Abstract:
1. A method for enhancement of biogenic methane production comprising the steps of: providing a hydrocarbon-bearing formation having at least two microbial populations; introducing at least one indiscriminate microbial population stimulation amendment to said hydrocarbon-bearing formation having said at least two microbial populations; microbially consuming said at least one indiscriminate microbial population stimulation amendment by said at least two microbial populations; blanket boosting said at least two microbial populations of said hydrocarbon-bearing formation from consumption of said at least one indiscriminate microbial population stimulation amendment; microbially depleting said at least one indiscriminate microbial population stimulation amendment; starving at least one of said at least two boosted microbial populations; selectively reducing said starved at least one of said at least two boosted microbial populations; selectively sustaining said at least one boosted microbial population; generating methane from said at least one boosted microbial population; and collecting said methane.
