  • Publication number: 20100248321
    Abstract: Methods of conditioning a carbonaceous material in a subterranean geologic formation for metabolism into a compound with enhanced hydrogen content by a microorganism consortium are described. The methods may include the steps of accessing the subterranean geologic formation through an access point, and contacting the carbonaceous material with a surfactant. The microorganism consortium can utilize the surfactant as a first nutrient source. The surfactant also increases accessibility of the carbonaceous material as a second nutrient source for the microorganism consortium. The microorganism consortium metabolizes the carbonaceous material into the compound with the enhanced hydrogen content.
