摘要 |
A method is disclosed for treating a hydrocarbon containing formation in situ and producing a hydrocarbon fluid from the formation, wherein hydrocarbons present in the formation are pyrolysed at an elevated pressure with the application of a pressure/temperature control such that the pressure is at least the pressure which can be calculated for a selected temperature, or the temperature is at most the temperature which can be calculated for a selected pressure from the equation (I) wherein P is pressure (bar absolute), T is temperature ( DEG C), and A and B are predetermined parameters which relate to a property which is relevant to the quantity, the composition or the quality of the hydrocarbon fluids produced. Optionally the method is followed by the step of producing synthesis gas in-situ which step comprises reacting the hydrocarbon containing formation that has been treated with the method according to the invention with a synthesis gas generating fluid. Optionally converted hydrocarbons are produced by converting the synthesis gas so produced into hydrocarbons and/or energy is generated by expanding and/or combusting the synthesis gas so produced or using the synthesis gas so produced in a fuel cell. |
