Biogenic fuel gas generation in geologic hydrocarbon deposits

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...

Beschreibung
Zusammenfassung:	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.
