of secondary, non-associated thermogenic gas is generated from source beds in the southern part of the basin (Mancini et al., 2008). This modeling supports the conclusion of Zimmerman and Sassen (1993) that vertical as well as lateral migration is important in the North Louisiana Salt Basin. Refined Resource Reservoir Assessment The refined assessment of the undiscovered and underdeveloped reservoirs based on basin analysis and petroleum system characterization and modeling indicates that the potential undiscovered reservoirs in the North Louisiana Salt Basin are subsalt Triassic Eagle Mills sandstone and deeply buried Upper Jurassic to Lower Cretaceous sandstone, shale, and limestone. Potential underdeveloped reservoirs include Lower Cretaceous sandstone and limestone and Upper Cretaceous sandstone. The potential Upper Cretaceous sandstone reservoirs are transgressive backstepping facies associated with a transgressive-regressive sequence (Fig. 328). These facies onlap onto the Monroe Uplift, resulting in a combination structural and stratigraphic trap (Figs. 11-13 and 331). Technology Transfer Several presentations on the results of this work have been made at the annual meetings of the American Association of Petroleum Geologists and Gulf Coast Association of Geological Societies by Mancini, Li, Goddard, and Barnaby. Technology transfer workshops have been conducted in Shreveport, Louisiana; Jackson, Mississippi; and Tuscaloosa, Alabama and a fourth workshop is planned for Shreveport in September. Research results from this project have been published in the Bulletin of the American Association of Petroleum Geologists (1 paper by Mancini et al., 2008) and in the Transactions of the Gulf Coast Association of Geological Societies (5 papers-1 by 430
