Advanced and Emerging Technologies of Enhanced Oil Recovery (EOR)
Several oil fields are currently under development using different enhanced oil recovery (EOR) methods worldwide, including chemical, thermal, and miscible processes plus other hybrid methods. All of these techniques suffer from several problems of accurate reservoir characterisation, difficult screening actual severe heterogeneous reservoir, pilot design, and field implementations. The goal of this two-day course is to present current problems, advanced solutions, and emerging technologies of different EOR processes.
The course presents conventional and low salinity water floods plus others chemical, gas injection, thermal, advanced EOR processes such as steam assisted gravity drainage (SAGD) method, carbon dioxide-steam process, seismic, electromagnetic and advanced microbial enhanced recovery (MEOR). The course also presents surface facility requirements and problems, technical backgrounds, current status, and future of chemical EOR techniques with field case studies worldwide to screen technical strengths and limitations of these methods. Finally, this two-day course provides recent changes and newly-developed hybrid EOR methods and their applied techniques.
