The Norphlet Reservoir Study is a comprehensive stratigraphic and petrographic study utilizing thirty-six (36) wells that represent 3,800 feet of Norphlet section from onshore and offshore Alabama, eastern Mississippi, and the Florida panhandle. A total of 349 samples were studied in thin section, eighty-five (85) of which were analyzed by scanning electron microscopy (SEM), with energy dispersive spectroscopy (EDS) and by X-ray diffraction (XRD, and incorporated with routine rock property measurements. Sample depths range from 9,430 feet near the updip limit to 21,960 feet.
The objective of this study is to characterize the environments of deposition, petrology, rock types, and diagenetic features of the Norphlet Formation and to determine the extent of their effect on reservoir quality. Regional trends and local variations in reservoir quality are also delineated. Recommended precautions for drilling completion as well as well-log analyses are discussed.
