Abstract
Techniques for hydrocarbon recovery from a carbonate reservoir include injecting a microbial stimulation fluid including H2 which enters a region of the reservoir that includes CO2 and a microbial culture which converts at least a portion of the H2 and CO2 into a byproduct to promote dissolution of carbonate compounds in the region of the reservoir, thereby increasing porosity of the region to promote hydrocarbon recovery.
