Finkelstein says that based on initial results, the company's process could extend the lifetime of natural-gas wells. Conventional techniques for extracting natural gas from coal kill the gas-producing organisms found naturally in these coal beds, first, by removing the water that they need, and second, by exposing them to oxygen, which is deadly to them. By carefully maintaining conditions favorable to the microorganisms, the company allows them to continue digesting the coal and producing methane. The company could also employ its techniques to collect useful fuel from coal that's inaccessible to conventional mining, Finkelstein says.
