Abstract:

The objective of this work is the investigation of production possibility of high octane environmental ethanol gasoline blends based on Euro specifications. The environmental gasoline is the key to keep the environment safe and clean. Moreover, it aids in reducing gas emissions after combustion of gasoline. One of the main methods to produce the environmental gasoline is blending gasoline with oxygenated compounds such as ethanol. Ethanol is chosen among other oxygenated compounds as it has a high influence on physico-chemical characteristics of gasoline rather than other oxygenated compounds. In addition, it has a high octane number as well as it is not polluting the environment and clean additive. In the experimental study, the choice of environmental gasolines is based on Euro-3 specifications for samples without ethanol blend and Euro-5 specifications for samples with ethanol blend; after upgrading. Various blend stocks have been prepared which have reformate, isomerate, full refinery naphtha (FRN), heavy straight run naphtha (HSRN), hydrocracked naphtha, heavy hydrocracked naphtha, coker naphtha and heavy coker naphtha. In this study, ASTM standard methods are performed for spark ignition fuels to characterize its physical and chemical properties. The results show that one has exhibited the optimum specifications of Euro-3 and thus its physico-chemical characteristics are 755.11 kg/m³ of density, 55.88 of ^oAPI, 95 of RON, 88 of MON, 40% by volume of aromatic content and 0.66% by volume of benzene content. Moreover, ASTM distillation curve shows that the volume percentage at 150^oC is 83. At the same time, the final boiling point (FBP) and recovery volume percent are 198^oC and 96 respectively. While another sample has the poorest physical as well as chemical properties so that it is blended with ethanol to upgrade its characteristics. Therefore, the target is determining the optimum ethanol volume percent to be blended with poorest sample to yield the highest properties of gasoline. These blends are namely as E0, E5, E10, E15, E 20. The results indicate that E5 is the optimum one for Euro-5 specifications after upgrading and thus its physico-chemical characteristics are 745.55 kg/m³ of density, 58 of ^oAPI, 101 of RON, 98 of MON, 32.65% by volume of  aromatic content and 0.47% by volume of benzene content. Moreover, ASTM distillation curve illustrates that the volume percentage at 150^oC is 75. At the same time, the final boiling point (FBP) and recovery volume percent are 190^oC and 97 respectively. In addition, its Reid vapor pressure equals 8.1 psi and the heat of combustion equals 35 MJ/L. In the final, Blending gasoline with ethanol is an essential issue concerning the production of environmental gasolines.

Feng Yuelin is a PhD candidate from China University of Petroleum (East China), studying in the area of petroleum geology. 

Abstract:

The Shuangfeng area is located in the Linnan Sub-sag, Huimin Depression, Bohai Bay Basin, China. This area contains four oil-bearing series: lower Es3, middle Es3, upper Es3 and Es2. However, the reservoirs in Es3 formation are low permeability, resulting high cost exploitation. Reservoirs in upper formation (Es2) become focused. Depending on the braided delta facies in Es2, the reservoirs can be divided into three types: Distributary channel reservoir, under water distributors channel reservoir and mouth bar reservoir. On the basis of core observing from 28 wells and 62 samples, a regional study, involving thin section, scanning electron microscopy and mercury injection method, has been undertaken. The thin section results indicate that the clastic rocks of distributary channel reservoir are mainly lithic arkose and lithic sandstone. The major lithology of underwater distributary channel reservoir and mouth bar reservoir are feldspathic litharenite sandstone. All of them have good sorting and middle texture maturity. The scanning eletron microscopy result shows that there exist two types: macroporisity and microporosity. The mercury injection method figures up the physical property of the three reservoirs. The calculation of compacted rate shows that the three type reservoirs have the similar range. All the analysis show that:1) the main principal controlling factors in reservoir are sedimentation, the diagenesis and lithology have less influence; 2) in Shuangfeng area the mouth bar reservoir has better physical property than the other two types. The results make the controlling factors of reservoirs clear and will help the oil and gas exploration in the region.

Zhang Tianjiao is a PhD student from China University of Petroleum, East China, studying in the area of petroleum geology.

Abstract:

The Qingnan sub-sag is located within the Dongying Sag, Jiyang Depression, Bohai Bay Basin, on-shore China. This sub-sag was indicated as a promising exploration area, however, compared to the other sub-sags in the Dongying Sag, the characters and distribution characteristics of Qingnan sub-sag remain poorly understood which restricts the oil and gas exploration in this region. A regional study, involving core observation, well-logging, 3-D seismic, sporopollen, organic carbon content, characteristic elements and heavy mineral, has been undertaken. The fan delta, delta and beach bar were recognized based on 20 core observation and well-logging data. The paleogeomorphic shows stable shallow semi-enclosed sub-sag based on the 3-D seismic data covering the region, making the paleo-hydrodynamic power weak. The paleo-climate is humid and hot which is indentified by sporopollen fossil, including pinaceae, granodiscus and quercoidites. Two provenance systems were recognized based on the characteristic elements and heavy mineral. All the analysis show that: 1) the gentle paleogeomorphic is advantage of the development of fan delta, delta and beach bar; 2) the humid and hot paleo-climate provides accommodation space and protection for the clastic sedimentary of fan delta and delta; 3) the fan delta is controlled by the north provenance system, the delta is controlled by the south provenance system, beach bar is controlled by the both; 4) the weak power of paleo-hydrodynamic restrict the distribution range of beach bar.The results make the distribution regularity of sedimentary facies clear and will help the oil and gas exploration in the region.

Rasha Hosny Abd Elmawla has completed her PhD at the age of 32 years from Benha University and still postdoctoral studies at Egyptian Petroleum Research Institute (EPRI). 

Abstract:

In this paper we prepared mesoporous silica by simple single step method to separate oil (and gas) from produced water. Investigate the prepared mesoporous silica by XRD, FTIR, Raman, N₂ adsorption–desorption and TEM. Then a continuous fixed bed study was carried out using prepared mesoporous silica for oil removal from produced water. The effects of flow rate and bed height on the breakthrough characteristics of the adsorption system were determined. XRD analysis of the silica powder showed complete formation single phase mesoporous without contamination of other phases of silica. The maximum removal (70.26%) was achieved for a flow rate of 0.5mL/min and a bed height of 1.5 mm. Two models Thomas and Yoon–Nelson were applied to predict the breakthrough curves. The results show that Thomas model was fitted well the adsorption data with a correlation coefficient (R²) at different conditions. R² values suggested that the suitable model for describing the chemisorption oil on prepared mesoporous silica was Thomas model. The model showed that the prepared mesoporous silica was suitable adsorbent for oil using fixed bed adsorption.

Abstract:

The measurement of k_r (relative permeability) in carbonate rock is difficult and has great uncertainties due to the complex pore system such as dissolved pore, cavity and fractures. Several equations for the calculation of k_r are developed, but they assume single pore system that it cannot be applied directly to the complex pore system. Furthermore, the wetting characteristics have to be considered because most carbonate rocks tend to oil-wet. This study presents the method of k_r estimation with respect to the heterogeneous pore network. Firstly, the wetting characteristics are determined by the measurement of contact angle. For each core, pore size distribution, P_c (capillary pressure) and residual oil saturation are measured. From the estimated contact angle, all the samples are determined as an oil-wet. It is observed that P_c has different curve according to the macro and micro-pore, respectively. Then, k_r is generated from P_c by using Brook-Corey equation for each pore size. As a result, for the macro-pore, the water has higher kr than oil that it can be displaced easily by only the small reduction of oil saturation. In contract, the micro-pore has general shape of kr curve. Consequently, it is found that oil flows differently through macro and micro-pore according to the oil saturation

Donghyeon Kim received his BS from Chonbuk National University. Currently, he is MS student in Petroleum Engineering Lab. His experiment topic is sorption characteristic of various coal size by methane gas.        
 

Abstract:

In this study, adsorption and desorption characteristic were analyzed by changing the particle size of coal in order to estimate the CBM production potential. We used sub-bituminous coal samples from Kotabaru filed in Indonesia and volatile matter, ash and moisture content analyzed. All samples were crushed and they are divided into seven groups with particle size from 50mesh to 20 mm. For each sample, volumetric method was applied to measure the Langmuir pressure (PL), Langmuir volume (VL), and equilibrium time. From results, as particle size increases, Langmuir volume that is the maximum gas content of the sample decreases due to the reduction of specific surface area, but they show a little difference. In contrast, in desorption process, more time was needed for the large particle size to reach an equilibrium state because desorbed gas flow through the longer path and defuses by the concentration difference. In conclusion, desorption characteristics with coal size should be considered because the pore volume, pore size, and effective surface area are different. Moreover, Langmuir isotherm measurement for the lump coal considering cleat spacing is essential to obtain a more precise CBM production profile.

Abstract:

At present, a large number of low permeability water bearing gas reservoirs have been found in the world, and meanwhile, there are more than 2×10⁴m³ reserves distributed in this type reservoir 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. The primary problem to develop this type reservoir is how to optimize the building area. Because of the complex formation water distribution, the application effect of conventional optimize method is not good. Any reservoir is characterized by two aspects of storage and permeability. In this paper, according to the physical property and movable water, the reservoir is divided into six storage permeability bodies by using dynamic and static data.  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:

A series of moveable small scale skid-mounted liquefiers for scattered and isolated natural gas resources have been developed and tested, with liquefaction capacity of 10,000 Nm³/d, 15,000 Nm³/d, 30,000 Nm³/d, 60,000 Nm³/d and 100,000 Nm³/d. The compressor unit and cold box of liquefiers are compactly integrated in a skid. The liquefiers are based on a mixed-refrigerant liquefaction cycle with R22 pre-cooling. Most of the devices in liquefiers are easily available commercial refrigeration products. An oil-lubricated single-stage screw compressor is used for the compression of mixed-refrigerant, combined with air coolers. The core of cold box is an aluminum plate-fin heat exchanger with four flow passages. The liquefiers were tested and operated under different conditions. The minimum specific power consumption of 10,000 Nm³/d type was 0.54 kW h/Nm³, which was equivalent to 15.3% of the gas consumed with the rest liquefied. The power consumption of 30,000 Nm³/d type and 100,000 Nm³/d type were only 0.40 kW h/Nm³ (including all facilities) and 0.35 kW h/Nm³ respectively. This series of liquefiers could cover various liquefaction requirements such as small natural gas or coal-bed methane exploitations, distributed peak-shaving, and boil-off gas reliquefaction. A flexible distributed liquefaction center could be established with the combination of a set of small liquefiers.

Atif Zafar is a student of M.Sc Oil and Gas Engineering in school of Petroleum Engineering, China University of Petroleum (East China). His major is Reservoir Engineering. He is also a Lecturer at the Department of Petroleum Technology, University of Karachi, Pakistan.

Abstract:

An application of Integration of Well Test Analysis in reservoir characterization and field development is presented in this paper. The real data of Jin Gas Field of L-Basin of Pakistan is used.

The basic concept behind this work is to enlighten the importance of well test analysis in a broader way (i.e. reservoir characterization and field development) unlike to just determine the permeability and skin parameters. Normally in the case of reservoir characterization we rely on well test analysis to some extent but for field development plan, the well test analysis has become a forgotten tool specifically for locations of new development wells.

This paper describes the successful implementation of well test analysis in Jin Gas Field where the main uncertainties identified during initial stage of field development when location of new development well was marked only on the basis of G&G (Geologic and Geophysical) data. The seismic interpretation could not encountered the boundary (fault, sub-seismic fault, heterogeneity) near the main and only producing well of Jin Gas Field whereas the results of the model from the well test analysis played a very crucial rule in order to propose the location of second well of the newly discovered field.

The results from different methods of well test analysis of Jin Gas Field are also verified and supported by other tools of Reservoir Engineering i.e. Material Balance Method and Volumetric Method.

He is currently undertaking PhD ( Final year ) in Leeds University  – UK researching in” Analysis of the wear of the oil well drill bits” with Dr. Ali Hassanpour , Dr. Colin Hare and Prof. M. Ghadiri.

Abstract:

Predicting the wear of drill bits is essential for all oil and gas industries to maximise drilling efficiency and reduce loss in money and time. Typically, this problem has been handled by evaluating the specific energy of the drill bits at drilling formation intervals along with well logs and geophysical analysis. Although these techniques could provide good indication of the bit tooth wear, lack of consideration of material properties of rock and bit in the previous wear models, the bit balling phenomena and high level of vibration of the drill bit might give misleading results that affect the reliability of these techniques.

The present study focused on the determination of the wear of roller-cone bits taking into account the hardness of the rock formation and the materials forming the drill bit, along with other drilling parameters, such as rotary speed, rate of penetration, weight on bit and the time required to drill a specific interval.

The bit wear obtained from the formula developed in this work is compared to the qualitative in-situ bit tooth wear for various drilled formation intervals of a number of wells in the south of Iraq for which a close match is observed.

The new approach for bit wear determination could be used as a trending tool to evaluate the status of the drill bits or predicting the wear of roller-cone bits. The study could potentially be extended and applied to other types of drill bits such as Polycrystalline Diamond Compact (PDC) bits.

Abstract:

The Abu Shaybah Formation (ASF) ranges in age from Carnian to Norian (Late Triassic), and is exposed from the foothill slopes of the Tarhuna - Gharyan scarp stretching west wards to Ar Rabitah and Al Khums to the eastward along the Jabal Nafusah. The Lower boundary is sharp and unconformable with the Al Aziziyah Formation, (marine deposit) and the upper is locally unconformable with the Abu Ghaylan Formation (marine deposit). Seven sections have been measured in the study area and the maximum thickness of Abu Shaybah Fm. is about 254 m located in Wadi Ghan. It consists of gravely sandstone, coarse sandstone, silty clay and mainly mudstone facies in Abu Ghaylan Road section is about 21m thickness of this formation. Series of sandstone bodies, fining up ward cycles, from 8 to 12m thick of cycles in fluvial meandering and 20 to 25m thickness of fluvial braided cycles. Four main facies association can be characterized in ASF, Facies association 1) fluvial braided, channel deposit (CH). Extensive sandstone coarse to very coarse grained, pebbly scattered and character by graded trough cross stratification , up to 15m thick of channels with no clay content. Fcaies association 2) Fluvial meandering,  Its sandstone, medium to coarse grained highly argillaceous, trough cross stratification point bar deposit overlain by 3 to 5 m thick of shale, (over bank and crevasse splay deposits), and isolated sand bodies lateral accretion. Fcaies association 3) Flood Plain and over bank consist of red to green silty shale commonly mottled and content rootlet, up to 30m thickness in Wadi Ghan section and Facies association 4) It is a marine transitional zone. This sediment of ASF deposited under two strongly controlled by climate and tectonic with large sub-aerial accommodation space rather than increase in subsidence rate in the study area. Sequence startigraphic theory can be applied to these continental deposits, by defining base level and accommodation space, within the context of genetically related, coherent depositional sequences. Amalgamated multi-storey sand bodies are typical of Low stand conditions, isolated ribbon sand bodies typify transgressive conditions (sub-divided into early and late stages) and isolated multi-lateral sand bodies characterize High-stand conditions.

Dominic Adaoiza Onimowo has completed BEng degree in Mechanical Engineering and MSc graduate in Petroleum and Gas Engineering, who is currently undergoing his PhD at Anglia Ruskin University on Optimization of inflow control valves.

Abstract:

The influx of water and or gas into the wellbore is a problem which diminishes oil recovery, increases separation costs and drastically reduces well production life. The current solution to this problem is the use of an Autonomous Inflow Control Valve (AICV) developed through the EU FP7 project called REVIVAL. The valve works to prevent water and or gas breakthrough into the wellbore and only allow oil to flow into the wellbore by detecting viscosity differences amongst the fluids which create varied pressure drops used to control the valves opening or closing. The current research follows the same concept aims on optimisation and control of flow in the inflow control valve by considering various geometries and cases using computational fluid dynamics, CFD to discover more efficient ways to operate the valve. The cases selected are based on fluid flow, oil in particular through various conduits at various Reynolds numbers.  The cases are a straight pipe, a coil pipe, a swirl pipe, a slinky type coil and a coil with an internal coil. The results show that there is a significant increase in pressure drop with the new designs which means the opening and closing of the piston in the inflow control valve would be more efficient hence achieving better valve response. The results obtained from this investigation could be extended to other applications in fluid mixture separation.

Abstract:

This paper is the second part of a comprehensive research, its goal is to create a database about the existence of the NORM (Naturally Occurring Radioactive Material) in petroleum fields, terminals & gas export stations across Libya, the NORM was measured in two oil ports (Al-Hariqa Port Tobruk, east of the country, and Zawia Port, west of the country) where oil is exported there from, which is coming from two oilfields in which a relatively high proportion of radiation in scales’ samples was recorded (the first part of the research, which was presented in -RANC2016- Budapest) in order to try to track the spread of pollution resulting of the Scales’ NORM and make sure the possibility of arriving at the ports. From the results, it is clear that the NORM levels in oil ports and commercial ones are within the allowed limits (Exemption level). Samples were of 1.5 litres of water taken from the ports’ basins where the oil tankers are shipped in shipping oil ports at the shipping & discharge basins into the commercial ports. Gamma Ray which was emitted from the samples was measured by High pure Germanium Detector –HPGe at the Radiation Prevention Department in Tajura Nuclear Research Center-Tripoli, Libya.

Yuqing Liu is a PhD candidate from China University of Petroleum (East China), studying in the area of structural analysis of petroliferous basi006E.

Abstract:

The basins developed quite differently in the SCS, which was due to the complicated dynamic background. Based on the interpretion of high-accuracy seismic data, different structures of four basins from different continental margins were analyzed. The results showed that the faults in Yinggehai basin were mainly strike-slip, extensional strike-slip as well as extensional faults, and the evolution of the basin could be divided into three stages, including strike-slip extensional rifting stage, extensional strike-slip rifting stage and the stage of subsidence; two types of faults were formed in Pearl River Mouth Basin, including extensional and strike-slip extensional faults, and the basin experienced three stages, which were rifting, subsidence and tectonic activation; there were mainly extensional faults in Reed Basin, and the evolution could also be divided into three stages which were rifting, drifting and subsidence; both extensional faults and compression faults occurred in Taixinan Basin, and the evolution stages of the basin were rifting, compression inversion and subsidence. Combined with peripheral dynamic events in that period, the mechanism of the above differences of the basins in response to dynamic background was under discussion，which showed that plate interaction, deep mantle activities and large strike-slip faults were three key factors affecting basin development in different degree. This study can support the further geological researches on basins in the South China Sea and guide the exploration in oil and gas in this area.

Abstract:

The minimum miscibility pressure (MMP) is one of the most important parameter to be determined in miscible gas injection projects to ensure and maximize the displacement sweep efficiency inside the reservoir. Usually the most effective way of determining the MMP is to run slim tube experiments. However, in the early screening stage, we often relay on the published empirical correlations to estimate the MMP and identify the most suitable candidates for the EOR gas injection projects. Also reliable estimation of the MMP helps the operator to develop injection conditions and to plan suitable surface facilities. In this paper, our main aim objective was to examine different published empirical CO₂ MMP correlations using measured data mainly obtained from Libya and other published resources, and also to develop a new simple reliable correlation to be applied in the oil industry. The data collected covered a wide range of CO₂ MMP (1544–6244 psia) and oil API gravity (28-52ºAPI). Minitab regression tool was deeply used in our study and a wide range of new constructed correlations ranging from simple to complex ones were developed and statistically evaluated. Different PVT variables including P_b, T, API, g_g, R_si, molecular weight, volatile oil fraction, and intermediate oil fraction were considered in our study. The proposed simple CO₂ MMP correlation is mainly function of the measured P_b, API, T, and R_si and has very reliable degree of accuracy (SD=6.7%, RE =0.44%, AbsRE = 5.74%, R² =95.22%) for the examined data.  Also, this new correlation is more superior to all other industry published correlations that demonstrated an abs relative error ranges between 14.04% to 20.40% which are much higher percentage of error than our correlation and the standard deviation ranges between 14.67% to 29.52% which almost triple times of our correlation accuracy. The new correlation was validated against 100 measured PVT variables (P_b, R_si, T & API) obtained from Libya, and the predicted CO₂ MMP results have demonstrated very reliable trend (within the measured CO₂ MMP trend) with no anomalies. Introducing more variables such as mole fraction of the light components and the molecular weight of the C₇₊ to the simple proposed correlation will add minor improvement to the accuracy, which supports the emphasis on adopting the simple correlation.

Abstract:

Along with the improvement of equipment reliability, human error has become a great threat to the oil industry reliability and safety. Statistics show that human error is a major contributor to over 80% of accidents in chemical and petrochemical industries. Therefore, in order to ensure effective prevention of catastrophic accidents, the role of human in accident dynamics should be considered during risk assessment processes. The purpose of this study is to provide a method for estimating the instant and precise of human error probability (HEP) using cognitive reliability and error analysis method (CREAM) and Bayesian network. For this purpose, data related to dynamic context (or common performance conditions) was collected by a self-design questionnaire. Then, the gathered data was processed via MSBNx software. The results indicate that the highest HEP value is associated to the outside operators with 0.0912. In this study, factors such as unavailability of procedures/plans, multiple simultaneous goals, inadequacy of training and experience, and poor crew collaboration were identified as the common performance conditions that could effect on the HEP. Therefore, the method can be used as a useful and applicable tool to estimate the HEP value, in particularly in complex and uncertain systems such as oil industries.

Abstract:

The mud causes considerable pollution impacting several sectors, especially the groundwater system and the staff working on Drilling wells so as to mitigate the environmental effects of the sludge on the environment we propose two treatment processes (scenarios 1 and scenario 2) like: thermal desorption, stabilization/solidification off line), these treatments are very privileged and used in the field of treatment of oil muds, in (Hassi-Messaoud) Algeria.  We use the "life cycle analysis" to evaluate the environmental impacts of each process (the two scenarios),   the environmental impacts of each scenario are compared. Which are performed by the use of models of eco-indicator 99 by software “SIMAPRO7”. This evaluation allowed us to identify and quantify the contributions of emissions on human toxicity, the depletion of resources and the ecosystem quality, which are the main categories of impact in this specific Saharian context. The main substances of the assignment of the environment seem to be the chemicals added to the mud.  As regards the comparison of the two treatment scenarios, the thermal desorption  could be considered as the best method; it has the lowest impact in the three dominant categories scores, aside from the very large consumption of fossil energy causing from atmospheric emission.
