ABSTRACT

A geochemical and isotopic characterization of a wide selection of the produced oils in the petroleum subprovinces from the Mexican Gulf Coast Basin has revealed five major genetic groups. Their distribution and chemical features appear to reflect multiple sources, facies variations, maturation, and postfilling alteration processes. Each group is correlated with a specific generative source, namely (1) Oxfordian marine marl-dominated, (2) Oxfordian marine carbonate-dominated, (3) Tithonian marine marl-dominated, (4) Cretaceous marine carbonate-evaporitic, and (5) Tertiary marine deltaic siliciclastics.
