| Summary: | activity includes infill drilling and varying enhanced and only down-dip from the inter- and supratidal facies. Up- Basin region and are extensive hydrocarbon reservoirs in the cycles on the Northwest Shelf based on sequence geometry, dip shallow and peritidal facies within the transgressive eastern margin of the Central Basin Platform has been exclusively from the deep to shallow subtidal facies in the formations-nations in the Waddell Field using cores, well frequency sequences correspond to Guadalupian 12 and 13 high- frequency sequences described on the Northwest Shelf. The from the Grayburg Formation is also dominated by subtidal in the Waddell Field (East Waddell Ranch) produce almost interpretation was correlated to equivalent. strata on the lithofacies in two high-frequency sequences. These two high- logs, and outcrop analogs. The sequence stratigraphic model divides the formation into two highfrequency cycles Northwest Shelf and compared to known reservoir horizons in peloidal facies and migrates towards the eastern margin of platform and siliciclastic progradation occurred.

Reservoirs producing hydrocarbons since 1935 and current engineering production is dominant in deep to shallow subtidal provide up-dip and overlying seals. recovery strategies. This study establishes a sequence region. The Waddell Field (East Waddell Ranch) on the San Andres and Grayburg formations are separated by a Type I sequence boundary during which subaerial exposure of the stratigraphic framework for the upper San Andres and Grayburg systems tracts and in the overlying high-stand systems tracts the field, higher in the stratigraphy. The Grayburg sequence The upper San Andres and Grayburg formations (Guadalupian) the Waddell Field. On the western margin of the field, transgressive systems tracts of each high-frequency sequence were deposited on carbonate platforms around the Permian which correspond to Guadalupian 14 and 15 high-frequency |
