Available in PDF, EPUB and Kindle. Book excerpt: Within the last 10 years the world has come to a point where the easily explorable oil deposits have now been found, and it is anticipated that such deposits will be depleted by the beginning of the Twenty-first Century. However, the increasing demand of man kind for energy has caused technologists to look into ways of find ing new sources or to reevaluat:e unconventional sources which, in the past, have not been economical. In this respect, heavy crude and tar sand oils are becoming important in fulfilling the world's energy requirements. What are heavy crude and tar sand oils? There is still some confusion as to their definitions, inasmuch as they vary among organizations and countries. In an effort to set agreed meanings, UNITAR, in a meeting in February 1982 in Venezuela, proposed the following definitions (see also Table 1): 1. Heavy crude oil and tar sand oil are petroleum or petroleum like liquids or semi-solids naturally occurring in porous media. The porous media are sands, sandstone, and carbonate rocks. 2. These oils will be characterized by viscosity and density. Viscosity will be used to define heavy crude oil and tar sand oil, and density (oAPI) will be used when viscosity measurements are not available. 3. Heavy crude oil has a gas-free viscosity of 100-10000 mPa.s (cp) 3 o at reservoir temperatures, or a density of 943 kg/m (20 API) 3 o o to 1000 kg/m (10 API) at 15.6 C and at atmospheric oressure.

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 Cyclic CO2 Injection for Light Oil Recovery written by and published by . This book was released on 1992 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultimate objectives of the research were to provide a base of knowledge on the cyclic CO2 stimulation (or CO2 huff-n-puff) process for the enhanced recovery of Louisiana crude oil, and to demonstrate the utility of the process to the small independent producer. The project was divided into four subtasks: laboratory coreflood experiments, computer simulation, field testing, and technology transfer. Laboratory corefloods were performed to investigate important process parameters. Computer simulation was used to confirm and expand laboratory coreflood results. A field-test data base was constructed and analyzed to facilitate target reservoir screening and to identify successful operational practices. The laboratory coreflood results and data base evaluations were used in the design and implementation of a field test that was conducted in conjunction with the private sector. The results of laboratory and field studies were disseminated to the industry through presentations at technical conferences and publications in technical journals.

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.

Download or read book Role of C3H8 and CH4 in Enhancing the Foamy Oil Phenomena and Performance of CO2 Based Cyclic Solvent Injection in Heavy Oil Systems written by Arash Ahadi and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: As light oil resources are continuously depleted, heavy oil exploitation is nowadays being put on agenda to meet the ever-increasing energy demand. Cyclic Solvent Injection (CSI) technique holds great promise as a viable approach to produce heavy oil from thin reservoirs where thermal and gravity-dominated recovery methods fail to sufficiency (and economically) recover oil. CSI, with CO2 being used as the solvent, has become a subject of several investigations and considerable speculation in light oil systems. Nevertheless, not too many studies ventured into realm of application of CO2 in heavy oil systems. In addition, importance of C3H8 and CH4 in the injected CO2 stream has been addressed in the literature; however, the details of the optimum mixing ratio of these two hydrocarbon solvents are the main knowledge gap that needs to be addressed. In this study, series of cyclic injection tests of pure CO2, CH4-CO2, C3H8-CO2, C3H8-CH4, and C3H8-CH4-CO2 were conducted at various operating pressures and mixture compositions to different (in terms of viscosity) heavy oil samples. Sand pack models with absolute permeability of kabs = 6-10 D and porosity of ø = 27-32% were used as representatives of a typical heavy oil reservoir. It was attempted to measure the CO2/solvent apparent solubility, solvent-produced oil asphaltene content, duration of produced-oil foamy shape stability, and oil recovery in each cycle to probe into the trend of responsible mechanisms during each cycle of CSI. Results showed that there is an optimum pressure in cyclic CO2 injection process in heavy oil systems; the pressure beyond which the ultimate oil recovery factor (RF) did not notably improve (near 4.82 MPa in this study). Higher concentration of C3H8 in the CO2 stream improved the oil recovery during cyclic injection. However, ultimate RF was not noticeably increased when C3H8 concentration in the mixture exceeded a certain value (near 50 mole% in this study). Although C3H8 showed effective role on the performance of CSI, it was found that the recovery factor reduces with increased CH4 concentration in the CO2 stream. The highest recovery factor of 73.8% was obtained by injecting mixture of 50% C3H8 - 50% CO2 into 1850 mPa.s viscous oil sample under the operating pressure of Pinj = 1.72 MPa. The results of CSI tests on the heavy oil with viscosity of 6430 mPa.s were lower by almost 20% since the solvent solubility was noticeably lower. Performing C3H8-CH4 tests to 6430 mPa.s viscous oil revealed that there is an optimum fraction of C3H8 in CH4 stream (near 50 mole% in this study). Moreover, partially replacement of C3H8 with CO2 (50% C3H8 - 50% CH4 with 30% C3H8 - 40% CH4 - 30% CO2) was effective (and profitable) as the achieved ultimate RF were more or less the same. No oil production was observed after conducting the first cycle injection of optimum quantified solvents on oil with the viscosity of 22 000 mPa.s. Small values of Solvent Utilization Factor (SUF), relatively high values of Solvent Oil Ratio (SOR), and low quality of the produced oil in the last cycles suggest that higher cycle numbers of CSI in heavy oil reservoirs is depending on the economic limits and might be conducted cautiously.
