Abstract
The geochemical oil prospecting method is disclosed in which a crude oil sample is analyzed for the presence of distinctive patterns of aromatic sulfur compounds which are indicative of the petroleum source rock type. Using relative proportions of benzothiophenes, dibenzothiophene, isomeric methyl dibenzothiophenes, dimethyl- and trimethydibenzothiophenes a crude oil can be identified as having a carbonate or siliciclastic source. The information obtained can be used in combination with geological and seismic studies to determine potential oil locations.
