ABSTRACT:
A method for increasing pressure in geological oil-bearing structures by gas production due to microbial activity comprising adding to a geological oil-bearing structure, a methane producing aneorobic micro-organism, a culture medium and formic acid. The formic acid is converted to carbon dioxide and methane gases resulting in increased pressure in the structures.
