Abstract

See full text

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. Pressure within the formation may be controlled as a function of temperature or temperature within the formation may be controlled as a function of pressure to yield a desired mixture.
