摘要:
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. The formation to be treated may be selected based on initial elemental oxygen to carbon ratio of the formation.
摘要:
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. 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.

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. The formation to be treated may be chosen so that the mixture produced from the formation will have a desired amount of condensable hydrocarbons and non-condensable hydrocarbons. The formation to be treated may be chosen based on an initial vitrinite reflectance of the formation.
摘要:
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. Heat sources within a relatively thin layer of hydrocarbon material may be positioned in a staggered pattern near to edges of the layer so that superposition of heat from the heat sources allows a large percentage of the layer to reach a desired temperature.

A oil shale 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 sources may be used to heat the formation. The heat sources may be positioned within the formation in a selected pattern.

摘要:
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 pressure within a majority of a selected section of the formation may be controlled and/or maintained to alter a composition of the produced mixture.
摘要:
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.
