This book was released on 2021 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: CO2 enhanced oil recovery (CO2-EOR) is a form of carbon storage that has the potential to minimize CO2 emissions while also increasing energy output from newly recovered oil. Louisiana is the 5th largest emitter of energy-related CO2 in the United States, with about 200 million metric tonnes of CO2 emitted annually. Louisiana has over 20,000 oil and gas reservoirs and 287 CO2 point sources. This study used a screening methodology at the reservoir level to identify appropriate CO2-EOR candidate reservoirs in Louisiana and their CO2-EOR reserve estimates. Also, an economic analysis of CO2-EOR was carried out in this thesis, which included sensitivity and scenario analysis. In Louisiana, this study identified 217 reservoirs across 86 oil fields as potential CO2-EOR candidates. According to the Louisiana assessment, the 217 candidate reservoirs have a total of 1.4 billion STB of OOIP and a 205 million STB incremental oil potential worth $12.3 billion. The CO2 storage capacity of these reservoirs is projected to be 100 million metric tons. There are several other suitable candidate reservoirs in Louisiana that were not taken into account in this analysis. When combined with the reservoirs described in this thesis, the incremental oil recovered potential and CO2 reservoir storage capacity will reach 1.5 billion STB and 2.6 billion metric tons, respectively. In Haynesville, Bayou Segnette, and Paradis, case studies were conducted for suitable CO2-EOR candidate reservoirs. The sensitivity studies revealed that the net income and economic viability of a CO2-EOR project are highly dependent on oil price, CO2 cost, and tax policy. CO2-EOR would benefit greatly from the high oil price, low CO2 cost, and low tax policy. Given the current economic situation, the economic analysis indicates that operating successful CO2-EOR projects would be difficult. However, the study also shows that CO2-EOR projects can be made economically feasible by combining 1. tax reductions/exemptions in areas such as royalties, income tax, and severance tax. 2. negotiating lower CO2 prices 3. Increase in tax credit for capturing facilities to lower CO2 prices for storage parties

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 2011 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study by the U.S. Department of Energy identified 21 major oil fields containing more than 95% of the North Slope of Alaska's oil. This study investigates the storage of CO2 in these fields while improving oil recovery. These fields meet the criteria for application of miscible and immiscible CO2-enhanced oil recovery methods and contain about 40 billion barrels of oil after primary and secondary recovery. Volumetric calculations from this study illustrate that these fields have a static storage estimate of 3 billion metric tons of CO2. A ranking produced from this study, mainly controlled by field size and fracture gradient, identifies Prudhoe, Kuparuk and West Sak as possessing the largest storage capacities. This storage capacity includes a 20% safety factor on pressures applied during storage to ensure that the formations are not over pressurized to create or extend fractures and result in gas leakage during the storage process. Simulation studies were carried out using CO2 Prophet to determine the amount of oil technically recoverable and CO2 gas storage possible during this process. Fields were categorized as miscible, partially miscible and immiscible based on the miscibility of CO2 with their oil compositions. Seven sample pools were selected across these categories for simulation study. Comparative studies on pure CO2 and water-alternating-gas (WAG) injection were conducted. WAG ratio and minimum miscibility pressure (MMP) were among the main inputs in these simulations. Ranking these fields showed most recovery and storage potential in miscible pools like Alpine and Tarn, partially miscible pools like Prudhoe and Aurora and immiscible pools like West Sak and Orion. The study concludes that 5 billion metric tons of CO2 can be stored while recovering 14.2 billion barrels of the remaining oil in the fields.

Available in PDF, EPUB and Kindle. Book excerpt: Carbon dioxide enhanced oil recovery (CO2-EOR) and sequestration in depleted oil reservoirs is a plausible option for utilizing anthropogenic CO2 to increase oil production while storing CO2 underground. Evaluation of the storage resources and cost of potential CO2-EOR projects is an essential step before the commencement of large-scale deployment of such activities. In this paper, a hybrid techno-economic evaluation method, including a performance model and cost model for onshore CO2-EOR projects, has been developed based on previous studies. Total 296 onshore oil fields, accounting for about 70% of total mature onshore oil fields in China, were evaluated by the techno-economic method. The key findings of this study are summarized as follows: (1) deterministic analysis shows there are approximately 1.1 billion tons (7.7 billion barrels) of incremental crude oil and 2.2 billion tons CO2 storage resource for onshore CO2-EOR at net positive revenue within the Chinese oil fields reviewed under the given operating strategy and economic assumptions. (2) Sensitivity study highlights that the cumulative oil production and cumulative CO2 storage resource are very sensitive to crude oil price, CO2 cost, project lifetime, discount rate and tax policy. High oil price, short project lifetime, low discount rate, low CO2 cost, and low tax policy can greatly increase the net income of the oil enterprise, incremental oil recovery and CO2 storage resource. (3) From this techno-economic evaluation, the major barriers to large-scale deployment of CO2-EOR include complex geological conditions, low API of crude oil, high tax policy, and lack of incentives for the CO2-EOR project.

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.

Download or read book The Role of Methane in Limiting CO2 EOR written by Prisca Chinwendu Ogbuabuo and published by . This book was released on 2015 with total page 61 pages. 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: This report serves as the final technical report and users manual for the 'Rigorous Screening Technology for Identifying Suitable CO2 Storage Sites II SBIR project. Advanced Resources International has developed a screening tool by which users can technically screen, assess the storage capacity and quantify the costs of CO2 storage in four types of CO2 storage reservoirs. These include CO2-enhanced oil recovery reservoirs, depleted oil and gas fields (non-enhanced oil recovery candidates), deep coal seems that are amenable to CO2-enhanced methane recovery, and saline reservoirs. The screening function assessed whether the reservoir could likely serve as a safe, long-term CO2 storage reservoir. The storage capacity assessment uses rigorous reservoir simulation models to determine the timing, ultimate storage capacity, and potential for enhanced hydrocarbon recovery. Finally, the economic assessment function determines both the field-level and pipeline (transportation) costs for CO2 sequestration in a given reservoir. The screening tool has been peer reviewed at an Electrical Power Research Institute (EPRI) technical meeting in March 2009. A number of useful observations and recommendations emerged from the Workshop on the costs of CO2 transport and storage that could be readily incorporated into a commercial version of the Screening Tool in a Phase III SBIR.

Download or read book Assessing the Effect of Timing of Availability for Carbon Dioxide Storage in the Largest Oil and Gas Pools in the Alberta Basin written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon dioxide capture from large stationary sources and storage in geological media is a technologically-feasible mitigation measure for the reduction of anthropogenic emissions of CO2 to the atmosphere in response to climate change. Carbon dioxide (CO2) can be sequestered underground in oil and gas reservoirs, in deep saline aquifers, in uneconomic coal beds and in salt caverns. The Alberta Basin provides a very large capacity for CO2 storage in oil and gas reservoirs, along with significant capacity in deep saline formations and possible unmineable coal beds. Regional assessments of potential geological CO2 storage capacity have largely focused so far on estimating the total capacity that might be available within each type of reservoir. While deep saline formations are effectively able to accept CO2 immediately, the storage potential of other classes of candidate storage reservoirs, primarily oil and gas fields, is not fully available at present time. Capacity estimates to date have largely overlooked rates of depletion in these types of storage reservoirs and typically report the total estimated storage capacity that will be available upon depletion. However, CO2 storage will not (and cannot economically) begin until the recoverable oil and gas have been produced via traditional means. This report describes a reevaluation of the CO2 storage capacity and an assessment of the timing of availability of the oil and gas pools in the Alberta Basin with very large storage capacity (>5 MtCO2 each) that are being looked at as likely targets for early implementation of CO2 storage in the region. Over 36,000 non-commingled (i.e., single) oil and gas pools were examined with effective CO2 storage capacities being individually estimated. For each pool, the life expectancy was estimated based on a combination of production decline analysis constrained by the remaining recoverable reserves and an assessment of economic viability, yielding an estimated depletion date, or year that it will be available for CO2 storage. The modeling framework and assumptions used to assess the impact of the timing of CO2 storage resource availability on the region's deployment of CCS technologies is also described. The purpose of this report is to describe the data and methodology for examining the carbon dioxide (CO2) storage capacity resource of a major hydrocarbon province incorporating estimated depletion dates for its oil and gas fields with the largest CO2 storage capacity. This allows the development of a projected timeline for CO2 storage availability across the basin and enables a more realistic examination of potential oil and gas field CO2 storage utilization by the region's large CO2 point sources. The Alberta Basin of western Canada was selected for this initial examination as a representative mature basin, and the development of capacity and depletion date estimates for the 227 largest oil and gas pools (with a total storage capacity of 4.7 GtCO2) is described, along with the impact on source-reservoir pairing and resulting CO2 transport and storage economics. The analysis indicates that timing of storage resource availability has a significant impact on the mix of storage reservoirs selected for utilization at a given time, and further confirms the value that all available reservoir types offer, providing important insights regarding CO2 storage implementation to this and other major oil and gas basins throughout North America and the rest of the world. For CCS technologies to deploy successfully and offer a meaningful contribution to climate change mitigation, CO2 storage reservoirs must be available not only where needed (preferably co-located with or near large concentrations of CO2 sources or emissions centers) but also when needed. The timing of CO2 storage resource availability is therefore an important factor to consider when assessing the real opportunities for CCS deployment in a given region.
