摘要： Methane production from a carbonaceous material is stimulated by contacting the material with a methanogenic consortium under anaerobic conditions. Active methanogenic consortia can be isolated and concentrated from anaerobic formation water of a methane-producing carbonaceous formation. Data presented herein demonstrate methane production from carbonaceous material that was essentially nonproductive in the absence of contact with a methanogenic consortium.

摘要： Methods of stimulating biogenic production of a metabolic product with enhanced hydrogen content are described. The methods may include accessing a consortium of microorganisms in a geologic formation that includes a carbonaceous material. They may also include providing hydrogen and one or more phosphorous compounds to the microorganisms. The combination of the hydrogen and phosphorous compounds stimulates the consortium to metabolize the carbonaceous material into the metabolic product with enhanced hydrogen content. Also, methods of stimulating biogenic production of a metabolic product with enhanced hydrogen content by providing a carboxylate compound, such as acetate, to a consortium of microorganisms is described. The carboxylate compound stimulates the consortium to metabolize carbonaceous material in the formation into the metabolic product with enhanced hydrogen content.

The methods may include accessing a consortium of microorganisms in a geologic formation that includes a carbonaceous material. They may also include providing a phosphorous compound to the microorganisms. The phosphorous compound stimulates the consortium to metabolize the carbonaceous material into a metabolic product with enhanced hydrogen content. Also, methods of stimulating biogenic production of a metabolic product with enhanced hydrogen content by providing a yeast extract amendment to a consortium of microorganisms is described. The yeast extract amendment stimulates the consortium to metabolize carbonaceous material in the formation into the metabolic product with enhanced hydrogen content.

摘要： Methods to enhance biogenic gas production in an anaerobic geologic formation containing carbonaceous material are described. The methods may include the steps of accessing the anaerobic formation, increasing a rate of production of the biogenic gases in the anaerobic formation, and flowing formation water within the anaerobic formation after the increase in the production of biogenic gases. Also described are methods to redistribute formation water in an anaerobic geologic formation containing carbonaceous material. The methods may include the steps of locating a reservoir of the formation water within the anaerobic formation, forming at least one channel between the reservoir and at least a portion of the carbonaceous material, and transporting the formation water from the reservoir to the carbonaceous material through the channel. Further described are methods of accumulating biogenic gas in an anaerobic geologic formation to enhance biogenic gas production.
