OSTI ID:6745942
The objectives of this research program are to develop microbial enhanced oil recovery (MEOR) systems for application to reservoirs containing medium to heavy oils and to evaluate reservoir wettability and its effects on oil recovery. The MEOR research goals include: (a) the development of bacterial cultures that are effective for oil displacement under a broad range of reservoir conditions; (b) improved understanding of the mechanisms by which microbial systems displace oil under reservoir conditions; (c) determination of the feasibility of combining microbial systems with or following conventional enhanced oil recovery (EOR) processes, such as miscible and immiscible gas flooding, polymer and chemical flooding, and thermal methods; (d) development of an MEOR field process design; and (e) implementation of an industry cost-shared field demonstration project. The goals of the reservoir wettability project are to develop: (a) a better methods for assessment of reservoir core wettability, (b) more certainty in relating laboratory core analysis procedures to field conditions, (c) a better understanding of the effects of reservoir matrix properties and heterogeneity on wettability, and (d) improved ability to predict and influence EOR response through control of wettability in reservoirs. Accomplishments for this quarter are described for: MEOR research and field applications; and evaluation of reservoir wettability and its effects on oil recovery.
