Abstract:

In many areas, expert knowledge is usually associated to a few number of specialists. Big companies, such as the petroleum companies, naturally employ a lot of specialists. However, the knowledge of these specialists are not fully availble to support the whole company at the same time. The software MAICE is a tool which can be used to model and keep expert knowledge. Being storaged, the expert knowledge can be used in order to provide expertise and support operational decisions, without requiring the specialist presence since it represents the specialist opinion. The tool may be applied in various areas like medicine, logistics and many engineering applications. It was originally developed as partnership with Petrobras (2007-2011), and its first applications refers to artificial lift methods. The objective of this work is to present some examples of MAICE applictions and also presenting this software as a tool to be applied in a general context of Oil&Gas.

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.

Biography:

Artyom Chemodanov graduated from Chemical Institute of Kazan Federal University in 2009.He is a junior research scientist at the Institute of Geology and Oil and Gas Technologies of Kazan Federal University. His research interests lay in the area of geochemical modeling of heavy oil fields for improving its development. His recent research shows that geochemical models of oil field allow assessment of location and direction of steam chamber movement using the measurements of some heavy oil biomarkers during the development of heavy oil fields by SAGD method.

Abstract:

Statement of the Problem: All heavy oil reservoirs under development in Tatarstan are presented by sands and heterogeneous, with respect to geology and, thus, the conformance of steam in the reservoir is not uniform.  The purpose of this study is to detect lateral and vertical gradients of relative concentrations of biomarkers presented in oil, which allows assessing potential drainage zones in the reservoir during the reservoir production by steam injection. In this research new method for monitoring of steam chamber development in 3D model was developed and tested.

Methodology & Theoretical Orientation: Total hydrocarbon fraction was isolated from core extracts and analyzed by GCMS method (TIC) for detection of various biomarkers and assessment of lateral and vertical gradients of their concentration in lateral.

Findings: It was found that the proportion of 4- and 1-methyldibenzothiophenes (MDBT) changes in lateral and in vertical directions. These changes are caused by biodegradation of organic matter. Laboratory research shows that 1-MDBT/4-MDBT ratio in native reservoir rocks is stable under high temperatures and pressure, so it can be measured in the samples of oil produced by SAGD method. This measurement will allow assessment of location and direction of steam chamber propagation.

Conclusion & Significance: In recent work the authors have developed geochemical model which can be used for assessment of oil flow directions during the development of heavy oil fields by SAGD method

Liu Hailong, male, an engineer of  the China Petroleum Exploration and Development Research Institute in SINOPEC, engaging in reservoir engineering and numerical simulation research, and graduated from the China Petroleum Exploration and Development Research Institute

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.

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.

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.

Title: Research on Well Type and Well Pattern Optimization for Tight Gas Recovery Enhancement
Speaker
Biography:

Dewei Meng began his professional career at RIPED in 2008, having abundant experience in unconventional gas development nearly 10 years. 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.
