Book excerpt: In this work, an integrated experimental and numerical investigation was implemented to evaluate carbon dioxide (CO2) enhanced oil recovery (EOR) and geological sequestration using core samples from the Yanchang Formation in the Ordos Basin, China, a sandstone formation representative of tight oil reservoirs. The first study phase, laboratory experiments, examined and quantified the fundamental mechanisms of CO2 displacement via interfacial tension tests, viscosity measurements, contact angle measurements, and constant composition expansion tests. For both unfractured and fractured core samples, three injection strategies of CO2 continuous flooding, water alternative gas injection (WAG: CO2), and cyclic CO2 injection were examined. For fractured core samples, CO2 foam/surfactant alternative gas injection (SAG) was also evaluated. WAG and CO2 foam/SAG injections were superior to continuous CO2 injection for oil recovery but inferior in CO2 storage due to pore-occupation by intermittent liquid-slug injections. Cyclic CO2 injection was the most effective dual-purpose injection strategy though its effectiveness was reduced by preferential breakthrough in fractures. Secondly, a multiphase compositional simulation study examined CO2 displacement in an unfractured tight core. This phase included digital core reconstruction, sensitivity analysis of saturation functions, history match of the three laboratory-tested injection strategies, and their optimization. Modeling verified the laboratory observations and led to additional findings: (1) extended soaking enhanced oil recovery but was limited by the low CO2 injection rate; (2) increasing the cycle size for favorable mobility control improved WAG injection performance; (3) total CO2 injection volume for the improved sweeping volume was the most important factor in cyclic CO2 injection.

This book was released on 2022 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon dioxide (CO2) capture, utilization, and storage (CCUS) is becoming a major climate change mitigation strategy. Some key issues that have limited accelerated development are injectivity losses due to near-wellbore salt precipitation during geological sequestration and poor displacement efficiency during utilization for enhanced oil recovery. To understand and mitigate these challenges, a pore-scale approach that combines flow tests with digital rock physics is proposed. This was implemented to visualize, quantify, and assess CO2/oil/brine/rock interactions that culminate in salt precipitation. It was also used to evaluate the pore morphology changes and the oil recovery performance encountered during carbonated water injection (CWI). In the studies on salt precipitation, three evolution stages—advection-dominated, transition, and diffusion-dominated evaporative drying—were observed. A new mechanism that occurs during the transition from advection to diffusion-limited flow termed reverse solute diffusion was also delineated. This mechanism was typified by upward solute diffusion from regions of lower concentration within the aqueous phase to a highly concentrated evaporating front. The time required for precipitation initiation was shorter in an intermediate-wet carbonate than in a weakly oil-wet carbonate. Higher amounts of salt deposits were formed in the more hydrophilic (intermediate-wet) carbonate, leading to an intensification of porosity reduction in this rock. In addition, the presence of oil within the pore space did not hinder the precipitation process but suppressed the reverse flow of solutes toward the evaporation front, thereby creating localized precipitation at the front. Mineral dissolution via CWI-induced reactive transport is one way to increase near-wellbore injectivity. In experiments involving oil/carbonated water/carbonate rock systems, flow channeling resulted in significant mineral dissolution. This led to the formation of high-conductivity wormholes with two distinct patterns. The first was a conical wormhole formed at a low flow rate where diffusion was significant. Whereas, the second was a dominant wormhole developed at a higher injection rate where advection controlled the transport of reactive species to the flow boundaries. Experiments performed to determine the underlying oil recovery mechanisms during CWI in oil-wet carbonate rocks revealed that carbonated low salinity seawater containing definite amounts of potential determining ions (Ca2+, Mg2+, and SO42−) promotes superior oil recovery compared to other brine samples. This enhanced performance was evidenced by the dominance of wettability reversal to near-neutral states, which created a more favorable capillary pressure required for pore-level displacements. Wettability alteration originated from the reduction in electrostatic attraction between oil/brine and brine/rock interfaces through the surface adsorption of SO42− ions in low-pH environments.

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 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to evaluate the efficacy of using CO2-enhanced oil recovery (EOR) in the East Canton oil field (ECOF). Discovered in 1947, the ECOF in northeastern Ohio has produced approximately 95 million barrels (MMbbl) of oil from the Silurian 'Clinton' sandstone. The original oil-in-place (OOIP) for this field was approximately 1.5 billion bbl and this study estimates by modeling known reservoir parameters, that between 76 and 279 MMbbl of additional oil could be produced through secondary recovery in this field, depending on the fluid and formation response to CO2 injection. A CO2 cyclic test ('Huff-n-Puff') was conducted on a well in Stark County to test the injectivity in a 'Clinton'-producing oil well in the ECOF and estimate the dispersion or potential breakthrough of the CO2 to surrounding wells. Eighty-one tons of CO2 (1.39 MMCF) were injected over a 20-hour period, after which the well was shut in for a 32-day 'soak' period before production was resumed. Results demonstrated injection rates of 1.67 MMCF of gas per day, which was much higher than anticipated and no CO2 was detected in gas samples taken from eight immediately offsetting observation wells. All data collected during this test was analyzed, interpreted, and incorporated into the reservoir characterization study and used to develop the geologic model. The geologic model was used as input into a reservoir simulation performed by Fekete Associates, Inc., to estimate the behavior of reservoir fluids when large quantities of CO2 are injected into the 'Clinton' sandstone. Results strongly suggest that the majority of the injected CO2 entered the matrix porosity of the reservoir pay zones, where it diffused into the oil. Evidence includes: (A) the volume of injected CO2 greatly exceeded the estimated capacity of the hydraulic fracture and natural fractures; (B) there was a gradual injection and pressure rate build-up during the test; (C) there was a subsequent, gradual flashout of the CO2 within the reservoir during the ensuing monitored production period; and (D) a large amount of CO2 continually off-gassed from wellhead oil samples collected as late as 3 1/2 months after injection. After the test well was returned to production, it produced 174 bbl of oil during a 60-day period (September 22 to November 21, 2008), which represents an estimated 58 percent increase in incremental oil production over preinjection estimates of production under normal, conditions. The geologic model was used in a reservoir simulation model for a 700-acre model area and to design a pilot to test the model. The model was designed to achieve a 1-year response time and a five-year simulation period. The reservoir simulation modeling indicated that the injection wells could enhance oil production and lead to an additional 20 percent recovery in the pilot area over a five-year period. The base case estimated that by injecting 500 MCF per day of CO2 into each of the four corner wells, 26,000 STBO would be produced by the central producer over the five-year period. This would compare to 3,000 STBO if a new well were drilled without the benefit of CO2 injection. This study has added significant knowledge to the reservoir characterization of the 'Clinton' in the ECOF and succeeded in identifying a range on CO2-EOR potential. However, additional data on fluid properties (PVT and swelling test), fractures (oriented core and microseis), and reservoir characteristics (relative permeability, capillary pressure, and wet ability) are needed to further narrow the uncertainties and refine the reservoir model and simulation. After collection of this data and refinement of the model and simulation, it is recommended that a larger scale cyclic-CO2 injection test be conducted to better determine the efficacy of CO2-EOR in the 'Clinton' reservoir in the ECOF.

Book excerpt: Geological sequestration of CO2, whether by enhanced oil recovery (EOR), coal-bed methane (CBM) recovery, or saline aquifer injection is a promising near-term sequestration methodology. While tremendous experience exists for EOR, and CBM recovery has been demonstrated in existing fields, saline aquifer injection studies have only recently been initiated. Studies evaluating the availability of saline aquifers suitable for CO2 injection show great potential, however, the long-term fate of the CO2 injected into these ancient aqueous systems is still uncertain. For the subject study, a series of laboratory-scale CO2 flood tests were conducted on whole core samples of the Mt. Simon sandstone from the Illinois Basin. By conducting these tests on whole core samples rather than crushed core, an evaluation of the impact of the CO2 flood on the rock mechanics properties as well as the geochemistry of the core and brine solution has been possible. This empirical data could provide a valuable resource for the validation of reservoir models under development for these engineered CO2 systems.

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.

This book was released on 2013 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Capturing carbon dioxide (CO2) from stationary sources and injecting it into deep underground geologic formations has been identified as a viable method for reducing carbon emissions to the atmosphere. Sedimentary rocks, such as sandstones overlain by shales or evaporites, are the preferred formations because their morphology and structure provide pore space, and containment for the long term storage of CO2. Sandstone formations have also served as repositories to migrating hydrocarbons, and are the sites of many oil recovery operations. For many depleted oil reservoirs, secondary waterflooding recovery methods are no longer efficient or economically viable, hence the application of tertiary CO2 enhanced oil recovery (CO2-EOR) followed by CO2 storage is an attractive and cost effective business plan. Citronelle Oil Field, located in southwest Alabama, is the largest and longest producing sandstone oil reservoir in the state, having produced more than 170 million barrels of oil from its estimated 500 million barrels of original oil in place, since its discovery in 1955. The field is in the later stages of secondary recovery by waterflooding and daily oil production has declined considerably. The field is comprised of the Upper and Lower Donovan hydrocarbon bearing sandstones, which are separated by the saline-water-bearing sandstones of the Middle Donovan. The Ferry Lake Anhydrite, which overlies the three sections, serves as their caprock. The present work is focused on an investigation of the feasibility of a CO2-EOR project for the Citronelle Oil Field and the use of the Middle Donovan for long term CO2 storage. A set of static calculations, based on estimation methods which were retrieved from publications in the field, was followed by computer simulations using MASTER 3.0, TOUGH2-ECO2N, and TOUGHREACT. Results using MASTER 3.0, for simulation of CO2-EOR, indicated that nearly 50 million barrels of additional oil could be produced by tertiary recovery. Results using TOUGH2-ECO2N and TOUGHREACT, for the simulations of CO2 storage, indicated that 159 million metric tons (175 short tons) of CO2 could be stored in the Middle Donovan formation. An investigation into possible CO2 leakage from the reservoirs indicated that the Ferry Lake Anhydrite serves as a very reliable long term storage seal. The present work can serve as a template for preliminary assessment of tertiary oil recovery and CO2 storage of similar oil reservoirs and saline-water formations.

Book excerpt: This book is based on the laboratory and field research on Langgak Field, operated by SPR Langgak as one of Province-Owned Oil Company. This book is written to be a guideline and to add knowledge related to enhanced oil recovery (EOR) activity, particularly CO2 Injection. The authors are aware that the information about EOR activity in Indonesia is still limited, so with the presence of this book, we hope it can be made as a reference, not only for students but also for engineers and other researchers who would like to carry out or perform EOR project using CO2 Injection. The authors realize that there are some flaws in the completion of this book. Nonetheless, the authors believe this book will serve as a foundation for other CO2 EOR projects in Indonesia and improve the readers' understanding of CO2 Injection activity. Special thanks are given to the Director of PT. SPR Langgak, Mr Ikin Faizal, who gave us excellent support in the making of this book.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambro-Ordovician strata of the Midwest of the United States is a primary target for potential geological storage of CO2 in deep saline formations. The objective of this project is to develop a comprehensive evaluation of the Cambro-Ordovician strata in the Illinois and Michigan Basins above the basal Mount Simon Sandstone since the Mount Simon is the subject of other investigations including a demonstration-scale injection at the Illinois Basin Decatur Project. The primary reservoir targets investigated in this study are the middle Ordovician St Peter Sandstone and the late Cambrian to early Ordovician Knox Group carbonates. The topic of this report is a regional-scale evaluation of the geologic storage resource potential of the St Peter Sandstone in both the Illinois and Michigan Basins. Multiple deterministic-based approaches were used in conjunction with the probabilistic-based storage efficiency factors published in the DOE methodology to estimate the carbon storage resource of the formation. Extensive data sets of core analyses and wireline logs were compiled to develop the necessary inputs for volumetric calculations. Results demonstrate how the range in uncertainty of storage resource estimates varies as a function of data availability and quality, and the underlying assumptions used in the different approaches. In the simplest approach, storage resource estimates were calculated from mapping the gross thickness of the formation and applying a single estimate of the effective mean porosity of the formation. Results from this approach led to storage resource estimates ranging from 3.3 to 35.1 Gt in the Michigan Basin, and 1.0 to 11.0 Gt in the Illinois Basin at the P10 and P90 probability level, respectively. The second approach involved consideration of the diagenetic history of the formation throughout the two basins and used depth-dependent functions of porosity to derive a more realistic spatially variable model of porosity rather than applying a single estimate of porosity throughout the entire potential reservoir domains. The second approach resulted in storage resource estimates of 3.0 to 31.6 Gt in the Michigan Basin, and 0.6 to 6.1 Gt in the Illinois Basin. The third approach attempted to account for the local-scale variability in reservoir quality as a function of both porosity and permeability by using core and log analyses to calculate explicitly the net effective porosity at multiple well locations, and interpolate those results throughout the two basins. This approach resulted in storage resource estimates of 10.7 to 34.7 Gt in the Michigan Basin, and 11.2 to 36.4 Gt in the Illinois Basin. A final approach used advanced reservoir characterization as the most sophisticated means to estimating storage resource by defining reservoir properties for multiple facies within the St Peter formation. This approach was limited to the Michigan Basin since the Illinois Basin data set did not have the requisite level of data quality and sampling density to support such an analysis. Results from this approach led to storage resource estimates of 15.4 Gt to 50.1 Gt for the Michigan Basin. The observed variability in results from the four different approaches is evaluated in the context of data and methodological constraints, leading to the conclusion that the storage resource estimates from the first two approaches may be conservative, whereas the net porosity based approaches may over-estimate the resource.

Available in PDF, EPUB and Kindle. Book excerpt: CO2 Enhanced Oil Recovery (CO2 -EOR) has been a mature technology for more than 40 years. This EOR process offers opportunities to mitigate CO2 emissions through co-optimization of CO2 sequestration and EOR. In this thesis, we focus on the Tensleep Sandstone to simulate CO2 -EOR and sequestration, and analyzed the effect of different injection scenarios. Research has been conducted to study mechanisms in CO2 -EOR and CO2 -sequestration, respectively. CO2 -EOR mechanisms in the simulation included CO2 dissolution in crude oil to decrease viscosity and swelling crude oil. For CO2 sequestration, CO2 was allowed to get trapped in the pore space by hysteresis effects and dissolved in formation water through solubility. Based on a geostatistical model with detailed information on the reservoir geology, a dynamic model was built using the compositional simulator CMG-GEM. Simulation results for CO2 -EOR and sequestration in Tensleep B sandstone will serve future economic evaluations and reservoir development design. The sequence of injection influences oil recovery; the best timing for CO2 injection to obtain a maximum oil recovery is the beginning of reservoir exploitation. When it comes to CO2 sequestration, the best timing of CO2 injection leading to the maximum storage volume is after continuous water injection. For water-alternating-gas scenarios, six month cycles are recommend, based on the high oil recovery observed and perceived lower operating cost.
