In situ thermal processing of a coal formation by controlling a pressure of the formation |
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.
