The Georgetown carbonates of the Maverick Basin in south Texas are a poorly understood play, despite having produced in excess of two million barrels of oil from the Wipff Field in the past 50 years. Seismic attribute work is integrated with geomechanics and the structural history of the area to develop a fractured carbonate model for the play. We propose that migrating hydrocarbons are trapped in an extensive fault and fracture network near the top of the mechanically competent Georgetown, and sealed by the overlying ductile Del Rio shale. The area of interest for future exploitation lies within Cretaceous-age shear zones where highly faulted and fractured areas are identified using four different seismic attributes. We discuss the model’s impact on well design and highlight three proof-of-concept wells.
