(2013-05-03)A model for the evaluation of CO2-EOR projects has been developed. This model includes both reservoir simulation to handle reservoir properties, fluid flow and injection and production schedules, and a numerical economic ...
-
(2012-10-15)With the production from mature oil fields declining, the increasing demand of oil urges towards more effective recovery of the available resources. Currently, the CO2 Floods are the second most applied EOR processes in ...
-
(Texas A&M University, 2005-08-29)Fractured reservoirs have always been considered poor candidates for enhanced oil recovery. This can be attributed to the complexities involved in understanding and predicting performance in these reservoirs. In a fractured ...
-
(2019-06-10)Source rocks, such as organic-rich shale, consist of multi-scale pore structures which include pores with sizes down to nano-scale contributing to the storage of hydrocarbons. During my Ph.D. studies, using molecular ...
-
(2019-07-22)Oil production from the fractured tight reservoirs has been increasing since the early 2000s and now accounts for a large portion of onshore US oil production. Complex fracture network composed of hydraulic fractures and ...
-
(2019-07-09)The addition of surfactants to completion fluids in ULRs is widely believed to boost productivity and prolong well life. Previous laboratory studies have revealed that this approach is capillary-driven via spontaneous ...
-
(2012-02-14)Studying chemical enhanced oil recovery (EOR) in a high-temperature/high-salinity (HT/HS) reservoir will help expand the application of chemical EOR to more challenging environments. Until recently, chemical EOR was not ...

Enhanced Oil Recovery of Viscous Oil by Injection of Water-in-Oil Emulsion Made with Used Engine Oil (2012-08-20)Solids-stabilized water-in-oil emulsions have been suggested as a drive fluid to recover viscous oil through a piston-like displacement pattern. While crude heavy oil was initially suggested as the base oil, an alternative ...
-
(2017-12-06)This experimental research investigates the opportunity to enhance the oil recovery by enhancing the foam stability by the use of surfactants mixtures in comparison with individual surfactants. The mixtures were prepared ...
-
(2021-04-29)In recent years, the rapid decline in the production trend of liquid-rich shale reservoirs calls attention to enhance oil recovery (EOR) methods. One of the most promising EOR methods in unconventional reservoirs is a ...
-
(2019-03-04)Due to complex depositional textures and diagenetic processes, carbonate reservoirs are challenging in terms of recovery. This thesis will present the use of foam flooding as a tertiary recovery technique, and as a means ...
-
(2014-07-24)CO_(2) flooding often results in poor sweep efficiency due to the high mobility ratio caused by its low viscosity. To mitigate this problem, alternate injection of water and CO_(2) slugs (WAG) is widely applied. Recently, ...
-
(2011-02-22)Using a hydrogen donor and a catalyst for upgrading and increasing oil recovery during in situ combustion is a known and proven technique. Based on research conducted on this process, it is clear that widespread practice ...
-
(2011-08-08)This study presents the results of nano-particle and surfactant-stabilized solvent-based emulsion core flooding studies under laboratory conditions that investigate the recovery mechanisms of chemical flooding in a heavy ...
-
(2017-12-06)Oil production from organic rich shale has grown significantly in the last decade due to the combination of hydraulic fracturing and horizontal drilling. Yet, this primary recovery exploitation scheme exhibits fast production ...
-
(2020-01-13)Surfactant injection as additives to steam injection is a concept that has great potential to enhance oil recovery efficiency of heavy oil and bitumen. Steam injection enhances oil recovery by introducing heat to the ...
-
(2011-02-22)Steam Assisted Gravity Drainage (SAGD) is used widely as a thermal recovery technique in Canada to produce a very viscous bitumen formation. The main research objectives of this simulation and experimental study are to ...
-
(2022-04-13)This study investigates how the structure of surfactant molecules interacts with the crude oil/rock/brine system characteristic of unconventional liquid reservoirs. In most cases, the interaction results in the improvement ...
-
(2021-12-07)Previous experimental studies and limited field results have shown that the application of surfactants can be effective in improving recovery from unconventional liquid-rich reservoirs. Most of these studies and field ...
