Relations among hydrocarbon reservoirs, epigenetic sulfidization, and rock magnetization; Examples from the South Texas coastal plain

June 1, 1991

This paper focuses on the association between concentrations of iron disulfide (FeS 2 ) minerals in the shallow subsurface and underlying hydrocarbon accumulations. Such FeS 2 concentrations are the result of migration of either H 2 S or organic constituents from the underlying hydrocarbons. The H 2 S from reservoirs is produced inorganically from sulfate in the reservoir rocks at high temperature (>90 degrees C) and migrates to shallower beds to react inorganically with iron to form FeS 2 . Organic constituents from reservoirs, in contrast, provide nourishment for sulfate reducing bacteria in shallow relatively cool (
