Sell Mineral Rights
in Andrews County,
Texas.
Andrews County sits at the transition between the northern Midland Basin and the Northwest Shelf. That dual character matters: stacked Wolfcamp and Spraberry inventory across most of the county, plus meaningful San Andres conventional production along the shelf. If you own minerals here, the geology probably looks different than your neighbor's. We are happy to help you understand what you have.
Where the Midland Basin
meets the Northwest Shelf.
Andrews County sits in the far western edge of Texas, just south of the New Mexico state line and immediately east of the Central Basin Platform. Geologically, the southern and central parts of the county sit within the northern Midland Basin, while the western and northern edges transition onto the Northwest Shelf. That transition is the defining geological fact of Andrews County.
The practical implication is that mineral owners in Andrews can have very different rocks under their feet depending on where in the county the minerals sit. Sections in the southern and eastern county tend to have deep, stacked Wolfcamp and Spraberry inventory typical of the Midland Basin core. Sections in the western and northern county sit closer to the shelf, where San Andres carbonate production has been developed conventionally for decades and where the Wolfcamp section is shallower and thinner.
If you are reading this, you may own a piece of any of that. Maybe you inherited minerals through a chain that goes back to original Texas patents or old family ranches. Maybe you have been receiving royalty checks for decades from San Andres waterfloods. Maybe an operator just sent you a letter asking to lease unleased acreage for a new Wolfcamp horizontal. This page walks through the rock, the operators, the geography, valuation, and the regulatory landscape.

Stacked unconventional and
shelf carbonate targets.
Andrews County's productive section spans the deep Wolfcamp and Spraberry intervals across most of the county and the shallower San Andres carbonate along the Northwest Shelf. The combination produces a different opportunity set than a pure Midland Basin core county or a pure shelf county. Modern operators develop multiple zones from the same surface pad in the unconventional core, while shelf production continues from a mix of vertical wells, waterfloods, and selective horizontals.
The Wolfcamp formation is the deepest and most productive unconventional target across the southern and central parts of Andrews County. It is divided into multiple distinct benches (Wolfcamp A, B, C, and D), with Wolfcamp A and B as the primary current targets in the Midland Basin. The section is typically thinner and shallower in Andrews than in core Midland Basin counties further south.
For mineral owners, Wolfcamp development typically means multiple wells per spacing unit drilled over the life of development, with each well representing a separate revenue stream tied to the same minerals. Modern Wolfcamp completions use very large amounts of proppant and have steeper initial decline curves than older vintage wells.
Above the Wolfcamp sits the Spraberry, divided into the Lower Spraberry, Middle Spraberry, and Jo Mill intervals. The Spraberry has been productive in this area for decades, originally through vertical wells, and is now a primary horizontal target across much of the Midland Basin including parts of Andrews. The Lower Spraberry and Jo Mill are the most consistently developed horizontal targets.
For mineral owners, Spraberry inventory adds meaningful additional locations on top of the Wolfcamp section. Some spacing units in the southern county now have horizontals in multiple Spraberry intervals plus multiple Wolfcamp benches, leading to substantial accumulated well counts per surface unit.
Along the Northwest Shelf in the western and northern parts of Andrews County, the San Andres formation is a shallow carbonate that has been developed for decades. Production comes from a mix of vertical wells, waterflood projects, and more recently selective horizontal completions. Decline curves are typically much flatter than unconventional wells, which gives San Andres royalty interests a different cash flow profile.
The practical implication for mineral owners along the shelf is that legacy production may continue for many years even with little new drilling activity, and that valuation depends heavily on remaining reserves under existing waterfloods rather than future horizontal locations.
Who is drilling on your
Andrews County minerals.
The Permian operator landscape consolidated dramatically through 2023 and 2024, with multiple multi-billion-dollar mergers reshaping the operator list. The four operators below are leaders in current Andrews County activity, but the county has many additional meaningful operators on conventional shelf production and selective unconventional development.
We know how these operators develop in Andrews County. Happy to give you context on yours.
Not all Andrews County
minerals are built the same.
Andrews County covers about 1,500 square miles in far western Texas. The county sits at a geological transition, and where in the county your minerals sit shapes everything from formation depth to operator activity to whether the relevant production is unconventional horizontal or conventional shelf. The town of Andrews, the county seat, is the regional service hub.
What your Andrews County
mineral rights are worth.
Valuation in Andrews County reflects the county's split character. Unconventional Midland Basin minerals are valued on stacked Wolfcamp and Spraberry inventory and ongoing horizontal development. Northwest Shelf minerals are valued on long-life conventional production, often through established waterflood units. The four scenarios below cover what we see most often.

Texas rules,
Permian realities.
Andrews County operates under the Texas oil and gas regime, administered primarily by the Texas Railroad Commission. The on-the-ground realities reflect Texas's strong fee mineral tradition, the Railroad Commission's permitting and spacing rules, and the practical effects of operator consolidation across the Permian.
The Railroad Commission and how spacing works
The Texas Railroad Commission (RRC) regulates oil and gas activity in Andrews County. The RRC permits wells, conducts hearings on spacing and pooling exceptions, and maintains the public well database. Texas does not have forced pooling in the same form as some other states, which means operators must lease or otherwise secure rights from individual mineral owners to drill across a unit. This generally favors mineral owners in negotiation.
Spacing units and field rules
Most Andrews County activity occurs under field-specific spacing rules established for the relevant Wolfcamp, Spraberry, or San Andres fields. Modern horizontal development typically uses larger units that match two-mile or longer laterals. Older legacy patterns vary, particularly for shallower San Andres production where vertical spacing rules may still apply.
Texas fee mineral tradition and lease language
Texas has a strong fee mineral tradition, with most minerals owned privately rather than by state or federal entities. Lease language is the dominant document governing royalty calculation, deductions, drilling obligations, and continuation. Older Texas leases often have less protective language for mineral owners than newer leases. Reading your specific lease's post-production cost language matters in Texas because the state allows broad latitude for deductions unless the lease prohibits them.
State and University Lands
While most Andrews County minerals are privately owned, certain tracts are owned by the State of Texas or by the Permanent University Fund, which holds mineral rights granted to fund the University of Texas and Texas A&M systems. State and University Lands are leased through public processes and on different terms than private fee minerals. If your minerals are adjacent to state or PUF acreage, the leasing dynamics nearby may differ.

Permian status, April 2026
The Permian produced approximately 6.7 million barrels per day of crude oil in March 2026, the most recent month with confirmed data, accounting for roughly forty-eight percent of total US crude production. Year-over-year growth has slowed from prior peaks but remains positive. For Lea and Eddy mineral owners, the practical takeaway is that operator activity continues to be concentrated in stacked Wolfcamp and Bone Spring development across the Delaware sub-basin, with consolidation among public producers reshaping who operates which spacing units.
