  • In Situ thermal processing of a coal formation to control product composition
    Patent number: 6588503
    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. Heat and pressure applied to the formation may be controlled so that a majority of the hydrocarbons produced from the formation have carbon numbers less than 25. Conditions may be controlled to produce low quantities of olefins in condensable hydrocarbons produced from the formation and low quantities of olefins in non-condensable hydrocarbons produced from the formation.

  • In situ thermal processing of a coal formation in reducing environment
    Publication number: 20020191969
    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 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. The mixture produced from the formation may have a relatively high hydrogen partial pressure, and a large portion of the pressure within the formation may be attributable to hydrogen partial pressure.
