Abstract (en)

[origin: WO2006118570A1] A process for introducing microorganisms to carbonaceous material in an anaerobic environment is described. The process includes the step of extracting formation water from a geologic formation, and removing at least a portion of an extractable material from the formation water to make amended formation water. The process may further include introducing the amended formation water to the carbonaceous material. Also, a process for increasing biogenic hydrocarbon production in a geologic formation containing a carbonaceous material is described. The process includes extracting formation water from the formation, removing at least a portion of one or more hydrocarbons from the formation water to make amended formation water, and reintroducing the amended formation water to the geologic formation.
