Delaware Basin Map
The counties of the Delaware Basin stretch from Eddy county, New Mexico in the north to Pecos county, Texas in the south. Population sizes range from less than 200,000 in Lea, Eddy, and Chaves Counties in New Mexico to the sparsely populated Loving County of Texas with just over 100 residents. The counties below are located in the Delaware map.

WHAT IS THE DELAWARE BASIN
The basin’s areal extent covers 13,000 square miles, most of which is sparsely populated. The northern end of the basin lies in New Mexico, giving it exposure to federal land which typically carries a lower royalty rate compared the private leases in Texas and some regions of New Mexico.
The Delaware Basin is approximately 2,000 feet deeper than the Midland Basin. This increase in depth has caused, over a long period of time, the sediment to experience over twice as much pressure during burial. This is a leading factor in the stratigraphic discontinuities between the two sub-basins.
DELAWARE BASIN OIL COMPANIES
The prolific oil reserves of the Delaware Basin have attracted the supermajors and leading publicly traded firms. Delaware Basin oil companies also include many smaller independent exploration and production companies. The following table lists top oil companies of the Delaware Basin by barrel of oil equivalent (BOE). The Delaware map shows the operation areas for the Producers
DELAWARE BASIN PLAYS
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.
