  • In situ thermal processing of hydrocarbons within a relatively permeable formation
    Patent number: 6722431
    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 a first portion of the formation to mobilize hydrocarbons within the formation. Heat may be applied to a second portion of the formation to raise a temperature of the second portion to a pyrolysis temperature. Vaporized hydrocarbons and pyrolysis fluids may be produced from the formation.

  • In situ thermal processing of a coal formation with a selected oxygen content and/or selected O/C ratio
    Patent number: 6722430
    Abstract: A coal 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 formation may be selected that will produce a relatively large amount of condensable hydrocarbons and/or a relatively large amount of non-condensable hydrocarbons. Hydrocarbons within the formation may have a relatively low initial elemental oxygen weight percentage. The formation to be treated may be selected based on initial elemental oxygen to carbon ratio of the formation.

  • IN SITU THERMAL PROCESSING OF A COAL FORMATION AND TUNING PRODUCTION
    Publication number: 20040069486
    Abstract: A coal 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. The mixture may be produced from the formation through production wells. A spacing between production wells, and operating conditions of production wells and heat injection wells, may allow the produced mixture to have a desired ratio of condensable hydrocarbons to non-condensable hydrocarbons.
