<p>A method of analysing kerogen which consists of pyrolysing the kerogen, and analysing the pyrolysis vapour produced for its C12 alkane content and optionally its C13 alkane content. The analysis can be used to identify oil and/or gas producing kerogens by measuring the weight ratio of C12 alkane to C13 alkane in the vapour, or by comparing the C12 alkane content of the vapour with that of pyrolysis vapours from non-oil and/or non-gas producing kerogens. The pyrolysis vapour is produced by flash pyrolysis, and is analysed by gas chromatography-quadrapole mass spectrometry. The method may be used to explore for oil and/or gas reserves, by pyrolysing mineral samples taken from various subterranean locations, and analysing any pyrolysis vapours produced therefrom.</p> |
