Abstract:

Unconventional shale reservoirs play an enormous role in hydrocarbon production in the United States. Among the shale gas producing plays, Marcellus shale has a growing contribution due to advances in horizontal drilling and hydraulic fracturing techniques. Even though the advances in these technologies have unlocked the gas contained in Marcellus shale, the quantification of the petrophysical properties remain challenging due to complex nature of the shale. Reliable values of the shale petrophysical properties including permeability and porosity are necessary for accurate estimation of the original gas-in-place, prediction of the production rates, and optimization of the hydraulic fracturing treatments. Unsteady state methods have been extensively used to estimate permeability of the shale samples because the shales typically have permeability values in Nano-Darcy range. However, the permeability values by determined by these techniques have been found often to have large margin of uncertainty which are attributed to the lack of consistent experimental protocols and the interpretations issues.

Abstract:

Statement of the Problem: Developing countries play an increasingly important role in the world energy markets, with their consumption of energy increasing significantly over the past two decades. According to a report released by the United States Energy Information Administration (EIA, 2013) these countries will account for 65 per cent of the world’s energy consumption by the year 2040. The increase has been particularly pronounced among the developing countries of East and Southeast Asia and is expected to continue into the next century. The increasing importance of the share of developing economies in the global energy markets also means there will be excessive increase in energy consumption which posed obstacles to economic development. The present paper aims to identify the key economic forces driving changes that influence energy demand.

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:

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.

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.

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.
