Midland Basin – Landing Bench Overview

The graphic above presents all Midland Basin horizontals completed since 2008. Horizontal wells within the Basin are landed within the following reservoirs:

• Wolfcamp – The Wolfcamp is typically divided further into Wolfcamp A, B, C, and D benches. Additionally, due to its significant thickness in certain parts of the Basin, the Wolfcamp B is commonly sub-divided into the ‘Wolfcamp B Upper’ and ‘Wolfcamp B Lower.’ The Wolfcamp A and B intervals comprise the ‘Upper Wolfcamp,’ and have been the most heavily targeted intervals by horizontal wellbores in the Basin.
• Spraberry – The Spraberry is typically divided further into the Upper Spraberry, Middle Spraberry, Jo Mill, and Lower Spraberry intervals. The Spraberry intervals emerged as key horizontal targets after initial horizontal development of the Wolfcamp. Within this interval, the Lower Spraberry has been the most commonly drilled horizontal target.
• Other – Since 2008, Midland Basin Horizontals completed outside of the Wolfcamp or Spraberry have been relatively limited. However, there have been “other” horizontal tests both above the Spraberry (e.g., San Andres) and below the Wolfcamp (e.g., Devonian).

The Midland Basin’s discovery well (1923) was the Santa Rita #1, located in Reagan County. Relative to the Delaware Basin, today’s unconventional reservoir targets in the Midland Basin are generally shallower, but the Midland also offers numerous “stacked pay” intervals.

VSO reviewed and correlated formation tops across more than 600 digital and raster open hole logs throughout the Midland Basin. We subsequently created and QC’d structure maps for all key intervals within the Basin. After analyzing the placement of each horizontal wellbore relative to our structural interpretations, landing benches were assigned for all wells.

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