  • In situ production of synthesis gas from a hydrocarbon containing formation through a heat source wellbore
    Publication number: 20030062154
    Abstract: A hydrocarbon containing formation may be treated using an in situ thermal process. 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 synthesis gas production temperature. A synthesis gas producing fluid may be introduced into the formation to generate synthesis gas. Production wells may be operated at selected temperatures to obtain a desired synthesis gas composition.
