This PhD project progressed petroleum applications of compound specific sulfur isotope analysis. Standard compounds and high S petroleum samples were studied. New discoveries included an enrichment effect on the ?34S values of organic sulfur compounds during petroleum biodegradation; and preservation of the ?34S of organic sulfur compounds in the asphaltene fraction of oils impacted by thermochemical sulfate reduction. Field studies helped identify the source inputs of mixed oils and S-availability during deposition.
