This book was released on 2018 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Unconventional Liquids Rich Reservoirs (ULR) such as Bakken, Niobrara, and Eagle Ford have become the main target for oil and gas investors as conventional formations started to deplete and diminish in number. These unconventional plays have a huge oil reserve; however, the predicted primary oil recovery is still low as an average of 7.5 %. Unconventional Improved Oil Recovery (UIOR) techniques are still a new concept in the oil industry because there is no commercial project for any IOR technique so far. Injecting carbon dioxide (CO2) might be the most potential strategy to improve oil recovery in such complex plays. In this study, three different approaches were combined to investigate the applicability of CO2-EOR in these unconventional reservoirs. Firstly, experimental data analysis for the feasibility of CO2-EOR was conducted on 95 cases of natural preserved core samples collected from different shale formations. Secondly, a numerical simulation study was conducted to upscale the reported experimental-studies outcomes to the field conditions. Thirdly, CO2-EOR performances in some of the fields' pilots performed in Bakken formation were matched and analyzed by using numerical simulation methods. This study found that the kinetics of oil recovery process in productive areas and CO2-diffusivity level in the field scale of ULR are the keys to perform a successful CO2-EOR project. The results also diagnosed the gap between CO2 performances in lab-conditions versus to what happened in field pilots. Geomechanics coupling has a clear effect on CO2-EOR performance; however, different geomechanics approaches have a different validity in these shale plays. Finally, this research provided deep insights on how CO2-EOR is different in conventional reservoirs as in unconventional formations"--Abstract, page iv.

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.

Download or read book CO2 Storage Coupled with Enhanced Oil Recovery written by Kun Sang Lee and published by Springer Nature. This book was released on 2020-03-09 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive and detailed description of the various mechanisms of the CCS–EOR process. Whereas previous texts have primarily focused on carbon capture and storage (CCS) and enhanced oil recovery (EOR) separately, this book provides a general overview of both technologies when used together. Coupled CCS–EOR technology has become increasingly important, as it overcomes the respective shortcomings of the two technologies. The book presents an integrated numerical model including the hysteresis effect, solubility trapping, miscibility, and formation damage by asphaltene deposition. The experimental and model-based evaluation of fluid properties is also discussed. The book concludes by discussing the latest research into CO2 storage coupled with EOR, most notably performance control by including additives in CO2 injection, and CO2 injection into shale reservoirs. Ideally suited for graduate students and researchers in the fields of carbon capture, utilisation, and storage, the book shares essential insights into maximising the efficiency of CCS and EOR alike.

Available in PDF, EPUB and Kindle. Book excerpt: Data from the US Department of Interior - Bureau of Ocean and Energy Management - 2012 Offshore Gulf of Mexico Atlas were analyzed to: (i) compute reconnaissance-level estimates of CO2 volumes for storage in sub-seabed offshore Gulf of Mexico (GoM) oil sands before and after carbon dioxide (CO2) enhanced oil recovery (EOR), (ii) investigative technical and economic impacts of CO2 injection in gas-rich offshore GoM hydrocarbon fields, and (iii) analyze legal issues and framework associated with offshore geologic sequestration or storage (GS). Part (i) of this study, Reconnaissance-level estimation of CO2 sub-seabed GS potential in offshore GoM, builds on a similar study conducted by The University of Texas at Austin, Bureau of Economic Geology on potential onshore CO2 GS in the GoM region, published in Nunez-Lopez et al. (2008). Part (ii) focuses on the use of two screening methodologies to investigate the impact of native methane (CH4) in recycled CO2. The impact of CH4 on the effectiveness of CO2 as a solvent for EOR is defined by: Calculating minimum miscibility pressure (MMP) of pure CO2 for each oil sand (conventional oil reservoirs), Computing impure CO2 MMP for each oil sand considering only native CH4 as an impurity and neglecting other trace gas components in the oil reservoir. Five to 50 mole percent CH4 impurity factor was computed as a function of the pseudocritical temperature (T[subscript pc]) of the CH4-CO2 mixture. Plotting miscibility against sub-seabed depth, total depth, play type, and API gravity. Part (iii) analyzes existing US outer continental shelf (OCS) regulations under the authority of the US Department of the Interior stated in Title 30 CFR Part 250 and Part 550 to determine their applicability to carbon capture, offshore GS, and CO2 EOR. The study results show a potential storage capacity of approximately 3.5 billion metric tons of CO2 after CO2 EOR for the 3,598 offshore GoM individual oil sands assessed in Part (i). For Part (ii), results indicate that deeper reservoirs are most tolerant to miscible impure CO2 EOR. Of the play types defined by the BOEM, fan and fold belt plays are most tolerant to impure CO2 flooding. Further study on the impact of impure CO2 on MMP resulted in a definition of 18 mole percent as the cutoff for economic and technically viable CO2 flooding in offshore GoM oil fields. When a hypothetical CO2 injection stream exceeded 18 mole percent CH4 contamination, 72% of the case study oil reservoirs became immiscible. In Part (iii), policies that address offshore CO2 GS, CO2 EOR, and both price based and non-price based mechanisms in the OCS would accelerate a shift towards implementing GS and CO2 EOR in offshore GoM.

Available in PDF, EPUB and Kindle. Book excerpt: The stimulation of unconventional hydrocarbon reservoirs is proven to improve their productivity to an extent that has rendered them economically viable. Generally, the stimulation design is a complex process dependent on intertwining factors such as the history of the formation, rock and reservoir fluid type, lithology and structural layout of the formation, cost, time, etc. A holistic grasp of these can be daunting, especially for people without sufficient experience and/or expertise in the exploitation of unconventional hydrocarbon reserves. This book presents the key facets integral to producing unconventional resources, and how the different components, if pieced together, can be used to create an integrated stimulation design. Areas covered are as follows: • stimulation methods, • fracturing fluids, • mixing and behavior of reservoir fluids, • assessment of reservoir performance, • integration of surface drilling data, • estimation of geomechanical properties and hydrocarbon saturation, and • health and safety. Exploitation of Unconventional Oil and Gas Resources: Hydraulic Fracturing and Other Recovery and Assessment Techniques is an excellent introduction to the subject area of unconventional oil and gas reservoirs, but it also complements existing information in the same discipline. It is an essential text for higher education students and professionals in academia, research, and the industry.
