Mancini, E.A., Resource assessment of the in-place and potentially recoverable deep natural gas resource of the onshore interior salt basins, north central and northeastern Gulf of Mexico, U.S. Department of Energy Report,Annual Report, Year 1, 117 p.
Abstract
The principal research effort for Year 1 of the project has been data compilation and petroleum system identification. The research focus for the first nine (9) months of Year 1 was on data compilation and for the remainder of the year the emphasis was on petroleum system identification. Understanding the burial and thermal maturation histories of the strata in the onshore interior salt basins of the North Central and Northeastern Gulf of Mexico areas is important in petroleum system identification. The burial and thermal maturation histories of the strata in these basins and sub-basins are consistent with the rift-related geohistory of these features. Petroleum source rock analysis and thermal maturity modeling indicate that an effective regional petroleum source rock in the onshore interior salt basins, the North Louisiana Salt Basin, Mississippi Interior Salt Basin, Manila Sub-basin and Conecuh Sub-basin, was the Upper Jurassic Smackover lime mudstone. The Upper Cretaceous Tuscaloosa shale was an effective local petroleum source rock in the North Louisiana Salt Basin and the Mississippi Interior Salt Basin. Lower Cretaceous strata were possible source rocks in the North Louisiana Salt Basin and Mississippi Interior Salt Basin given the proper organic facies.
