A method for treating a hydrocarbon containing formation.

摘要

A method is disclosed for treating a hydrocarbon containing formation in-situ and producing a hydrocarbon fluid from the formation, which method comprises pyrolysing hydrocarbons present in the formation at a hydrogen partial pressure of at least 1 bar and at most 50 bar, thereby producing hydrocarbons having a high API gravity, a low carbon number and a low olefins and poly-aromatic compound content.
