Abstract: A well section, designated "Wildcat-I", has been evaluated by a suite of geochemical techniques including pyrolysis and gas chromatography. The operating principles of pyrolysis and gas chromatography are briefly discussed, and the basic interpretations that may be obtained from these data are presented. Pyrolysis alone was sufficient to screen out the poor source rocks but insufficient to unequivocally delineate the oil generation interval. However without pyrolysis neither the quantity of oil generation nor its unrealised potential could have been estimated.
