Delaware Basin – Landing Bench Overview

Delaware Basin Play Map

Horizontal Production by Landing Bench

The graphic above presents all Delaware Basin horizontals completed since 2008. Horizontals within the Basin are landed within the following benches:

Bone Spring (“BSPG”) / Avalon – The Bone Spring is typically divided further into 1st, 2nd, and 3rd Bone Spring benches. Each Bone Spring bench is comprised of an alternating carbonate-sand sequence. Generally, the Bone Spring has been developed more heavily to date in New Mexico than in Texas, and the 2nd Bone Spring has been the most heavily targeted of the three benches.

Wolfcamp – The Wolfcamp is typically divided further into Wolfcamp XY, A, B, and C benches. Generally, the Wolfcamp has been developed more heavily to date in Texas than in New Mexico, and the Wolfcamp A has been the most heavily targeted of the four benches.

Other – Since 2008, Delaware Basin Horizontals completed outside of the Bone Spring/Avalon, or Wolfcamp have generally targeted the Delaware Mountain Group (e.g., Bell Canyon, Cherry Canyon, or Brushy Canyon) or Barnett/Woodford intervals at Alpine High.

Methodology Overview

VSO reviewed and correlated formation tops across more than 3,000 digital and raster open hole logs throughout the Delaware 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.

Reservoir & Geologic Studies

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

Assessment of Development Potential and Risks

Type Well Analysis

Evaluation of Well Performance and Interference

Midstream/Supply Studies

Audits/Evaluations of Producing Assets

Key Cross-Sections

Reservoir Quality Maps – Porosity, TOC, OOIP

Upside development Reservoir Quantity Maps – Gross and Net Isopachs

Pressure Trends
