Abstract

See full text

In-situ heating of coal facilitates desorption and diffusion of the methane for production of the methane through a wellbore. Water within fractures of the coal forms an electrical conduit through which current is passed. The heating relies at least in part on resistivity of the water, which thereby preheats the coal for the recovering of the methane.
