Fusselman/Devonian Study of the Midland Basin


The Fusselman-Devonian study of the Midland Basin is designed to enhance exploration and development efforts that are directed at the prolific Fusselman and overlying Siluro-Devonian reservoirs. Early development for these reservoirs occurred along the Fusselman truncation edge and on large seismically defined structures. Recent activity has concentrated on smaller scale structural anomalies downdip from the Fusselman pinchout. These “structural” reservoirs show strong stratigraphic control on reservoir development and distribution.

Correlations of 1,317 wells were made by defining 11 regional markers from the Silurian and Devonian. This geodigital framework provides clients with a valuable resource for interpreting the complex factors affecting reservoir quality.

The study covers a six-county area including Dawson, Borden, Martin, Howard, Midland, and Glasscock counties in Texas, within which 1,317 wells were correlated, and represents several man-years of geologic research.
