Available in PDF, EPUB and Kindle. Book excerpt: Injecting chemicals in reservoirs is an efficient technique to improve oil recovery. In this study, several types of Ionic Liquids (ILs) were initially screened using the Conductorlike Screening Model for Realistic Solvents (COSMO-RS) model. COSMO-RS, in particular, is capable of providing predictions of the thermodynamics properties of ILs. A comprehensive screening study of 148 probable cations and 46 anions was performed in order to shed some light on the interaction of ILs with hydrocarbons via the calculation of the capacity of the screened ILs to hydrocarbons fractions and water. The most suitable ILs for our purposes were chosen, and employed for improving heavy oil (14o API) recovery from sand pack at room conditions taking the cost, physical and chemical properties of the ILs into consideration. The selected ILs were 1-Dodecyl-3- methylimidazolium chloride [DMIM][Cl], 1-Ethyl-3-methylimidazolium acetate [EMIM][Ac], 1-Ethyl-3-methylimidazolium methyl sulfate [EMIM][MS], 1-Hexyl-3- methylimidazolium tetrafluoroborate [HMIM][Bf4], 1-Butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [BMIM][Tf2N], 1-Methyl-3-octylimidazolium tetrafluoroborate [MOIM][Bf4], 1-Methyl-3-octylimidazolium hexafluorophosphate [MOIM][PF6], 1,3-Dimethylimidazolium tosylate [dMIM][TOS], 1-Benzyl-3- methylimidazolium tosylate [BenzMIM][TOS], N-methylpyridinium tosylate [MPyr][TOS], 1-Ethyl-3-methylimidazolium chloride [EMIM][Cl], 1-Benzyl-3- methylimidazolium chloride [BenzMIM][Cl], and Trihexyltetradecylphosphonium chloride [THTDPh][Cl].

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Saskatchewan, Enhanced Oil Recovery (EOR) techniques were applied in many light and medium oil reservoirs in order to improve oil recovery. One of the most efficient EOR methods is chemical flooding. This research studied the efficiency of introducing various types of Ionic Liquids (ILs), 1-Ethyl-3-Methyl-Imidazolium Acetate ([EMIM][Ac]), 1-Ethyl-3-methylimidazolium chloride ([EMIM][Cl]), 1-Benzyl-3- methylimidazolium chloride ([BenzMIM][Cl]), and Trihexyltetradecylphosphonium chloride ([THTDPh][Cl]), on the recovery factor (RF) of medium oil, (Weyburn oil, 30.25 oAPI),at room conditions. The main focus of this research was to investigate the effects of IL concentration, Slug Size (SS), and IL + brine slug initiation time on the (RF). The runs carried out demonstrated that oil recovery cannot economically increase beyond using the optimum concentration of IL in the mixture of displacing fluid and that the most efficient injection time of the chemical slug was at the beginning of the flooding procedure (as secondary flooding mode). In addition, the effect of ILs concentrations on the Surface Tension (SFT), pH, wettability alteration, and viscosity of the displacing phases were also investigated. Finally, it was shown that the potential of injecting a slug of IL + brine is much better than that of introducing a slug of alkali + brine. Moreover, the combination of IL and alkali (AIL) resulted in better RF than injecting either of them alone. On the other hand, introducing a slug of polymer + brine was more efficient than the others in terms of developing the recovery factor, but the combination of an IL slug and polymer slug resulted in a better RF , 91.68%OOIP, than injecting either of them alone.

Download or read book Application of Different Types of Solvents for Heavy Oil Recovery written by Kwang Hoon Baek and published by . This book was released on 2020 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various challenges in heavy oil recovery come from the low mobility of reservoir oil. For example, the heavy-oil displacement by water results in a large mobility ratio and therefore, inefficient volumetric sweep. Polymer flooding is the traditional method to improve the frontal stability of the oil displacement, but the polymer mobility is often optimized to be greater than the oil mobility because increasing the polymer viscosity adversely affects the oil production rate. The low mobility of reservoir oil also results in a large amount of steam required in steam-assisted gravity drainage (SAGD), one of the commercially successful methods of bitumen recovery. This research investigated the application of unconventional solvents for heavy oil recovery, such as dimethyl ether (DME), organic alkalis, and surface active solvents (SAS), as a potential additive to the injection fluid. These solvents are not conventionally used for enhanced oil recovery (EOR). The first part of the dissertation presents potential methods of improving the efficiency of SAGD by using water-soluble solvents. Phase-behavior data were obtained for mixtures of bitumen and water-soluble solvents. Experimental results indicated that use of organic alkalis at low concentrations (e.g., 0.5 wt% pyrrolidine) in low-salinity brine can yield efficient emulsification of bitumen in water. The affinity of the organic alkali for asphaltic bitumen was important for oil-in-water emulsification at a wide range of temperatures. The second part of the dissertation presents a potential method of improving polymer flooding by SAS that reduces the interfacial tension (IFT) between the oleic and aqueous phases. Results showed that the IFT reduction by three orders of magnitude (i.e., 15.8 to 0.025 dynes/cm) gave a reduced residual oil saturation and a delayed polymer breakthrough in polymer flooding experiments with no preceding water flood. When the straight polymer flooding resulted in an oil recovery factor of 47% at 1.0 pore-volume injected (PVI), the SAS-improved polymer flooding increased it to 63% with a SAS slug of 0.1 wt% for 0.5 PVI or 0.5 wt% for 0.1 PVI

Download or read book Modern Chemical Enhanced Oil Recovery written by James J.Sheng and published by Gulf Professional Publishing. This book was released on 2010-11-25 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crude oil development and production in U.S. oil reservoirs can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. During primary recovery, the natural pressure of the reservoir or gravity drive oil into the wellbore, combined with artificial lift techniques (such as pumps) which bring the oil to the surface. But only about 10 percent of a reservoir's original oil in place is typically produced during primary recovery. Secondary recovery techniques to the field's productive life generally by injecting water or gas to displace oil and drive it to a production wellbore, resulting in the recovery of 20 to 40 percent of the original oil in place. In the past two decades, major oil companies and research organizations have conducted extensive theoretical and laboratory EOR (enhanced oil recovery) researches, to include validating pilot and field trials relevant to much needed domestic commercial application, while western countries had terminated such endeavours almost completely due to low oil prices. In recent years, oil demand has soared and now these operations have become more desirable. This book is about the recent developments in the area as well as the technology for enhancing oil recovery. The book provides important case studies related to over one hundred EOR pilot and field applications in a variety of oil fields. These case studies focus on practical problems, underlying theoretical and modelling methods, operational parameters (e.g., injected chemical concentration, slug sizes, flooding schemes and well spacing), solutions and sensitivity studies, and performance optimization strategies. The book strikes an ideal balance between theory and practice, and would be invaluable to academicians and oil company practitioners alike. Updated chemical EOR fundamentals providing clear picture of fundamental concepts Practical cases with problems and solutions providing practical analogues and experiences Actual data regarding ranges of operation parameters providing initial design parameters Step-by-step calculation examples providing practical engineers with convenient procedures
