This book was released on 2015 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon dioxide enhanced oil recovery is not only an effective way to manage carbon dioxide emissions, but also a superior choice to achieve oil recovery. This thesis concentrates on CO2-EOR in an ultra-low permeability reservoir. Matrix permeability has been shown to be less than 0.001 md for most parts of the reservoir. Careful selection of modeling strategy, data collation and screening, enabled the construction of a dynamic model, which was adjusted through history matching of primary and waterflooding production phases, to analyze the potential of carbon dioxide enhanced oil recovery in this field. Although no capillary pressure data were provided, it was considered necessary to analyze the impact of capillary pressure on production forecasts. Production results indicate the existence of larger permeability channels. CO2-EOR offers multiple benefits for a long-term production and capillary pressure is advantageous to oil production.

This book was released on 2017-03-30 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the feasibility of CO2-EOR and sequestration in a mature Indian oil field, pursuing for the first time a cross-disciplinary approach that combines the results from reservoir modeling and flow simulation, rock physics modeling, geomechanics, and time-lapse (4D) seismic monitoring study. The key findings presented indicate that the field under study holds great potential for enhanced oil recovery (EOR) and subsequent CO2 storage. Experts around the globe argue that storing CO2 by means of enhanced oil recovery (EOR) could support climate change mitigation by reducing the amount of CO2 emissions in the atmosphere by ca. 20%. CO2-EOR and sequestration is a cutting-edge and emerging field of research in India, and there is an urgent need to assess Indian hydrocarbon reservoirs for the feasibility of CO2-EOR and storage. Combining the fundamentals of the technique with concrete examples, the book is essential reading for all researchers, students and oil & gas professionals who want to fully understand CO2-EOR and its geologic sequestration process in mature oil fields.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Teapot Dome field is located 35 miles north of Casper, Wyoming in Natrona County. This field has been selected by the U.S. Department of Energy to implement a field-size CO2 storage project. With a projected storage of 2.6 million tons of carbon dioxide a year under fully operational conditions in 2006, the multiple-partner Teapot Dome project could be one of the world's largest CO2 storage sites. CO2 injection has been used for decades to improve oil recovery from depleted hydrocarbon reservoirs. In the CO2 sequestration technique, the aim is to "co-optimize" CO2 storage and oil recovery. In order to achieve the goal of CO2 sequestration, this study uses reservoir simulation to predict the amount of CO2 that can be stored in the Tensleep Formation and the amount of oil that can be produced as a side benefit of CO2 injection. This research discusses the effects of using different reservoir fluid models from EOS regression and fracture permeability in dual porosity models on enhanced oil recovery and CO2 storage in the Tensleep Formation. Oil and gas production behavior obtained from the fluid models were completely different. Fully compositional and pseudo-miscible black oil fluid models were tested in a quarter of a five spot pattern. Compositional fluid model is more convenient for enhanced oil recovery evaluation. Detailed reservoir characterization was performed to represent the complex characteristics of the reservoir. A 3D black oil reservoir simulation model was used to evaluate the effects of fractures in reservoir fluids production. Single porosity simulation model results were compared with those from the dual porosity model. Based on the results obtained from each simulation model, it has been concluded that the pseudo-miscible model can not be used to represent the CO2 injection process in Teapot Dome. Dual porosity models with variable fracture permeability provided a better reproduction of oil and water rates in the highly fractured Tensleep Formation.

Download or read book The Reservoir Performance and Impact from Using Large volume Intermittent Anthropogenic CO2 for Enhanced Oil Recovery written by Stuart Hedrick Coleman and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic CO2 captured from a coal-fired power plant can be used for an enhanced oil recovery (EOR) operation while mitigating the atmospheric impact of CO2 emissions. Concern about climate change caused by CO2 emissions has increased the motivation to develop carbon capture and sequestration (CCS) projects to reduce the atmospheric impact of coal and other fossil fuel combustion. Enhanced oil recovery operations are typically constrained by the supply of CO2, so there is interest from oil producers to use large-volume anthropogenic (LVA) CO2 for tertiary oil production. The intermittency of LVA CO2 emissions creates an area of concern for both oil producers and electric utilities that may enter into a CO2 supply contract for EOR. An oil producer wants to know if intermittency from a non-standard source of CO2 will impact oil production from the large volume being captured. Since the electric utility must supply electricity on an as-needed basis, the CO2 emissions are inherently intermittent on a daily and seasonal basis. The electric utility needs to know if the intermittent supply of CO2 would reduce its value compared to CO2 delivered to the oil field at a constant rate. This research creates an experimental test scenario where one coal-fired power plant captures 90% of its CO2 emissions which is then delivered through a pipeline to an EOR operation. Using real emissions data from a coal-fired power plant and simplified data from an actual EOR reservoir, a series of reservoir simulations were done to address and analyze potential operational interference for an EOR operator injecting large-volume, intermittent CO2 characteristic of emissions from a coal-fired power plant. The test case simulations in this study show no significant impact to oil production from CO2 intermittency. Oil recovery, in terms of CO2 injection, is observed to be a function of the total pore volumes injected. The more CO2 that is injected, the more oil that is produced and the frequency or rate at which a given volume is injected does not impact net oil production. Anthropogenic CO2 sources can eliminate CO2 supply issues that constrain an EOR operation. By implementing this nearly unlimited supply of CO2, oil production should increase compared to smaller-volume or water-alternating-gas (WAG) injection strategies used today. Mobility ratio and reservoir heterogeneity have a considerable impact on oil recovery. Prediction of CO2 breakthrough at the production wells seems to be more accurate when derived from the mobility ratio between CO2 and reservoir oil. The degree of heterogeneity within the reservoir has a more direct impact on oil recovery and sweep efficiency over time. The volume of CO2 being injected can eventually invade lower permeability regions, reducing the impact of reservoir heterogeneity on oil recovery. This concept should mobilize a larger volume of oil than a conventional volume-limited or WAG injection strategy that may bypass or block these lower permeability regions. Besides oil recovery, a reservoir's performance in this study is defined by its CO2 injectivity over time. Elevated injection pressures associated with the large-volume CO2 source can substantially impact the ability for an oil reservoir to store LVA CO2. As CO2, a less viscous fluid, replaces produced oil and water, the average reservoir pressure slowly declines which improves injectivity. This gradual improvement in injectivity is mostly occupied by the increasing volume of recycled CO2. Sweep efficiency is critical towards minimizing the impact of CO2 recycling on reservoir storage potential. Deep, large, and permeable oil reservoirs are more capable of accepting LVA CO2, with less risk of fracturing the reservoir or overlying confining unit. The depth of the reservoir will directly dictate the injection pressure threshold in the oil reservoir as the fracture pressure increases with depth. If EOR operations are designed to sequester all the CO2 delivered to the field, additional injection capacity and design strategies are needed.

Download or read book A Simulation Study of Enhanced Oil Recovery Using Carbon Dioxide Foam in Heterogeneous Reservoirs written by Su Tham and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional gas flooding suffers from poor sweep efficiency in heterogeneous reservoirs. In absence of mobility control, gas preferentially travels through the path of least resistance, bypassing oil in low permeability areas. Stable foams restrict flow in high permeability channels, diverting flow to the lower permeability layers. This allows injected fluid to contact oil which would have been unswept by conventional gas flood. The objective of this research is to determine the extent of improvement caused by use of foam for CO2 floods in a range of heterogeneous reservoirs. Moreover, this study aims to provide a qualitative understanding of foam in heterogeneous reservoirs which would help in designing successful CO2 foam flooding in enhanced oil recovery projects. The simulation study involves 2D reservoir models with varying reservoir heterogeneity modeled by different Dykstra-Parsons coefficients and correlation lengths in the areal and vertical directions. A Surfactant-Alternating-Gas (SAG) scheme and a Water-Alternating-Gas (WAG) scheme were carried out to determine the improvement of using foam in SAG compared to conventional WAG. The CO2 breakthrough times, recovery factors, and sweep efficiencies based on pore volume injected are calculated from simulation results. The study showed that all three factors were improved across all heterogeneities when foam was present in the system.

This book was released on 2021 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon dioxide flooding in viscous oil systems has been proven to improve oil recovery and store CO2 in several geologic basins worldwide. With global energy steadily transitioning towards decarbonization, CO2-EOR and Sequestration can reduce the carbon footprint from crude oil production. Although well accepted globally, the potential of improved oil recovery and CO2 storage capacity has not been extensively studied in Alaska. Since the CO2 injection process involves phase transition, reservoir simulation becomes more complex. It requires reliable techniques to estimate the ultimate recovery factor, oil production rate, and CO2 storage volumes precisely. This study focuses on carbon dioxide enhanced oil recovery (CO2-EOR) and storage in the Orion satellite field of Alaska, its ability to reduce greenhouse gases, and the technical and economic feasibility of a CO2 flooding project. In this study, the Peng-Robinson equation of state is tuned to model fluid behavior from the respective sands accurately. Core flooding results from the Orion Oil Pool in the Schrader Bluff Formation provided the basis for developing relative permeability curves for the various layers in the geological model. The geological model was then coupled with the developed fluid model and introduced into a compositional simulator capable of handling the heterogeneous complexity to simulate CO2 injection. Simulations suggested that the CO2 gas injection is partially miscible in the Orion reservoir at pressures close to the average initial reservoir pressure. Consequently, CO2 mixes with oil in the reservoir, reduces oil viscosity, increases oil mobility, and improves oil recovery. Different simulation scenarios were considered and compared, including the effects of fluid injection mixtures on oil recovery, well trajectory effects, and production bottom hole pressure effects on oil recovery. A considerable volume of injected CO2 is expected to be sequestered in the reservoir, for which economic analysis is conducted for tax credit purposes. The results show that 40% Enriched CO2 injection achieved the highest oil recovery, which highlights the importance of selecting the appropriate injector and producer well trajectory. This work provides insights into the optimum CO2 gas flooding controlling parameters for incremental oil production through sensitivity analysis. The study's novelty is further expanded by quantifying the potential of CO2 sequestration in each layer of the Orion oil field.

Available in PDF, EPUB and Kindle. Book excerpt: Fossil fuels still need to meet the growing demand of global economic development, yet they are often considered as one of the main sources of the CO2 release in the atmosphere. CO2, which is the primary greenhouse gas (GHG), is periodically exchanged among the land surface, ocean, and atmosphere where various creatures absorb and produce it daily. However, the balanced processes of producing and consuming the CO2 by nature are unfortunately faced by the anthropogenic release of CO2. Decreasing the emissions of these greenhouse gases is becoming more urgent. Therefore, carbon sequestration and storage (CSS) of CO2, its utilization in oil recovery, as well as its conversion into fuels and chemicals emerge as active options and potential strategies to mitigate CO2 emissions and climate change, energy crises, and challenges in the storage of energy.
