Computer slice maps and proprietary three-dimensional interactive graphics were used to reconstruct the paleodeposition and to map reservoir variations within the Yates Formation of west Texas. The prolific Yates Formation is a major reservoir in the North Ward Estes field, Ward County, Texas. The Upper Permian (Guadalupian) Yates Formation is an overall regressive shallowing-upward package containing variable sequences of subtidal, intertidal, and supratidal strata. Sediment types include various siliciclastics mixed with sabkha-type carbonates and evaporites. The types of rocks and their structures indicate that these sediments were deposited in a prograding tidal flat-lagoonal setting located behind a shelf margin edge on the western flank of the positive Central Basin platform during the Guadalupian. The cyclic nature of the Yates is largely the result of lagoonal expansion and construction that caused environmental belts on both sides of the lagoon to converge and diverge. These rapid migrations of facies coupled with diagenetic processes created the heterogeneities that characterize this large reservoir.
