"The Stratton field is a large mature gas field located between Nueces County and Kleberg County in the northwest Gulf Coast Basin of south Texas. The Oligocene middle Frio Formation is one of the major progradational units within the Stratton field. It is characterized by rapid deposition and high subsidence rates that create complex internal facies architecture. The reservoir facies architecture of the middle Frio Formation is described as channel-fill deposits, crevasses-splay deposits, and floodplain mudstones. Previous two-dimensional seismic studies indicate some level of compartmentalization. Three-dimensional seismic and well log data provided by the Bureau of Economic Geology at the University of Texas at Austin were utilized to identify by-passed, untapped, incompletely drained, and new infield reserves. North-South trending features were observed within the basal middle Frio Formations, and are interpreted as residual effects from the deeper Vicksburg Faults. Correlation of the traced horizons and well log data revealed two structural highs in the C-38 time structure map that also appear as high amplitude corresponding to the presence of gas in the reservoir. Two structural closures described as Prospect A and Prospect B were evaluated. For Prospect A, volumetric calculations gave an in-place gas reserves of 501 mmcf and recoverable gas reserves of 351 mmcf. For Prospect B, they yielded an in-place gas reserves of 487 mmcf and recoverable gas reserves of 341 mmcf. At the current price of $4.75/MMBtu, the total value of recoverable gas from both Prospects A and B is $3.29 million"--Abstract, page iii.
