Abstract

Methods of natural gas production and carbon sequestration are provided. The method includes delivering a feedstock downhole to a coal reservoir, generating biogas within the coal reservoir, and harvesting the biogas. Another method for tracing the migration of biogas in a coal reservoir includes delivering a feedstock downhole to a coal reservoir, generating biogas that is isotopically differentiable from a background gas within the coal reservoir through microbial action, harvesting the biogas, analyzing the biogas from the coal reservoir at the injection well and at one or more offset wells within the same coal reservoir, detecting the biogas at the offset wells using isotopic differentiation, and mapping the migration of the biogas from the injection well to the offset wells using the biogas as an isotopic tracer.
