A METHOD FOR TREATING A HYDROCARBON CONTAINING FORMATION

摘要

A method is disclosed for treating a hydrocarbon containing formation in sit u and producing a hydrocarbon fluid from the formation, which method comprises pyrolysing hydrocarbons present in the formation at a pressure of at least 1 .5 bar during the production of the hydrocarbon fluid from the formation. Optionally the method is followed by the step of producing synthesis gas whi ch step comprises reacting the hydrocarbon containing formation which is partly depleted by the method according to the invention with a synthesis gas generating fluid. Optionally the synthesis gas so produced is converted into hydrocarbons and/or energy is generated by expanding and/or combusting the synthesis gas so produced or using it in a fuel cell.
