In Utah, the Beta Member of the Permian Kaibab Formation produces oil at the Ferron field in the western part of the study area, and the Upper Valley field, 30 mi southwest of the study area. Production at Upper Valley field is hydrodynamically controlled; it is unknown if production at Ferron field is hydrodynamically controlled due to the lack of well control.
With the exception of the Ferron and Upper Valley fields, Kaibab oil production has remained an elusive goal. Numerous oil shows have been encountered in dozens of tests of the Beta Member of the Permian Kaibab Formation within the study area. Many of these wells have targeted the crests of small anticlinal structures associated with the San Rafael swell. The history of Upper Valley field, and the lack of Kaibab oil production on the crests of anticlinal structures within the region, creates the potential for hydrodynamically displaced oil to be present within this area.
Results from stratigraphic cross sections and subsurface structural, isopach, and porosity mapping were combined with hydrodynamic mapping methods to define four areas with oil entrapment potential in the Beta Member of the Permian Kaibab Formation.
