Abstract

A hydrocarbon containing 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. A pressure within a majority of the portion may be controlled and/or maintained to alter a composition of the produced mixture.
