Hydrocarbon Prospectivity in the West Waha and Worsham-Bayer Fields, Delaware Basin

The west Waha and Worsham-Bayer field, located within the Delaware Basin of western Permian Basin, represents a significant hydrocarbon province with substantial production potential. This study aims to reevaluate the hydrocarbon resources and optimize recovery strategies for these fields by integrating seismic interpretation, petrophysical analysis, and volumetric assessment. Using data from 3D seismic reflection volumes, well logs, and production records, the research applied advanced techniques including seismic-to-well ties, structural and sequence stratigraphic interpretations, and fault-seal analysis. Key findings highlight the identification of four major reservoirs: UML, TF, FF, and ELB. The ELB reservoir, characterized by very high porosity, high permeability, and low water saturation, emerged as the most promising target for hydrocarbon production. The TF and FF reservoirs also demonstrated high potential, while the UML reservoir showed moderate characteristics but high-water saturation. Volumetric assessments supported these findings, confirming the ELB reservoir’s exceptional hydrocarbon potential. The study recommends drilling deeper into the Ellenburger Formation with Wells 42 and 98 to exploit deeper targets, acquiring additional 3D seismic data towards the southeastern basin, and employing enhanced seismic resolution for better facies distribution understanding. Furthermore, the development of a 3D reservoir model incorporating fracture networks and a detailed fault-seal analysis are advised to optimize hydrocarbon recovery. This research provides a comprehensive evaluation of the West Waha and Worsham-Bayer fields, offering actionable insights for maximizing hydrocarbon production through targeted exploration and advanced reservoir management strategies.
