ABSTRACT:
A method of microbial enhanced oil recovery includes introducing, into an underground carbonate-containing rock formation that defines an anaerobic environment, denitrifying microorganisms, water, and a source of nitrate ion. The microorganisms reduce the nitrate and produce sulfuric acid which dissolves the rock formation, releasing oil. The microorganisms can be denitrifying Thiobacilli, such as T. denitrificans.
