METHODS, STRAINS, AND COMPOSITIONS USEFUL FOR MICROBIALLY ENHANCED OIL RECOVERY: ARCOBACTER CLADE 1

摘要

Methods, microorganisms, and compositions are provided wherein oil reservoirs are inoculated with microorganisms belonging to Arcobacter clade 1 and medium including an electron acceptor. The Arcobacter strains grow in the oil reservoir to form plugging biofilms that reduce permeability in areas of subterranean formations thereby increasing sweep efficiency, and thereby enhancing oil recovery.
