Enhanced oil recovery using microorganisms |
摘要 |
A post-primary oil recovery process is provided in which carbon dioxide-tolerating microorganisms are injected into an oil-bearing subterranean formation and feed on nutrients which are extracted from the oil by carbon dioxide injected and maintained under a pressure of at least about 500 psig. The products of microorganism growth enhance petroleum recovery from the formation.
