In situ thermal processing of a hydrocarbon containing formation in a reducing environment

摘要

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 reducing environment may be maintained within a portion of the formation.
