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 high hydrogen partial pressure within the formation may allow for hydrogenation of formation fluid within the formation. In addition, hydrogen, from produced formation fluid or from another source, may be used to hydrogenate produced fluid in a surface hydrogenation unit.
