This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Procurement, construction, and installation of unconsolidated sand packs and equipment for displacement studies up to 5000 psi is complete and the equipment is in routine use. One accomplishment was sampling equipment for taking samples at pressures up to 8000 psi during displacement and phase behavior studies. 21 displacements have been made using synthetic crudes. Results suggest that miscibility can be generated between pure CO/sub 2/ and this oil at 1100 psig. At a displacement temperature of 109/sup 0/F, miscibility is generated through multiple contacts and the data suggest that the generation mechanism is one of condensation rather than vaporization. In displacements in which the injection gas was a CO/sub 2/-CH/sub 4/ mixture, the minimum miscibility pressure appears to increase approximately linearly with increasing methane content. Increased CH/sub 4/ concentrations over those originally present were observed in all displacements where the pressure was less than that required for first contact miscibility. Thus it was tentatively concluded that the presence of a bank is not in itself an indication that miscibility was not attained, but only an indication that the mechanism was one of generation of miscibility through mass transfer (multiple contacts).

Download or read book Carbon Dioxide Chemistry Capture and Oil Recovery written by Iyad Karamé and published by BoD – Books on Demand. This book was released on 2018-08-16 with total page 268 pages. 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.

Download or read book Enhanced Oil Recovery Field Case Studies written by S. Lee and published by Elsevier Inc. Chapters. This book was released on 2013-04-10 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the enhanced oil recovery (EOR) survey in Oil and Gas Journal (2010), approximately 280,000bbl of oil per day or 6% of US crude oil production was produced by carbon dioxide (CO2) EOR. Just like any other gas injection processes, field CO2 flooding projects suffer from poor sweep efficiency due to early gas breakthrough, unfavorable mobility ratio, reservoir heterogeneity, viscous fingering and channeling, and gravity segregation. Many of these problems are believed to be alleviated or overcome by foaming the injected CO2. Since the 1970s, CO2-foam flooding has been used as a commercially viable method for EOR processes. Foams, defined as a mixture of internal gas phase in a continuous external liquid phase containing surfactant molecules, can improve sweep efficiency significantly by reducing gas mobility, especially in the reservoirs with a high level of geological heterogeneity. This chapter consists of three main parts: the first part (Section 2.1) deals with fundamentals on foams in porous media and recent advances in this field of research, including three foam states (weak-foam, strong-foam, and intermediate states) and two steady-state flow regimes of strong foams; the second part (Section 2.2) overviews field examples of foam-assisted CO2-EOR processes; and the third part (Section 2.3) covers typical field injection and production responses if CO2-foam pilot or field-scale treatments are successful.

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.

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.
