Mancini, E.A., Scott, R.W., and Llinas, J.C., 2005: Lower Cretaceous Carbonate Petroleum Reservoir Characterization, Northeastern Gulf of Mexico Project, Report 3 - Subsurface Study.
Introduction
Three active Mesozoic petroleum source beds are known from the onshore eastern Gulf Coastal Plain area of Mississippi, Alabama and Florida. These include the Upper Jurassic Smackover source rocks, Lower Cretaceous Sunniland source rocks, and Upper Cretaceous Tuscaloosa source rocks. The total oil and gas production from these three source rocks exceeds 12 Tcf of natural gas and 3 billion barrels of oil.
The purpose of this 2 year research project, as outlined in the revised proposal of January 24, 2002, is to provide additional data to characterize potential Lower Cretaceous carbonate reservoirs in the continental shelf and slope areas of the northeastern Gulf of Mexico by studying outcrop analogs from the western Gulf Coastal Plain (Texas) and by studying well logs and cores from the subsurface of the onshore central Gulf Coastal Plain (Louisiana). These potential reservoirs are an integral part of any petroleum system that was operative in the northeastern Gulf of Mexico.
The results from the characterization of Lower Cretaceous carbonate lithofacies and biofacies of the western Gulf Coastal Plain (Texas) as observed in outcrop was reported in Report 2 of this project (Milestone Chart).
This report, Report 3, presents the results from the characterization of Lower Cretaceous carbonate lithofacies and biofacies as observed in the subsurface of the central Gulf Coastal Plain (Louisiana).
