Book excerpt: In the past decade, the rapid increase in the production of fossil energy has been made possible by effective reservoir stimulation and enhanced oil recovery (EOR) technologies for unconventional oil and gas reservoirs. As one of the most important reservoir stimulation technologies, hydraulic fracturing aims to increase the contact area between the target formation and production well. Such stimulation technologies usually involve complex fluid-solid coupling processes, including fracture initiation, fracture propagation, and fracture conductivity, etc. Enhanced oil recovery has been used to solve the problem of oil rate declining sharply after a period of production. In this process, some special chemicals will be injected into the reservoir to increase the recovery effectiveness of the residual oil. EOR processes often involve complex physical-chemical processes, including liquid emulsification, water-rock reactions, etc. Therefore, the progress of reservoir stimulation and EOR technology will contribute to the rapid development of unconventional oil and gas resources. Meanwhile, these technologies are also used in the development of geothermal and coal resources.

Book Synopsis Phase Behavior and Compositional Simulation of Solvent EOR Processes in Unconventional Reservoirs by : Sajjad Sadeghi Neshat
Download or read book Phase Behavior and Compositional Simulation of Solvent EOR Processes in Unconventional Reservoirs written by Sajjad Sadeghi Neshat and published by . This book was released on 2020 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in hydraulic fracturing and horizontal drilling technologies applied to unconventional resources have enabled very large increases in oil and gas production in the United States. While the initial production rate from new wells is often high, the rate of decline during the first year of production is also very high. The ultimate hydrocarbon recovery using current technology is estimated to be between 5 to 10%, which is very low compared to conventional oil reservoirs. These challenges have increased the demand for enhanced oil recovery (EOR) in unconventional reservoirs. Unconventional reservoirs have very different properties than conventional reservoirs such as extremely low permeability, wide and complex pore size distributions, high total organic carbon (TOC), and high heterogeneity. New cost effective EOR methods consistent with these properties are needed. This research presents a new framework for phase behavior modeling and compositional simulation of solvent EOR in unconventional reservoirs (also called tight oil reservoirs). Several new physical models were developed for this purpose. The new developments include a three-phase capillary pressure model, a phase stability method for multi-component mixtures with capillary pressure, coupled three-phase flash and capillary pressure models, and a new oil characterization method for organic-rich reservoirs. These models improve petrophysical, thermodynamic, and transport modeling of unconventional reservoirs. All new models were implemented in UTCOMP, an equation-of-state compositional reservoir simulator. The simulator was used for design and optimization of solvent EOR processes in organic-rich tight oil reservoirs. The oil recovery using cyclic huff-n-puff injection of a variety of solvents such as natural gas, CO2, methanol and dimethyl ether (DME) was compared. DME has the best performance among all solvents considered in this research. At reservoir conditions, DME mixes with both water and hydrocarbon phases. This helps to remove water blockage as well as retrograde condensate in gas-condensate reservoirs. DME can also extract part of the bitumen in the rock, which does not flow by itself due to its extremely high viscosity. Since the recovery rate of DME is very high, it can be recycled and injected back into the reservoir to reduce its net cost

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

Book Synopsis Technology and Economics Affecting Unconventional Reservoir Development by : Cecilia P. Flores Campero
Download or read book Technology and Economics Affecting Unconventional Reservoir Development written by Cecilia P. Flores Campero and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Worldwide, unconventional resources are important sources of oil and gas when most conventional resources are declining and demand for hydrocarbons is growing. The Masters? (1979) concept of the energy resource triangle suggest that the exploitation of unconventional reservoirs is particularly sensitive to both technology and commodity price parameters. In the United States, production from unconventional reservoirs has been stimulated by a combination of Federal tax credits, technical development programs -supported by government agencies and private organizations- and high commodity prices. In this work, the effect of technology and different economic events for selected unconventional oil and gas plays in the United States was evaluated according to the concept of the Resource Triangle Theory (RTT). Studies conducted in the Austin Chalk -our textbook case- and other seven unconventional plays in the United States have supported the RTT concept that high prices and better technologies do result in more drilling activity and more oil and gas production from unconventional reservoirs. For instance, two approaches were employed to support RTT concept: Correlation study and Forecasting graphs. On the first one, correlations of commodity prices and technology with drilling activity demonstrated that periods of high commodity prices coincide with increase in unconventional producing wells approximately 75% from selected plays in this study. The second one shows that high prices and technological advances also translate into additional oil and gas production and reserves. This behavior was observed through the analysis of a series of decline production curves using a VBA program in Excel that compute oil and gas production volumes and their corresponding economic values under specific conditions. The results indicated that maximum value of approximately $50 billion oil plus gas would have been possible using conventional hydraulic fracturing technology only. Moreover, subsequent episodes of high commodity allow the introduction of new technologies that have boosted even more oil and gas production from the plays. Great examples are the use of horizontal and multilateral wells which has opened up additional areas for development, such as the Barnett Shale and the Bakken Shale. Using horizontal wells has also revived older plays, such as the Austin Chalk. The combination of horizontal well technology and water fracturing technology has led to a dramatic increase in the development of both oil and gas from shale reservoirs. Current production schemes suggest that the plays could produce an additional of $320 billion when producing at rates higher than 5 BOE/day. Our results confirm the concept of the resource triangle that natural gas and oil resources can be produced from low quality resources when either product prices increase or when better technology is available. The seven oil and gas plays studied in this research are demonstrative examples.
