The Diablo platform lies in the southeastern part of the Basin and Range province of North America. Production from several zones within the Paleozoic section has been established both in basins and shelf edges of the surrounding area. A thick sequence of volcanic rocks covers the platform in Jeff Davis County, Texas. These rocks effectively prevent seismic investigation of the presumed sedimentary section below. Gravity, magnetic, and sparse well data were used in constructing an initial geologic model. A magnetotelluric survey consisting of 18 sites showed shallow resistive anomalies in agreement with magnetic anomalies. The magnetotelluric field data were modeled using the initial geologic model. From well control data, resistivity values for the volcanic rocks, sediments, and basement were set. After successive geophysical modeling, a final geologic model was constructed, which is reconciled with the magnetotelluric, magnetic, and well control data. A possible reef is present on the northeast side of the platform.
