Abstract: A method of increasing biogenic production of a combustible gas from a subterranean geologic formation may include extracting formation water from the geologic formation, where the extracted formation water includes at least a first species and a second species of microorganism. The method may also include analyzing the extracted formation water to identify the first species of microorganism that promotes the biogenic production of the combustible gas. An amendment may be introduced to the formation water to promote the growth of the first species of microorganism, and the biological characteristics of the formation water may be altered to decrease a population of the second species in the geologic formation.

Abstract: Methods to enhance biogenic gas production in an anaerobic geologic formation containing carbonaceous material 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. Methods to redistribute formation water in an anaerobic geologic formation containing carbonaceous material 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. The methods may also include the accumulation of biogenic gas in an anaerobic geologic formation to enhance biogenic gas production.
