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.
