Abstract

Published data from an organic geochemical study of Recent oolites from the Bahamas and the Persian Gulf suggest that petroleum-bearing oolites may be the source, as well as the reservoir, of the hydrocarbons they contain. This paper advances a scheme for the generation and accumulation of hydrocarbons in oolite reservoirs. It is proposed that, with the exception of leached oolites with oomoldic porosity, petroleum-bearing oolites could be viewed as integrated source-reservoir rocks.
