METHODS, STRAINS, AND COMPOSITIONS USEFUL FOR MICROBIALLY ENHANCED OIL RECOVERY: PSEUDOMONAS STUTZERI

摘要

Methods, microorganisms, and compositions are provided wherein oil reservoirs are inoculated with microorganisms belonging to Pseudomonas stutzeri and medium including an electron acceptor. The Pseudomonas stutzeri 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.
