Delaware Basin – Wolfcamp

Wolfcamp Play Map

Wolfcamp Horizontal Production

The graphic above presents cumulative Delaware Basin oil production for all horizontals completed since 2008 in the Wolfcamp. The Wolfcamp is typically divided further into four intervals:

Wolfcamp XY (“WFMP_XY”) – A thinner interval representing the transition between the Bone Spring and Wolfcamp formations. Early development targeted this formation in the “War-Wink” field, initially developed by Anadarko Petroleum Corporation (now Occidental Petroleum Corporation). Both horizontal and vertical spacing of horizontal wells are critical drivers of performance within this interval.

Wolfcamp A (“WFMP_A”) – Significant development in the Wolfcamp A did not start until 2014. Very quickly after this point, production in this target grew significantly across most areas of the basin. Today, the Wolfcamp A accounts for the most development and production amongst all Wolfcamp intervals.

Wolfcamp B (“WFMP_B”) – Relative to the two shallower targets, the Wolfcamp B has been less developed. However, this interval remains a significant target for many operators throughout Reeves, Loving, and Ward Counties. The Wolfcamp B is a thicker target and many operators co-developed along with the Wolfcamp A landing zone.

Wolfcamp C (“WFMP_C”) – The Wolfcamp C is the least developed target of those shown in the production graphic. Development is mainly limited to the northeastern corner of Culberson County and other nearby areas. In general, the Wolfcamp C is considered an upside target which currently lacks the development potential of the other landing zones.

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.
