An Overview of the Geology of the Deep Water Plays in the Gulf of Mexico.


This talk reviews the origin of the Gulf of Mexico including the influence of evaporates (Callovian) on the development of the prolific petroleum system.  It then updates recent activity in the three major plays in the Gulf of Mexico deep water beginning with the revitalized deepwater Jurassic Norphlet (Oxfordian) Appomattox Clastic play which has been extended from the Mobile Bay HT gas play out into the deep waters of the gulf where it becomes an oil play.    Next, the excellent quality Pliocene-Miocene Deepwater Turbidite Play, the main deep water producing channelized turbidite reservoir in the GoM is reviewed.  The talk then concludes with the Lower Tertiary Wilcox and Frio Plays and compares the discoveries in the north with new knowledge being learned as drilling progresses offshore Mexico in the southern part of the basin. The talk concludes by looking at the geology of the deep water plays of Mexico including potential carbonate reservoirs.
