This book was released on 2020-07-01 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a reference book for advanced graduate students and research engineers in shale gas development or rock mechanical engineering. Globally, there is widespread interest in exploiting shale gas resources to meet rising energy demands, maintain energy security and stability in supply and reduce dependence on higher carbon sources of energy, namely coal and oil. However, extracting shale gas is a resource intensive process and is dependent on the geological and geomechanical characteristics of the source rocks, making the development of certain formations uneconomic using current technologies. Therefore, evaluation of the physical and mechanical properties of shale, together with technological advancements, is critical in verifying the economic viability of such formation. Accurate geomechanical information about the rock and its variation through the shale is important since stresses along the wellbore can control fracture initiation and frac development. In addition, hydraulic fracturing has been widely employed to enhance the production of oil and gas from underground reservoirs. Hydraulic fracturing is a complex operation in which the fluid is pumped at a high pressure into a selected section of the wellbore. The interaction between the hydraulic fractures and natural fractures is the key to fracturing effectiveness prediction and high gas development. The development and growth of a hydraulic fracture through the natural fracture systems of shale is probably more complex than can be described here, but may be somewhat predictable if the fracture system and the development of stresses can be explained. As a result, comprehensive shale geomechanical experiments, physical modeling experiment and numerical investigations should be conducted to reveal the fracturing mechanical behaviors of shale.

This book was released on 2015 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Shale gas is one kind of the unconventional resources which is becoming an ever increasing component to secure the natural gas supply in U.S. Different from conventional hydrocarbon formations, shale gas reservoirs (SGRs) present numerous challenges to modeling and understanding due to complex pore structure, ultra-low permeability, and multiple transport mechanisms. In this study, the deviation against conventional gas flow have been detected in the lab experiments for gas flow through nano membranes. Based on the experimental results, a new apparent permeability expression is proposed with considering viscous flow, Knudsen diffusion, and slip flow. The gas flow mechanisms of gas flow in the SGRs have been studied using well test method with considering multiple flow mechanisms including desorption, diffusive flow, Darcy flow and stress-sensitivity. Type curves were plotted and different flow regimes were identified. Sensitivity analysis of adsorption and fracturing parameters on gas production performance have been analyzed. Then, numerical simulation study have been conducted for the SGRs with considering multiple mechanisms, including viscous flow, Knudsen diffusion, Klinkenberg effect, pore radius change, gas desorption, and gas viscosity change. Results show that adsorption and gas viscosity change will have a great impact on gas production. At last, the numerical simulation model for SGRs with multi-stage hydraulic fracturing horizontal well has been constructed. Sensitivity analysis for reservoir and fracturing parameters on gas production performance have been conducted. Results show that hydraulic fracture parameters are more sensitive compared with reservoir parameters. The study in this project can contribute to the understanding and simulation of SGRs"--Abstract, page iv.

Available in PDF, EPUB and Kindle. Book excerpt: With the recent progress in technologies such as hydraulic fracturing and horizontal drilling, unconventional resource development has exploded in recent years. Nevertheless, significant challenges remain for shale reservoirs because of the extensive number of uncertainties. Without proper characterization processes, extracting economic values from these projects will be difficult, and optimizations for future plans will also be challenging. Therefore, efficient models in production mechanism, management and optimization have gradually become hot topics among the petroleum industry. This study aims to address various crucial challenges during the production process of shale reservoirs, including unconventional well gas oil ratio (GOR) characterization, choke management, and well spacing optimization. Due to the ultra-low permeability and porosity, the fluid phase behavior in shale reservoirs significantly differs from the conventional fluid behavior and increases the production forecasting complexity. A substantial effort to better understand the mechanism is to characterize the unconventional well GOR, which always plays as a critical indicator to help predict long-term oil/gas production trends and develop appropriate production strategies. In this research, GOR behavior was first evaluated by a set of comprehensive sensitivity studies in a tight oil well model, which helped to investigate the key drivers that can impact the GOR response in unconventional resources. Then, a parent-child well-set case in Eagle Ford was presented. Through detailed characterization of the producing GOR, an improved understanding of the parent-child well behavior and the fracture hit impact can be obtained. In order to improve the efficiency of field operation, seeking for proper operation plan has been the focusing topic among the oil and gas industry. Choke management strategy selection is one of the essential measures to regulate fluid flow and control downstream system pressure, which could significantly impact the well production rate and estimated ultimate recovery (EUR). In this study, we utilized the non-intrusive embedded discrete fracture model (EDFM) method to handle complicated fracture designs and predicted the long-term EUR from conservative to aggressive choke strategy. Meanwhile, a series of sensitivity studies were presented to evaluate the impacts of various factors on shale gas production, including fracture permeability modulus, fracture closure level, and natural fractures network. The model becomes a valuable stencil to design fracture closure and complex fracture networks, which is a significant improvement for a more reliable choke management model in unconventional area. Another crucial part for well performance improvement is well spacing optimization. Consistent estimates of well spacing help reduce the impact of complex uncertainties from unconventional reservoirs, thereby improving the EUR and enhancing economic growth. We demonstrated a case study on well spacing optimization in a shale gas reservoir located in the Sichuan Basin in China. By using the advanced EDFM technology, complex natural fractures can be effectively captured and simulated. In this study, five different well spacing scenarios ranging from 300 m to 500 m were simulated individually to find the optimum well spacing that maximizes the economic revenue. As the practicability and the convenience showed in this workflow, it becomes feasible to be utilized in any other shale gas well

This book was released on 2018-12-17 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic fracturing is essential technology for the development of unconventional resources such as tight gas. So far, there are no numerical tools which can optimize the whole process from geological modeling, hydraulic fracturing until production simulation with the same 3D model with consideration of the thermo-hydro-mechanical coupling. In this dissertation, a workflow and a numerical tool chain were developed for design and optimization of multistage hydraulic fracturing in horizontal well regarding a maximum productivity of the tight gas wellbore. After the verification a full 3D reservoir model is generated based on a real tight gas field in the North German Basin. Through analysis of simulation results, a new calculation formula of FCD was proposed, which takes the proppant position and concentration into account and can predict the gas production rate more accurately. However, not only FCD but also proppant distribution and hydraulic connection of stimulated fractures to the well, geological structure and the interaction between fractures are determinant for the gas production volume. Through analysis the numerical results of sensitivity analysis and optimization variations, there is no unique criterion to determine the optimal number and spacing of the fractures, it should be analyzed firstly in detail to the actual situation and decided then from case to case.
