Title: In situ thermal processing of a hydrocarbon containing formation to produce oxygen containing formation fluids

Abstract: A hydrocarbon containing formation may be treated using an in situ thermal process. A mixture of hydrocarbons, H.sub.2, 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. The mixture produced from the formation may contain condensable hydrocarbons, with some of the hydrocarbons being oxygen containing hydrocarbons.
