Abstract (en)

The invention provides an improved two stage process for use on kerogen bearing and/or "heavy oils" wherein the process comprises a two-stage catalytic hydropyrolysis process for recovering biomarkers from a geological oil-bearing sample, said process comprising the steps of: in a first stage heating a geological oil-bearing sample incorporating a dispersed hydrotreating catalyst up to a temperature of from 450 DEG C to 520 DEG C, in the presence of hydrogen at a pressure of from 5 MPa to 15 MPa so as to release into the vapour phase from said geological oil-bearing sample organic compound material containing biomarkers; and in a second stage contacting the material released in the first stage with a hydrotreating catalyst at a temperature in the range of from 300 DEG C to 350 DEG C in the presence of hydrogen at a pressure of from 5 MPa to 15 MPa so as to release chemically bonded biomarkers.
