Permian Basin

Reservoir & Geologic Studies

The Permian Basin has emerged as the horizontal development epicenter of North American unconventional reservoirs. The Basin is comprised of two sub-basins: the Midland Basin in the east, and Delaware Basin in the west. The Delaware and Midland Basins are separated by the uplifted Central Basin Platform.

Horizontal wells in the Midland Basin generally produce from shallower intervals than Delaware Basin wells. Both Basins offer numerous “stacked pay” reservoir targets. Midland Basin horizontal development has predominately focused on the Wolfcamp A, B, and Lower Spraberry intervals. Meanwhile, the 2nd Bone Spring, 3rd Bone Spring, Wolfcamp A, and Wolfcamp B intervals have been most heavily targeted within the Delaware Basin.

VSO has completed extensive analysis of well performance and productivity throughout the Delaware Basin. Additional reservoir and geologic capabilities include:
