ABSTRACT:
A coal formation may be treated using an in situ thermal process. A mixture of hydrocarbons, H2, and/or other formation fluids may be produced from the formation. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. Heat may increase a permeability of the formation. The permeability may increase uniformly throughout the treated formation. The permeability of the treated portion may increase to a relatively high permeability as compared to an initial permeability of the untreated coal formation. The porosity of the treated formation may also uniformly increase.
