The Leonardian succession in the Eastern Shelf of Permian Basin typically displays a wide range of geologic and petrophysical properties that make the efficient recovery of hydrocarbons difficult, once known as the largest uneconomical field in the Permian Basin. Despite decades of exploitation, recovery from the Leonardian rarely exceeds 8-12%. Lack of scientific attention hampered any application of new methods for reservoir analysis. In this study, high-frequency sequence architecture and 3-D seismic attribute analysis combined with wireline-log data have been launched to correct this situation and to characterize the reservoirs. This effort has involved four sequence stratigraphic units and various sedimentary facies types are identified on siliciclastic-carbonate dominated shelf margin. These new studies provide an important basis for future evaluations of Leonardian potential.
