Abstract
A method of microbial enhanced oil recovery from a wellbore in an oil-bearing formation that includes injecting water into the oil-bearing formation via a tubing string in the wellbore and introducing oxygen into the oil-bearing formation for consumption by microbes in the oil-bearing formation. The oxygen introduction includes delivering the oxygen into the oil-bearing formation without having the introduced oxygen contact the walls of the tubing string and without having the introduced oxygen contact the injected water within the tubing string while the injected water is in the tubing string.
