METHOD OF INCREASING METHANE PRODUCTION FROM A GEOLOGICAL FORMATION BY INTRODUCING YEAST ADDITIVES INTO THE FORMATION

摘要

Disclosed is a method of stimulating biogenic production of methane, the method comprising: accessing a consortium of microorganisms in a first geologic formation that includes a carbonaceous material; and providing an amendment to the microorganisms consisting exclusively of a yeast extract amendment, wherein the yeast extract amendment comprises one or more components selected from the group consisting of blood meal, fish meal. meat and bone meal, beef peptone, products of barley, products of beet, products of corn, products of cottonseed, products of potato, products of wheat, products of oat, and products of soybean, and wherein the yeast extract amendment stimulates the consortium to metabolise the carbonaceous material into the methane.
