A coal formation may be treated using an in situ thermal process. 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. After production of the mixture is ended, the portion may be cooled to produce a spent portion of the formation.
1. A method of forming a spent portion of formation within a coal formation, comprising: transferring heat from heaters to a first portion of the formation to pyrolyze hydrocarbons within the first portion and to establish a substantially uniform permeability within the first portion; and cooli
