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.
