimize the development area in Gaoqiao. This method can be used to optimize the development area to develop such reserves. Furthermore, this method is helpful for the effective development of a large number of these gas reservoirs in China and the world.

Yizhang Li (1991~), male, nationality of PRC, graduated from Tianjin University in 2013 and is now studying as a doctor candidate in China University of Petroleum, Beijing. He majors in material science and engineering and focuses on characterizing oil shale with optical measurement. 

Abstract:

Oil shale is widely viewed as important supplementary resource for petroleum. The quality of oil shale from certain region is conventionally assessed with maximum oil yield by Fischer Assay while the results may be different due to specific pyrolysis conditions. To determine utmost oil yield using non-chemical method is free from reaction interference and time-saving. In this study, we applied different combinations of pyrolysis temperature, heating rate and ventilating rate to process pulverized oil shale from Longkou, China so as to reserve various amount of organic matter. During pyrolysis, covalent bonds within kerogen of oil shale were subject to damage and thus shale oil and gas with light molecular weight formed. However, pyrolysis temperature was not sufficient to change inorganic mineral matrix. Therefore, the remaining organic matter of semicoke was distinct while the mineral matrix was alike. All of semicoke was compacted under same conditions to meet requirement of following optical experiments. Terahertz time domain spectroscopy was employed to detect semicoke tablets. According to the absorption of semicoke to terahertz wave, it was found that the transition of yield-condition dependence was in consistent with absorption-condition dependence. We’d analyzed influence of pyrolysis temperature, heating rate and ventilating rate to Fischer Assay. Briefly, it turned out that rise of pyrolysis spanning from 400 °C to 550 °C facilitate shale oil production. Besides, optimal values were found for both heating rate as well as ventilating rate at 15 °C/min and 0.6 L/min, respectively. Such a transition for oil yield was related to secondary cracking, which was verified by data on pyrolysis products. As organic matter own distinct response to terahertz wave, the artificial maturation process can be characterized with optical parameter in terahertz range. And this feature allows for the chance that optimization of pyrolysis efficiency based on terahertz time domain spectroscopy.

Abstract:

Abstract Based on the nonlinear percolation theory, a new nonlinear seepage model of low-permeability reservoir was established and an ideal three-phase and three-dimensional numerical reservoir simulation model for the multistage fractured horizontal well was built. By taking the impacts of pressure-sensitive effect and the threshold pressure gradient into consideration, the quasi-linear numerical model, Darcy numerical model and the non-Darcy numerical model were conducted. Meanwhile, the effects of parameters were fully investigated. The study shows that compared to the results of Darcy model, when taking nonlinear flow into consideration, the result shows higher energy consumption, lower pressure level, smaller liquid production, and slower water cut rising rate. When the injected fluid reaches the wellbore, the flowing bottom hole pressure increases quickly. However, the time of water front reaching the wellbore is different. Hence, when using non-Darcy flow expression, the process can be present precisely. The recovery ratio is positive with the starting pressure gradient of the water phase, but negative with the oil phase. With pressure-sensitive coefficient decreasing, recovery ratio increases quickly. If producing pressure differential is maintained at a proper value, then the effect of the pressure-sensitive coefficient on the permeability is reduced. With the threshold pressure gradient becoming smaller, the recovery ratio becomes higher.

Dhruvin Kaneria is an Oil and Gas innovator, graduating in Petroleum engineering from Pandit Deendayal Petroleum University. Just within 2 years he has presented more than 5 papers in various universities in India. His ongoing research includes Cambay Shale geomechanics, Proppant conductivity and on new ideas like Internet of things and Laser technology which could possibly change oil and operations.

Abstract:

The Cambay Basin is an intracratonic basin located along the western continental passive margin of Indian platform of Western Indian State of Gujarat. It has been prognosticated as the main shale gas reservoirs with resource potential of around 231 BCF/mi², high organic matter content (3.0%), complex lithology- stratigraphy and anisotropy. It is very difficult to understand the mineral assemblage, zone of weakness, fracture alignment and stress orientation in this unconventional reserve. The tectonic block chosen for investigation is Ahmedabad-Mehsana Tectonic Block (North Cambay Basin) of Cambay Basin, India. In the study, a directional dependence of the velocity of seismic waves (P and S Waves) in the horizontal and vertical core plugs of Cambay shale has been studied at different confining pressure (i.e. from 250 psi to 3000 psi) to understand the preferential orientation of mineral, microcracks, fracture alignment across the bedding plane and porosity. The elastic stiffness constants and Thomsen's parameters are calculated and plotted against the different confining pressure on both the plugs. The variation of velocities indicates the anisotropic nature of this shale and the same has been validated by the results of Single Stage Triaxial Geomechanical Test. In the second part of the study, rock mechanical properties like Young's modulus, Bulk Modulus and Poisson's ratio (both static and dynamic) has been determined and compared with the existing well logs of the block. The idea is to correlate and validate the log derived rock parameters with the core data from laboratory which will help in transforming and presenting the complex anisotropic nature of this shale in a simple way. This study can be utilized to provide the useful information on shale stimulation practices like hydraulic fracturing, micro seismic monitoring etc. All the results are coded in a Java Script and a simulator has been designed for correlation and validation of all the computed data.

Xinyang Miao is a PhD candidate in material science and engineering at China University of petroleum (Beijing) in the People’s Republic of China. His main research interest is oil and gas optics, including rock physics and application of terahertz technology.

Abstract:

Oil shale, a finely grained sedimentary rock with kerogen contained, has been gradually developed in China since the 1920s. Numerous oil and gas products as fuels and raw materials in petrochemical industries can be yielded by pyrogenation of kerogen. Generally, shales as well as oil shales are often highly anisotropic owing to various combined effects. Ultrasonic measurements have demonstrated that the elastic properties are isotropic in the directions parallel to the bedding, while anisotropic in other directions. Owing to the unique advantages, Terahertz (THz) technique has been applied in various research areas of oil and gas exploration recently, including exploration and development of oil and gas reservoirs, transportation of oil-gas as well as evaluation of petrochemicals and pollutants. Meanwhile, THz technique has also been employed to study the anisotropic response of materials. In this paper, THz technique was employed to investigate anisotropic response of oil shales from Longkou, Yaojie and Barkol with different oil yield. All the samples had significant anisotropy of refractive index (n) and absorption coefficient (α) with symmetries at the location of 180°, which were corresponded with the bedding plane and the partial alignment of particles. Besides, the D-values of experiment n in the vertical and parallel direction of the bedding plane were calculated as Δn’= n_^-n_‖, and samples from Beipiao and Huadian were also tested in the horizontal and vertical directions for a sufficient number of THz parameters.  Linear regression was built between the Δn’ of the samples from five regions and the oil yield, described as y=60.86x+3.72 for oil yield (y) and Δn’ (x), with the correlation coefficient R equaled 0.9866 and the residual sum of squares was 1.182, indicating THz technology could be an effective selection for evaluating the oil yield in oil shales from different regions.

Abstract:

Foaming and solvent degradation is a major issue in natural gas sweetening unit. Currently, GASCO Company (Abu Dhabi) is using aqueous methyldiethanolamine (MDEA) to scrub H₂S/CO₂.  Adsorption is mostly applied technology to regenerate MDEA. Polymeric/clay hybrid composite were used in continuous adsorption to remove contaminants using different column diameter and height. This study focusses on the removal of organic acid anions as major contaminant present in lean MDEA. Dimensional analysis has been carried out in order to identify the relevant dimensionless groups involved to provide scale up studies. The adsorption column bed diameter and bed height was changed from 1.5-2.6 cm and 10-45 cm, respectively. The columns with 2.6 cm diameter having 10, 23 and 45 cm height was filled with different weight of adsorbents. It was observed that with increasing bed diameter the breakthrough as well as bed saturation time was increased. The breakthrough curve for lower diameter column was observed to have a sharp slope and shortened mass transfer zone. The bed height of 10 cm had faster breakthrough as compared to 23 and 45 cm bed height. Thus, higher the bed height, higher is the breakthrough as more amount of lean MDEA can be treated.

B.Sc. and M.S degrees from Jordan University of Science and Technology, Ph.D degree from Stuttgart University/Germany. Research areas are: oxyfuel combustion, pyrolysis and char combustion, emission control technologies (NOx, SOx, PM), and others.

Abstract:

Direct combustion of Jordanian oil shale under oxyfuel conditions was investigated. Unstaged and staged air-firing as well as combustion at 27% O2/73% CO2 (OF27) was conducted successfully. A 20 kW vertical reactor was used at a combustion temperature of 1200â—¦C. Oil shale- N conversion rate to NO is higher during unstaged air-firing than oxyfuel combustion; they are 27% and 15% for air-firing and OF27 combustion, respectively. NOx emission reduced efficiently by adopting staged combustion technology under oxy-fuel conditions as well as air-firing. In addition, the reduction of simulated recycled NO has been investigated. The actual situation has been simulated by injecting NO in the reactor through the burner during OF27 combustion. The reduction of the injected NO is more efficient with staging compared to unstaged combustion mode; 100% reduction of the injected NO during staged OF27 combustion is registered while for unstaged OF27 combustion it ranges from 57% to 65%. The high sulphur content in Jordanian oil shale is considered one of the biggest challenges for its utilization. The oil shale- S conversion rates to SO2 is lower during unstaged OF27 combustion compared to air-firing; they are 69% and 49% for air-firing and OF27 combustion, respectively. For both unstaged combustion modes, direct limestone injection at different molar Ca/S ratios has been investigated; SO2 emissions are reduced significantly by direct limestone injection. At Ca/S molar ratio of 3, the desulphurization efficiencies are 100% and 95% for OF27 combustion and air-firing, respectively.

Abstract:

After more than ten years of tight gas development practice and technical research, China has successfully solved the technical problems of tight gas development, and it has become the most important contributor to China's natural gas production. Due to the strong heterogeneity of the tight gas reservoir, reserves producing degree and recovery rate is low, it needs more fine geological guidance to solve these problems, so the reservoir characterization of tight gas is crucial. This paper takes the Sulige gas field (the largest gas field in china) as a case study, because of its low abundance and strong heterogeneity, it is challenging for large scale commercial development of this field. Therefore, it is necessary to study the basic characteristics of effective reservoir, and first of all, looking for sweet spots is currently the priority.

Abstract:

Performance of CO₂ and hydrocarbon (HC) gas injection into a heavy crude oil was investigated at high pressure/temperature condition, using high permeable well-sorted original reservoir sandstone. Complete series of PVT and slime tube tests were followed by vertical and horizontal gas floods to study the impact of injection rate, injectant type and reservoir pressure. Dimensional analysis was performed to study the involved mechanism and forces. Sometimes direct injection of CO₂ may not be practically and economically possible. In addition, in plans for CO₂ storage, CO₂ as a free phase in a reservoir is coupled with a significant leakage risk that prevents the scenario of direct injection. Therefore, in the second part, the enhancement of heavy oil recovery was tested by the carbonated water injection.

Abstract:

Three types of adsorbents: Bentonite clay Silica gels, Charcoal were selected to evaluate their behavior in minimizing sulfur contents in diesel fuel, and to characterize the more efficient adsorbent. Native diesel fuel with sulfur contents of 0.8% was received in a temperature range between (250-320oC) from fractional distillation of crude oil obtained from field of Kirkuk / Iraq with sulfur contents of 2% was used in this work. Desulfurization was performed in a continuous circulation of 150 ml. of diesel fuel through a glass column (2 cm. id x 25 cm length) containing 100 gm. adsorbent by circulating pump. Adsorption for sulphur contents was investigated at different duration of times i.e. 2hr, 4hrs and 6 hrs. Bentonite exhibited the maximum desulphurization yield of 65 % at 6 hrs adsorption. Surface areas of all adsorbents were characterized by SEM and EDX analysis. The FT-IR study of the desulphurized diesel sample revealed that mostly high molecular weight thioles and thiophenic compounds were depleted during adsorption process.

Abstract:

            The upper Yangtze region has experienced multi geological events, and there is characteristic of high evolution and strong transformation of the marine shale. So that the shale gas accumulation is very complex. By the comparison of North American and the upper Yangtze shale, Longmaxi formation organic rich shale of the Upper Yangtze Region is older, higher degree of evolution, but the sedimentary environment and lithology basically is the same as North American Barnett shale. Due to Longmaxi shale experienced multi deformation and different burial environment, its hydrocarbon has entered the over-mature stage. North American tectonic is relatively stable and its shale is still in the middle- high mature stage. The upper Yangtze shale gas accumulation and preservation are controlled by the reservoir pore pressure and the sealing of the accumulation unit. Combined the Longmaxi shale reservoir and the stratigraphy deformation characteristics of the upper Yangtze region, the shale gas sweet is controlled by deep shelf anoxic face and structure transformation and adjustment zone. Recently, all of the found Longmaxi shale gas reservoirs locate in gentle wings and axis of residual syncline of the zone. And a series of identification technologies of the shale gas reservoir and prediction technologies of sweet distribution have been summed in the upper Yangtze region. Longmaxi shale gas layer takes it as a feature : high gamma, high acoustic time difference, low P-wave and S -wave velocity ratio, and with high resistance, low density, low compensation neutron anomaly. The Longmaxi sweet layer appears" low frequency wave impedance reflection and AVO anomalies".  The structure transformation and adjustment zone shows the multi-source convergence and natural net-fracture reservoir conditions, therefore good accumulation units of syncline belts become shale gas high production in the upper Yangtze region marine. Therefore Longmaxi shale gas sweet is controlled by deep shelf anoxic face and tectonic transformation and adjustment zone in the upper Yangtze region.

Abstract:

Volatile organic compounds (VOCs) emanated from car spills and oil and gas development can have mutagenic and carcinogenic effects on human beings. Adsorption using activated carbon with high specific surface area and large pore volume was one of the most widely used and mature methods to recycle VOCs. In this paper, an investigation was presented about terahertz time-domain spectroscopy (THz-TDS) as a novel tool for the characterization of the dynamic adsorption rate of volatile organic compounds, including isooctane, ethanol, and butyl acetate, in the pores of active carbon. The THz-TDS peak intensity (E_P) was extracted and corresponded to the measurement time frames. By analyzing E_P with time, the entire process could be divided into three physical parts including volatilization, adsorption and stabilization so that the adsorption dynamics could be clearly identified. In addition, based on the pseudo-second-order kinetic model and the relationship between E_P and time in the adsorption process, a mathematical model was built in terms of the adsorbed rate parameter and the THz parameter. Consequently, the adsorption rate of isooctane, ethanol, and butyl acetate could be assessed by the THz measurement, indicating that THz spectroscopy could be used as a promising selection tool to monitor the adsorption dynamics and evaluate adsorption efficiency in the recovery of pollutants.

Yan Song has her expertise in the evaluation and characterization of fluid (microfluidic) flow in the oil and gas field based on new optical method. Her research of oil-water two phase flow based on terahertz time-domain spectroscopy makes supplement of flow pattern analysis in the oil and gas field. 

Abstract:

Understanding the dynamics behaviors of oil-water two phase flow is crucial to important problems in the oil wells and pipelines. Because of the extremely high sensitivity of terahertz wave to hydrogen bonding, a new method to study oil-water two phase flows is put forward to study oil-water two phase flows using the terahertz time-domain spectroscopy (THz-TDS). By comparing the amplitudes of the maximum peak in THz-TDS, the ability of THz-TDS has been shown previously to discriminate the flow pattern for oil-water two phase flow with low water content in rectangular pipe. For further study on oil-water two phase flow, we conduct another experiment using diesel and tap water. the amplitude of THz-TDS of oil-water two phase flow is corresponding to the flow pattern, the flow pattern and the critical flow rate can be distinguished by THz-TDS. When the oil-water mixture flow rates are high, the water phase is intensively impacted by the oil phase, and W/O flow is found and the water content in the test part almost keeps unchanged in this situation, resulting the unchanged THz signal in the measurement. As the decrease of mixture flow rate, the droplets are mainly affected by gravity and the forces associated with the motion reduces. For further decrease in the mixture flow velocities, the number of droplets reduces and the maximum drop size increases, the flow is gravity dominated and then the O & DW/O flow pattern is formed. In order to investigate the effect of the input mixture flow rate on the slip, simulations have been performed under selected mixture flow rates for the two-phase flows with different input water fractions here. The results reveal that the slip is mainly dominated by the mixing flow rate at low flow rates, whereas the effect decreases gradually with increasing flow rate.

Abstract:

For ensuring casing and cementing quality, mud cake removal is essential. Various problems like stuck pipe take place because of the presence of mud cake. Mechanical methods of water jetting and chemical methods by means of acids, oxidizers, chelating agents and enzymes are currently employed for mud cake removal. However, water jetting can cause water blockage problems. Also, Mud cakes of different permeability will be removed unevenly by same intensity water jets. Acids and oxidizers are very reactive but non- specific species, imposing several post perforation problems and formation damage.

As an alternative, we propose a new method/device in this study with the usage of nanobots and laser grinding. The nanobots, placed in carrier, can be sent through drill string into the drill bit from where they can be deployed in all directions into the targeted zone. These non-adherent and self-propelled nanobots will move through the vertical permeability of the mud filtrate and would interpret the petro physical properties of the mud filtrate.

Abstract:

Foaming and solvent degradation is a major issue in natural gas sweetening unit. Currently, GASCO Company (Abu Dhabi) is using aqueous methyl diethanolamine (MDEA) to scrub H₂S/CO₂. Adsorption is mostly applied technology to regenerate MDEA. Polymeric/clay hybrid composite were used in continuous adsorption to remove contaminants using different column diameter and height. This study focusses on the removal of organic acid anions as major contaminant present in lean MDEA. Dimensional analysis has been carried out in order to identify the relevant dimensionless groups involved to provide scale up studies. The adsorption column bed diameter and bed height was changed from 1.5-2.6 cm and 10-45 cm, respectively. The columns with 2.6 cm diameter having 10, 23 and 45 cm height were filled with different weight of adsorbents. It was observed that with increasing bed diameter the breakthrough as well as bed saturation time was increased. The breakthrough curve for lower diameter column was observed to have a sharp slope and shortened mass transfer zone. The bed height of 10 cm had faster breakthrough as compared to 23 and 45 cm bed height. Thus, higher the bed height, higher is the breakthrough as more amount of lean MDEA can be treated. Thomas and Yoon-Nelson models were used for analyzing the experimental data. For the scale up studies, the concentration of the contaminants in the column was approximated into two zones: A large saturated zone and a smaller unused zone. Then assumptions were made for laboratory to pilot scale that when the column gets longer, the size of the saturated zone will change but the size of the unused zone remain constant. While, for industrial scale both the zones will increase accordingly. The findings of this research could contribute to the industrial scale up for the purification of lean MDEA.

Leema Abd Al-Rahman Al-Makhadmeh is currently working as an Associate Professor at the Department of Environmental Engineering, Al-Hussein Bin Talal University and Department of Chemical Engineering, Jordan University of Science and Technology, Jordan. She has completed her BSc and MS degrees from Jordan University of Science and Technology and PhD degree from Stuttgart University, Germany. Her research areas are oxy-fuel combustion, pyrolysis and char combustion, emission control technologies (NOx, SOx, PM) and others.

Abstract:

Direct combustion of Jordanian oil shale under oxy-fuel conditions was investigated. Unstaged and staged air-firing as well as combustion at 27% O₂/73% CO₂ (OF27) was conducted successfully. A 20 kW vertical reactor was used at a combustion temperature of 1200 ^oC. Oil shale-N conversion rate to NO is higher during unstaged air-firing than oxy-fuel combustion; they are 27% and 15% for air-firing and OF27 combustion, respectively. NOx emission reduced efficiently by adopting staged combustion technology under oxy-fuel conditions as well as air-firing. In addition, the reduction of simulated recycled NO has been investigated. The actual situation has been simulated by injecting NO in the reactor through the burner during OF27 combustion. The reduction of the injected NO is more efficient with staging compared to unstaged combustion mode; 100% reduction of the injected NO during staged OF27 combustion is registered while for unstaged OF27 combustion it ranges from 57% to 65%. The high sulfur content in Jordanian oil shale is considered one of the biggest challenges for its utilization. The oil shale-S conversion rate to SO₂ is lower during unstaged OF27 combustion compared to air-firing; they are 69% and 49% for air-firing and OF27 combustion, respectively. For both unstaged combustion modes, direct limestone injection at different molar Ca/S ratios has been investigated; SO₂ emissions are reduced significantly by direct limestone injection. At Ca/S molar ratio of 3, the desulfurization efficiencies are 100% and 95% for OF27 combustion and air-firing, respectively.

Abstract:

Volatile organic compounds (VOCs) emanated from car spills and oil and gas development can have mutagenic and carcinogenic effects on human beings. Adsorption using activated carbon with high specific surface area and large pore volume was one of the most widely used and mature methods to recycle VOCs. In this paper, an investigation was presented about terahertz time-domain spectroscopy (THz-TDS) as a novel tool for the characterization of the dynamic adsorption rate of volatile organic compounds, including isooctane, ethanol, and butyl acetate, in the pores of active carbon. The THz-TDS peak intensity (E_P) was extracted and corresponded to the measurement time frames. By analyzing E_P with time, the entire process could be divided into three physical parts including volatilization, adsorption and stabilization so that the adsorption dynamics could be clearly identified. In addition, based on the pseudo-second-order kinetic model and the relationship between E_P and time in the adsorption process, a mathematical model was built in terms of the adsorbed rate parameter and the THz parameter. Consequently, the adsorption rate of isooctane, ethanol and butyl acetate could be assessed by the THz measurement, indicating that THz spectroscopy could be used as a promising selection tool to monitor the adsorption dynamics and evaluate adsorption efficiency in the recovery of pollutants.

Abstract:

Oil shale is widely viewed as important supplementary resource for petroleum. The quality of oil shale from certain region is conventionally assessed with maximum oil yield by Fischer Assay while the results may be different due to specific pyrolysis conditions. To determine utmost oil yield using non-chemical method is free from reaction interference and time-saving. In this study, we applied different combinations of pyrolysis temperature, heating rate and ventilating rate to process pulverized oil shale from Longkou, China so as to reserve various amount of organic matter. During pyrolysis, covalent bonds within kerogen of oil shale were subject to damage and thus shale oil and gas with light molecular weight formed. However, pyrolysis temperature was not sufficient to change inorganic mineral matrix. Therefore, the remaining organic matter of semicoke was distinct while the mineral matrix was alike. All of semicoke was compacted under same conditions to meet requirement of following optical experiments. Terahertz time domain spectroscopy was employed to detect semicoke tablets. According to the absorption of semicoke to terahertz wave, it was found that the transition of yield-condition dependence was in consistent with absorption-condition dependence. We had analyzed influence of pyrolysis temperature, heating rate and ventilating rate to Fischer Assay. Briefly, it turned out that rise of pyrolysis spanning from 400 °C to 550 °C facilitate shale oil production. Besides, optimal values were found for both heating rate as well as ventilating rate at 15 °C/min and 0.6 L/min, respectively. Such a transition for oil yield was related to secondary cracking, which was verified by data on pyrolysis products. As organic matter own distinct response to terahertz wave, the artificial maturation process can be characterized with optical parameter in terahertz range and this feature allows for the chance that optimization of pyrolysis efficiency based on terahertz time domain spectroscopy.

Yan Song has her expertise in the evaluation and characterization of fluid (microfluidic) flow in the oil and gas field based on new optical method. Her research of oil-water two-phase flow based on terahertz time-domain spectroscopy makes supplement of flow pattern analysis in the oil and gas field.

Abstract:

Understanding the dynamics behaviors of oil-water two-phase flow is crucial to important problems in the oil wells and pipelines. Because of the extremely high sensitivity of terahertz wave to hydrogen bonding, a new method to study oil-water two-phase flow is put forward using the terahertz time-domain spectroscopy (THz-TDS). By comparing the amplitudes of the maximum peak in THz-TDS, the ability of THz-TDS has been shown previously to discriminate the flow pattern for oil-water two-phase flow with low water content in rectangular pipe. For further study on oil-water two-phase flow, we conduct another experiment using diesel and tap water. The amplitude of THz-TDS of oil-water two-phase flow is corresponding to the flow pattern, the flow pattern and the critical flow rate can be distinguished by THz-TDS. When the oil-water mixture flow rates are high, the water phase is intensively impacted by the oil phase and W/O flow is found and the water content in the test part almost keeps unchanged in this situation resulting in the unchanged THz signal in the measurement. As the decrease of mixture flow rate, the droplets are mainly affected by gravity and the force associated with the motion reduces. For further decrease in the mixture flow velocities, the number of droplets reduces and the maximum drop size increases, the flow is gravity dominated and then the O & DW/O flow pattern is formed. In order to investigate the effect of the input mixture flow rate on the slip, simulations have been performed under selected mixture flow rates for the two-phase flows with different input water fractions. The results reveal that the slip is mainly dominated by the mixing flow rate at low flow rates, whereas the effect decreases gradually with increasing flow rate.

Dhruvin Kaneria is an Oil and Gas innovator, graduating in Petroleum Engineering from Pandit Deendayal Petroleum University. He has presented more than 5 papers in various universities in India. His ongoing research includes Cambay Shale geomechanics, proppant conductivity and on new ideas like Internet of things and laser technology which could possibly change oil and operations.

Abstract:

The Cambay Basin is an intracratonic basin located along the western continental passive margin of Indian platform of Western Indian State of Gujarat. It has been prognosticated as the main shale gas reservoirs with resource potential of around 231 BCF/mi², high organic matter content (3.0%), complex lithology-stratigraphy and anisotropy. It is very difficult to understand the mineral assemblage, zone of weakness, fracture alignment and stress orientation in this unconventional reserve. The tectonic block chosen for investigation is Ahmedabad-Mehsana Tectonic Block (North Cambay Basin) of Cambay Basin, India. In the study, a directional dependence of the velocity of seismic waves (P and S waves) in the horizontal and vertical core plugs of Cambay Shale has been studied at different confining pressure (i.e., from 250 psi to 3000 psi) to understand the preferential orientation of mineral, microcracks, fracture alignment across the bedding plane and porosity. The elastic stiffness constants and Thomsen's parameters are calculated and plotted against the different confining pressure on both the plugs. The variation of velocities indicates the anisotropic nature of this shale and the same has been validated by the results of Single Stage Triaxial Geomechanical Test.

It is spread out in the Deepwater Tano and West Cape Three Points blocks. The field covers 110 km², which is about the size of 155 football pitches. The Tweneboa field (6 km east of Jubilee) was discovered in March 2009. In July 2010 the Owo-1 drilling confirmed the reasonably big amounts of the field. A maximum depth of 4,000 meters has been drilled. There does not seem to be an underwater channel connection between the Tweneboa and the Jubilee field. Apart from these major findings, there are also several smaller wells close by. In particular the Owo-1 well in the Tweneboa field and the small Dana GH Western Tano field are located very close to the Côte d’Ivoire border. For these drillings precise locations have not been made public, but all the exact coordinates of the Jubilee wells have been published and it seems clear that they are within Ghanaian territory [Ghanaweb.com, 2010(I)] The Jubilee Field the figures of the amount of oil expected in the Jubilee field, published by Ghanaian newspapers, vary between 1 and 2 billion barrels of crude oil. In their status report 2008, the state owned Ghana National Petroleum Company (GNPC) published figures stating that 800 million barrels of oil is the total field amount, with an upside potential of 3 billion barrels of oil [GNPC, 2008].

Abstract:

Sichuan Basin is the basin with the largest number of proven gas reserves, the number of gas fields found and the cumulative output of gas in China. The study of basement structure of the basin is very important in the deep oil and gas exploration. The research concerned on the structure of Sichuan basin’s basement based on aeromagnetic data. We improved the method of determining the residual magnetization direction by the maximum cross-correlation method based on the vertical gradient and the total gradient of the magnetic anomaly. This reduction to the pole (RTP) method of magnetic anomalies considering the residual magnetization direction makes the result more reliable. We obtained residual basement magnetic anomaly (RBMA) from aeromagnetic data, then inverted the undulating magnetic basement and its susceptibility distribution, divided the magnetic basement of Sichuan Basin into 7 parts and discussed the controlling effect of Sichuan basin’s magnetic basement on oil and gas migration and accumulation. Besides, the basement faults system was patterned with the help of the directional derivative, vertical derivative and horizontal gradient of the RBMA. The magnetic basement obtained in this paper is the top interface of lower mesoproterozoic with a depth of 3~10 km, which reflects the tectonic morphology and undulating characteristics of the deep metamorphic crystalline basement in the basin. The large inherited paleo-uplift developed on the magnetic basement uplift provides the conditions for the formation and aggregation of the pre-Cenozoic oil and gas.

Abstract:

Investigation of rock porosity and permeability is highly beneficial for geologists, petro-physicist and petroleum engineers in order to evaluate reservoir anisotropy and its pore space geometry through the time and space. Clastic reservoir quality and classification could perform based on these data correlations. The Szolnok Formation in the great Hungarian plain is composed mainly of sandstones intercalated with marl and siltstones of delta fringe deposits. In the present study, 213 core samples were obtained from the Szolnok Formation and subjected for petrophysical investigations. Both horizontal and vertical permeability were measured with different techniques. Permeability anisotropy gives unambiguous diagnostic features for reservoir heterogeneity in case of siltstone marl facies. The study of grain size parameters and cross-plots constructed among measured reservoir properties indicate that Szolnok Formation has two main lithologic facies: Clean sandstone (represented in this study by 141 samples) and siltstone marl (represented by 72 samples). From the interpretation of measured data, it can obviously differentiate among good, intermediate and bad reservoir rocks in Szolnok Formation. Ultrasonic laboratory measurements were carried out for only 30 sandstone core samples. These samples were completely dry, while Sonic Viewer-120 instrument is used to measure seismic velocity, Poisson’s ratio and other mechanical properties such as rigidity, bulk modulus and Young’s modulus. Both Wyllie and Raymer equations were used to predict reservoir porosity in order to relate it to measured porosity. Effective pore radius is outlined from both porosity and permeability.

Behzad Rostami (Corresponding Author) is an associate Professor of petroleum engineering in the Institute of Petroleum Engineering (IPE) at University of Tehran. His research interests involve gas injection based methods of enhanced oil recovery, foam injection and carbonated water injection, CO₂ sequestration in Saline aquifers and depleted hydrocarbon reservoirs, gravity drainage and multi block interaction in fractured media. Rostami has authored more than 40 technical papers in international journals and also supervised more than 30 graduate students. 

Abstract:

Performance of CO₂ and hydrocarbon (HC) gas injection into a heavy crude oil was investigated at high pressure/temperature condition, using high permeable well-sorted original reservoir sandstone. Complete series of PVT and slime tube tests were followed by vertical and horizontal gas floods to study the impact of injection rate, injectant type and reservoir pressure. Dimensional analysis was performed to study the involved mechanism and forces. Sometimes direct injection of CO₂ may not be practically and economically possible. In addition, in plans for CO₂ storage, CO₂ as a free phase in a reservoir is coupled with a significant leakage risk that prevents the scenario of direct injection. Therefore, in the second part, the enhancement of heavy oil recovery was tested by the carbonated water injection. The results of the first part of core flooding experiments demonstrated that gravity and solubility are the most effective mechanisms in oil recovery. The reduction in oil recovery in horizontal flooding for HC gas injection is higher due to the smaller difference between the densities of CO₂ and oil compared to HC gas/oil systems. Furthermore, a small increase of oil recovery after breakthrough (BT) during N₂ injection proves the importance of the solubility mechanism. Therefore, In this case, more precised analysis could be performed by applying the dissolution number instead of Capillary and/or Bond number.

Abstract:

In Turkey, natural gas was first introduced in 1986. Following that, the use of natural gas has become rapidly widespread and started to be used for electricity generation, residential heating and industry, together with the increasing energy needs resulting from the rapid economic and population growth. Especially in the last 15 years, Turkey has become one of the leading countries with fastest-growing natural gas demand. Over the last 30 years, Turkey’s annual natural gas consumption growth rate is 18%, tripling its total energy consumption growth rate in the same period. However, it comes with a burden. The decision of increasing the use of natural gas in Turkey makes it highly import dependent, 99%, decreasing the level of security of supply. Hence, Turkish natural gas consumption has already reached to 4635 bcm as of the end of 2016 in Turkey, doubling the 2003 levels, representing 30% of Turkey’s primary energy consumption. However, Turkey was not successful in establishing a liberal natural gas market. Turkish Petroleum Pipeline Corporation (BOTAS) is responsible for almost 80% of the natural gas imports, much higher compared to private sector’s share.

Abstract:

Tight gas, the first large-scale used unconventional natural gas has been extremely important in Chinese energy domain. According to statistics in 2015, proven geological reserve of tight gas accounts for more than 30% in that of nature gas. Meanwhile its production accounts for 25% of nature gas output. Under such circumstances, tight gas development mainly faces three kinds of challenges: Firstly, newly built gas fields are needed for supplementation during field production decreasing; secondly, gas production ratio is largely affected by constant fluctuations of gas price and gradually decreased quality of newly developed reserves; thirdly, tight gas recovery needs to be enhanced dramatically since the general recovery factor is quite low, just around 35%. Therefore, how to guarantee stable development and enhance recovery factor of tight gas in a long run are the main problems during tight gas reservoir development. In this study, Sulige gas field, the largest natural gas field in China, is taken for an example, mainly from well pattern optimization. Six specific aspects are taken in to account and they are fine reservoir characterization, 3D geological modeling of complex reservoir and distribution characteristics of remaining gas, well pattern infilling in developing area, recovery factor enhancement by horizontal wells and mixed well pattern. The results and methods are used for long-term and stable development in tight gas field.

Abstract:

After more than ten years of tight gas development practice and technical research, China has successfully solved the technical problems of tight gas development, and it has become the most important contributor to China's natural gas production. Due to the strong heterogeneity of the tight gas reservoir, reserves producing degree and recovery rate is low, it needs more fine geological guidance to solve these problems, so the reservoir characterization of tight gas is crucial. This paper takes the Sulige gas field (the largest gas field in china) as a case study, because of its low abundance and strong heterogeneity, it is challenging for large scale commercial development of this field. Therefore, it is necessary to study the basic characteristics of effective reservoir and first of all, looking for sweet spots is currently the priority. Comprehensive geological study confirmed that the reservoirs with coarse grain, high content of quartz are more easily lead to dissolution which is the most constructive diagenesis in Sulige gas field and the dissolved pores are almost the basis of high quality reservoirs. So the sweet spots are located in the coarse grained sand bodies with high content quartz and these sand bodies are mainly distributed in the lower part of the channel deposits and channel bar deposits. Now the answer is obvious, predicting channels especially the main river channels distribution is the key to search for sweet spots. Through seismic and geological study, first set up the typical log and seismic response characteristics of different types of sands, then carry out sedimentary facies, diagenesis, reservoir evaluation study and so on, finally simulate the channel development. On the base of the geological models, we can predict the sweet spots distribution. This technology has been applied in many blocks of Sulige gas field, the proportion of higher effective wells drilled in the past 5 years increased by a big margin.

Abstract:

Low permeability gas reservoir is an important type of gas reservoir on a global scale. At present, a large number of low permeability water bearing gas reservoirs have been found in the world. In China, there are more than 2×10⁴ m³ reserves distributed in this type reservoir. This kind of gas reservoir is mainly distributed in Sichuan and Ordos basin, China. This kind of gas reservoir is characterized by poor reservoir physical properties, strong heterogeneity, high water saturation, complex gas and water distribution and no obvious gas-water contact. So, the primary problem to develop this type reservoir is how to optimize the favorable area. Because of the complex formation water distribution, it is very hard to optimize the enrichment area to develop this kind of gas reservoir. Based on the two characteristics of storage and permeability and combing with the static and dynamic characteristics of the reservoir, it is an effective way to solve this problem that the reservoir is divided into different types. Gaoqiao gas reservoir is located in the Ordos basin and belongs to the low permeability water bearing gas reservoir. Take the Gaoqiao as an example, the classification criteria of storage permeability bodies are established and the type of drilled wells is classified. Based on the understanding of gas reservoir characteristics, the plane distribution of storage permeability body is drawn. Based on this distribution, we can optimize the development area in Gaoqiao. This method can be used to optimize the development area to develop such reserves. Furthermore, this method is helpful for the effective development of a large number of these gas reservoirs in China and the world.

Abstract:

Three types of adsorbents: Bentonite clay, silica gels, charcoal were selected to evaluate their behavior in minimizing sulfur contents in diesel fuel and to characterize the more efficient adsorbent. Native diesel fuel with sulfur contents of 0.8% was received in a temperature range between (250-320 ^oC) from fractional distillation of crude oil obtained from field of Kirkuk/Iraq with sulfur contents of 2% was used in this work. Desulfurization was performed in a continuous circulation of 150 ml of diesel fuel through a glass column (2 cm. i.d. × 25 cm length) containing 100 gm adsorbent by circulating pump. Adsorption for sulfur contents was investigated at different duration of times i.e., 2 hours, 4 hours and 6 hours. Bentonite exhibited the maximum desulphurization yield of 65% at 6 hours adsorption. Surface areas of all adsorbents were characterized by SEM and EDX analysis. The FT-IR study of the desulphurized diesel sample revealed that mostly high molecular weight thioles and thiophenic compounds were depleted during adsorption process.

Abstract:

Oil shale, a finely grained sedimentary rock with kerogen contained, has been gradually developed in China since the 1920s. Numerous oil and gas products as fuels and raw materials in petrochemical industries can be yielded by pyrogenation of kerogen. Generally, shales as well as oil shales are often highly anisotropic owing to various combined effects. Ultrasonic measurements have demonstrated that the elastic properties are isotropic in the directions parallel to the bedding, while anisotropic in other directions. Owing to the unique advantages, Terahertz (THz) technique has been applied in various research areas of oil and gas exploration recently, including exploration and development of oil and gas reservoirs, transportation of oil-gas as well as evaluation of petrochemicals and pollutants. Meanwhile, THz technique has also been employed to study the anisotropic response of materials. In this paper, THz technique was employed to investigate anisotropic response of oil shales from Longkou, Yaojie and Barkol with different oil yield. All the samples had significant anisotropy of refractive index (n) and absorption coefficient (α) with symmetries at the location of 180°, which were corresponded with the bedding plane and the partial alignment of particles. Besides, the D-values of experiment n in the vertical and parallel direction of the bedding plane were calculated as Δn’=n_^-n_‖, and samples from Beipiao and Huadian were also tested in the horizontal and vertical directions for a sufficient number of THz parameters. Linear regression was built between the Δn’ of the samples from five regions and the oil yield, described as y=60.86x+3.72 for oil yield (y) and Δn’ (x), with the correlation coefficient R equaled 0.9866 and the residual sum of squares was 1.182, indicating THz technology could be an effective selection for evaluating the oil yield in oil shales from different regions.

Abstract:

For ensuring casing and cementing quality, mud cake removal is essential. Various problems like stuck pipe take place because of the presence of mud cake. Mechanical methods of water jetting and chemical methods by means of acids, oxidizers, chelating agents and enzymes are currently employed for mud cake removal. However, water jetting can cause water blockage problems. Also, mud cakes of different permeability will be removed unevenly by same intensity water jets. Acids and oxidizers are very reactive but non-specific species, imposing several post perforation problems and formation damage. As an alternative, we propose a new method/device in this study with the usage of nanobots and laser grinding. The nanobots, placed in carrier, can be sent through drill string into the drill bit from where they can be deployed in all directions into the targeted zone. These non-adherent and self-propelled nanobots will move through the vertical permeability of the mud filtrate and would interpret the petro physical properties of the mud filtrate. The sensors would then send this data to molecular processor and with the help of radio frequency transmitter and receiver; we could immediately interpret the real time data from every point in the wellbore. This data would be used to change the intensity of the lasers in accordance with the petro physical properties. Lasers would then vaporize the mud cake according to its thickness and interpretation obtained and will grind the mud cake by creating popped holes. The precision and control over direction and power which laser provides could really be beneficial in mud cake removal and the same device could also be used for various other jobs like perforation and enhancing permeability during production phase. Nanotechnology integrated laser system holds great potential in removing mud cake efficiently and could significantly be useful in multilateral and horizontal wells.
