摘要:
Disclosed herein is introduction of different nutrient solution formulations to a subterranean target site to prevent biofilm formation and biomass aggregation at the sand face of an injection well bore during MEOR or bioremediation processes. A first nutrient solution formulation supports growth of introduced microorganisms and a second nutrient solution formulation is used to promote biofilm formation to allow plugging of pores and channels in the subterranean target site, for MEOR or bioremediation.
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.
