Abstract

See full text

A hydrocarbon containing formation may be treated using an in situ thermal process. Hydrocarbons, H.sub.2, and/or other formation fluids may be produced from the formation. Heat may be applied to the formation from heat sources to raise a temperature of a portion of the formation to a desired temperature. Some of the heat sources may include heater elements. The heater elements may be lengths of bare metal disposed within wellbores within the formation.
