ABSTRACT: Formation Temperature and Formation Pressure Influence the Oil and Gas Distribution in Tertiary Gulf Coast Sediments

Walter H. Fertl, W. G. Leach

Oil and gas distribution is generally influenced by both formation temperature and formation pressure. The present paper provides an analytical study of these parameters. In the clastic Tertiary Gulf Coast sediments, the highest concentration of all hydrocarbons is encountered near the onset of abnormally high formation pressure regimes. This conclusion is based on pressure and temperature data in over 20,000 wells and actual production data from approximately 33,000 well completions.

Similar observations are presented for the Tertiary clastic sediments, located offshore Malaysia, and the Pliocene reservoirs under development in the West Turkmen depression in the USSR.
