Permian Basin Sub-Basins
What is the Delaware Basin?
The Delaware Basin extends from Lea and Eddie counties, NM, in the north down to Pecos County, TX, in the south. 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.
What is the Midland Basin?
The Midland Basin spans roughly 14,000 square miles, extending from Lynn County, TX, in the north down to Crockett County, TX. The Midland-Odessa metropolitan area, the most populous in the Permian Basin region, sits atop the core of the Midland Basin and is home to about 340,000 people (ACS, 2018).
What is the Central Basin Platform?
The Central Basin Platform is in many ways the backbone of the Permian Basin.
While not as aerially extensive as the Midland or Delaware at 6,400 square miles, migrated oil from the basins charged the shallow carbonate reservoirs to create prolific, albeit localized, conventional fields along the Platform’s edges, many of which have transitioned to secondary and tertiary recovery.
Primary target formations include the San Andres, Clear Fork, Tubb, Devonian and Grayburg. Most operators on the Central Basin Platform are small, privately held companies.
What are the Major Permian Basin Formations?
Wolfcamp Shale
The Wolfcamp formations of the Permian Basin represent a time of rapid sediment deposition into the basin when it was at it’s deepest
Spraberry Play of the Midland Basin
The Lower Spraberry
The Lower Spraberry formation is the most targeted of the Spraberry intervals and is characterized by carbonate and shale and layers.
The Middle Spraberry
The Middle Spraberry is an emerging target with similar geologic characteristics to the Lower Spraberry, though is shallower stratigraphically, and is separated from the Lower Spraberry by the Jo Mill. The Upper Spraberry is the least proven.
Bone Spring Play of the Delaware Basin
The Bone Spring Play is a thick package of alternating sands, shales and carbonate intervals in the Delaware Basin, though is primarily targeted in Eddy & Lea counties in New Mexico. The Bone Spring formations overlie the Wolfcamp Shale.
