01 The Basin

On the western edge of the
Delaware Basin.

Culberson County sits in far West Texas, in the western part of the Delaware sub-basin of the Permian, against the New Mexico state line. The Delaware is the most active oil sub-basin in the United States, and over the past decade operators have pushed the productive fairway steadily westward out of the Reeves and Loving core into Culberson, proving up Wolfcamp and Bone Spring rock that earlier generations of drilling never reached.

The county seat is Van Horn, a longtime crossroads town on Interstate 10 that has become a base for oilfield activity in the southern and central parts of the county. Culberson is geographically large and historically sparse, with much of its early production tied to conventional gas. The modern story is horizontal: as completion technology improved and infrastructure extended west, operators built positions across the eastern half of the county where the Delaware section remains thick and oil-charged, grading toward a gassier, wetter stream as you move west and deeper.

Culberson is one of the parts of the Delaware where the play is still expanding. The eastern half carries strong Wolfcamp and Bone Spring rock, and the western reaches grade gassier as the section deepens.

If you are reading this, you may own a piece of that. Maybe you inherited minerals through a chain that goes back to old West Texas ranching families or original land patents. Maybe you have been receiving royalty checks for years. Maybe an operator just sent you a letter asking to lease unleased acreage. This page walks through the rock, the operators, the sub-geography of the county, valuation, and the regulatory landscape including the role of University Lands and state acreage.

02 The Rock

Stacked pay across the
Delaware column.

Culberson County's productive geology is built around two primary modern unconventional targets, the Wolfcamp and the Bone Spring, with legacy conventional gas production from deeper and shallower zones across parts of the county. The stream grades oilier in the east and gassier toward the west, which shapes both well economics and the post-production cost picture for mineral owners.

Wolfcampthe deep anchor target

The Wolfcamp is the deepest and one of the most productive unconventional targets in Culberson County. It is divided into multiple distinct benches (Wolfcamp A, B, C, and D), and across the eastern half of the county the Wolfcamp A and B carry most of the horizontal development. The interval is thick here, and as the section deepens westward the stream grades gassier and wetter.

For mineral owners, Wolfcamp development typically means multiple wells per spacing unit drilled over the life of development. Modern Wolfcamp completions in Culberson use very large amounts of proppant and longer laterals than first-generation wells, with each well representing a separate revenue stream tied to the same minerals.

Bone Springthree stacked sands

Above the Wolfcamp sit the three Bone Spring sands, each a separate horizontal target. In Culberson County, the 2nd and 3rd Bone Spring sands carry most of the activity in the developed eastern half, and operators pair them with the Wolfcamp below. Bone Spring quality is strong where the section is fully developed, and selective activity continues westward as operators extend programs.

For mineral owners, Bone Spring inventory matters because it stacks on top of Wolfcamp inventory. A spacing unit with productive Bone Spring sands plus Wolfcamp potential supports many years of drilling on the same minerals.

Conventional Gas & Shallowerlegacy and secondary zones

Culberson has a long conventional gas history, with legacy production from deeper Devonian and other zones in the western part of the county, plus shallower intervals across the area. Much of the county's earliest activity targeted these conventional gas reservoirs, and some legacy wells still produce.

The practical implication for mineral owners is that even areas without heavy modern horizontal development may carry legacy conventional production, and spacing units in the developed east may have additional inventory across multiple intervals. The gassier western stream also makes lease cost-deduction language especially worth understanding here.

03 The Operators

Who is drilling on your
Culberson County minerals.

The Permian Basin operator landscape consolidated dramatically through 2023 and 2024, with multi-billion-dollar mergers reshaping who holds which acreage. The operators below are among the most active in Culberson County, but there are many additional meaningful operators across the county.

i.
ConocoPhillips
ConocoPhillips holds one of the larger acreage positions in the western Delaware, much of it built through the 2021 Concho Resources acquisition and the 2024 Marathon Oil combination. The company has been a consistent developer of Wolfcamp and Bone Spring inventory in and around Culberson, with a long drilling queue across its West Texas position.
Major · Delaware core
Top in Culberson
ii.
Chevron
Chevron holds one of the largest overall Permian positions, including legacy acreage across the western Delaware tied to its long history in the basin and its significant non-operated and operated footprint. Chevron has been a steady developer across its position, and royalty owners in Culberson may see the Chevron name on division orders.
Major · Large Permian
Top in Culberson
iii.
Cimarex & Coterra Legacy
Cimarex Energy was an early and active developer of the western Delaware in Culberson before its 2021 merger with Cabot Oil & Gas formed Coterra Energy. Many wells across the county still carry the Cimarex name in older records even where the acreage is now operated by Coterra. Royalty owners may see name changes on division orders and check stubs reflecting this history.
Legacy · Now Coterra
Many Legacy Wells
iv.
Mewbourne Oil Company
Mewbourne is one of the largest private operators in the Delaware Basin, with acreage across the western Delaware corridor including parts of the Culberson area. The company has been a consistent Permian developer for decades. Privately held operators like Mewbourne report less public information than the majors, but Mewbourne's drilling pace and well results have been steady.

04 The Geography

Not all Culberson County
minerals are built the same.

Culberson County covers roughly 3,800 square miles in far West Texas, one of the larger counties in the state. The productive Delaware fairway concentrates in the eastern half, grading west toward gassier streams and conventional legacy production. Van Horn is the county seat. Where in the county your minerals sit shapes everything from operator activity to formation depth, stream quality, and value.

Eastern Culberson / Reeves Border
Eastern townships
The eastern part of the county against Reeves County, one of the most active Delaware Basin counties. This is where modern Wolfcamp and Bone Spring development is most concentrated in Culberson, with operators drilling continuously across the boundary. Mineral interests here often benefit from the spillover of Reeves-focused programs.
Activity: High Development: Active, oil-weighted
Northern Culberson / New Mexico Line
Northern townships
Northern Culberson meets the Eddy County, New Mexico state line, where the Delaware fairway continues into the New Mexico Permian. Wolfcamp and Bone Spring quality is strong here, and cross-state-line acreage dynamics occasionally affect leasing as operators run programs on both sides of the boundary.
Activity: High Development: Active
Central Culberson
Around Van Horn
The central part of the county around Van Horn sits at the transition between the developed eastern fairway and the gassier, deeper west. Activity here is selective, concentrated where the Delaware section remains thick and the economics support drilling. Infrastructure along the I-10 corridor supports operations.
Activity: Moderate Development: Selective
Western Culberson
Western reaches
Western Culberson grades into the deeper, gassier part of the Delaware and toward the basin margin. Historically this is conventional gas country, and modern horizontal activity is more limited and economics-dependent here. Legacy gas production continues across parts of the western county.
Activity: Lower Development: Gas-weighted, legacy
University Lands Acreage
Scattered tracts
The University of Texas / Texas A&M University Lands system holds substantial mineral acreage across West Texas, including tracts in and around Culberson County. Mineral interests adjacent to University Lands may interact with University leasing dynamics that differ from purely private acreage. The University Lands system runs its own leasing process.
Activity: Active University leasing Development: Major mineral owner
Southern Culberson
Southern townships
Southern Culberson runs toward the Delaware Mountains and the basin's structural edge. Activity here is selective and tied to where the Delaware section remains productive. Much of this area is rugged and sparsely developed, with mineral value concentrated where modern drilling reaches.
Activity: Selective Development: Edge of fairway
05 Your Valuation

What your Culberson County
mineral rights are worth.

Valuation in Culberson County reflects its position on the expanding western edge of the Delaware. The oil-weighted eastern fairway supports solid valuations, while the gassier west is more dependent on commodity outlook and processing economics. The four scenarios below cover what we see most often.

01
Producing Minerals with Active Royalty Income
Valued on cash flow plus remaining inventory
If your Culberson County minerals are actively producing, valuation typically starts with the trailing twelve months of royalty income. A buyer applies a multiple based on expected remaining well life, future drilling potential across Wolfcamp and Bone Spring intervals, the oil-versus-gas mix of your stream, and commodity outlook. Eastern Culberson multiples tend to be solid; the gassier west depends more on gas and NGL pricing.
What shapes the number: well vintage and remaining life, how many additional Wolfcamp and Bone Spring locations remain undrilled, your stream's oil-gas mix, your royalty rate, the operator quality, and your lease cost-deduction language.
02
Unleased Minerals in Active Development
Valued on drilling proximity and future potential
Unleased Culberson County minerals, particularly in the eastern fairway near Reeves and along the New Mexico line, are valued on expected development timing. Operators are extending programs west, which supports lease bonus and royalty rate negotiations in the active areas. Unleased minerals in the developed east carry meaningful optionality; western tracts depend more on whether the play reaches them.
What shapes the number: nearby permit activity, the operator's recent drilling pace in your area, formation quality and stream beneath your specific section, comparable lease bonuses paid on surrounding tracts, and whether the section is part of an operator's near-term drilling plan.
03
Small Fractional Interests & Inherited Positions
Often worth more than expected
Many Culberson County mineral owners hold small fractional interests inherited across multiple generations, often spread across heirs in different states. Even small fractional interests in the active eastern fairway can carry meaningful value. We pay these interests the same attention as larger ones and are comfortable doing the title research, including chains that go back to original land patents and old West Texas ranching families.
What shapes the number: net mineral acre count, royalty rate if leased, producing status, accumulated unpaid suspense (sometimes meaningful for inherited interests), and whether other heirs holding the same chain are also active.
04
Leased but Not Yet Producing
Valued on lease terms and proximity to activity
If your Culberson County minerals are leased but not yet producing, value depends substantially on the lease terms and how quickly the operator is moving toward drilling. Permian leases typically have three to five year primary terms with extension by production. A lease held by an active operator extending its western program is worth materially more than one held by a passive leaseholder waiting on conditions.
What shapes the number: your royalty rate, primary term expiration, the specific operator holding the lease, recent drilling activity in adjacent spacing units, and whether your lease has a Pugh clause or similar acreage-protection language.

06 The Regulatory Landscape

Texas rules,
Permian realities.

Culberson County operates under the Texas oil and gas regime, administered primarily by the Texas Railroad Commission. The on-the-ground realities reflect the role of University Lands as a significant mineral owner in parts of West Texas, the long history of Texas common law on mineral and royalty issues, and the practical workings of the modern western Delaware play.

The Texas Railroad Commission and how spacing works

The Texas Railroad Commission (RRC) regulates oil and gas activity in Texas. Culberson County falls within RRC District 8, which covers much of the Permian. The RRC permits wells, conducts hearings on spacing and pooling, and maintains the public well database. Texas uses field rules that vary by reservoir, and modern horizontal development in the Delaware typically uses larger units that match two-mile or longer laterals.

University Lands and institutional minerals

The University of Texas / Texas A&M University Lands system is one of the largest mineral owners in West Texas, holding lands originally granted to the universities to support higher education. University Lands acreage is leased through a separate process and is held to fund the Permanent University Fund. If your minerals are adjacent to or interspersed with University Lands, the University leasing dynamics may affect timing of nearby drilling.

Texas mineral law and cost deductions

Texas common law treats the marketable-product question differently depending on lease language. Many older Texas leases allow post-production cost deductions for gathering, processing, transportation, and compression. This matters more than usual in Culberson, where the gassier western streams carry meaningful processing and gathering costs. Newer leases sometimes include cost-free royalty or "no deductions" language. Reading your specific lease's royalty and cost-allocation language carefully matters in Texas.

Pooling, allocation wells, and PSA wells

Texas does not have compulsory pooling in the same way some other states do, which has led to creative legal structures for horizontal wells that cross multiple tracts. "Allocation wells" and "production sharing agreement wells" are increasingly common. These structures affect how royalty is allocated to mineral owners along the lateral. Understanding which structure your wells use is worth the time.

07 Questions We Hear Often

The real questions
mineral owners ask.

We have been through these conversations hundreds of times. Below are honest answers to the things people actually want to know. For more, see our frequently asked questions.

01
How much are mineral rights worth in Culberson County, Texas?
Culberson County values reflect its position in the western Delaware Basin, where Wolfcamp and Bone Spring development has expanded steadily as operators pushed the play west. Values vary widely depending on where in the county your minerals sit, whether they are leased or producing, the oil-gas mix of your stream, the operator, your royalty rate, and lease cost-deduction language. The only way to know what your specific minerals are worth is to look at the actual facts. We are happy to do that for you, at no cost and with no obligation to sell.
02
Where is Culberson County in the Permian and why does it matter?
Culberson County sits in far West Texas in the western part of the Delaware sub-basin of the Permian, against the New Mexico line. It is north of Reeves County and west of Loving County. The western Delaware here carries a thick Wolfcamp section and productive Bone Spring sands, and the play has expanded westward into Culberson over the past decade as operators extended their programs from the basin core.
03
I inherited mineral rights in Culberson County but I do not have any documents. What do I do?
You are not alone. This is one of the more common situations we see. Start by gathering anything you do have: old letters from operators, tax statements, probate records, royalty stubs, division orders. The Culberson County Clerk's office in Van Horn keeps deed records. The Texas Railroad Commission maintains a public database of wells and operators. We can usually identify what someone owns with just a name and a rough idea of where the minerals are located.
04
Should I sell my Culberson County mineral rights now or hold them?
That depends on your situation. People who hold typically want long-term royalty income, do not need cash for other priorities, and are comfortable with commodity price volatility. People who sell typically want certainty, want to simplify their estate, or want to use the capital for something else. Culberson County's western Delaware position supports both cases. Neither path is wrong. We can help you think through the tradeoffs without pressure to pick a side.
05
What is the difference between an offer to lease and an offer to buy my minerals?
Leasing gives an operator the right to develop your minerals for a period of time, typically three to five years, with extension if production is established. In exchange you receive a bonus payment per net mineral acre and a royalty percentage on any production. You still own the minerals. Buying transfers ownership entirely, in exchange for a lump sum. After a sale, you no longer own the minerals and you receive no future royalties. Both have their place.
06
My royalty statements have cost deductions. Is that normal in Texas?
It is common in Texas, and whether your specific lease permits which deductions depends entirely on the lease language. Many older Texas leases allow post-production cost deductions for gathering, processing, and transportation. This matters in Culberson because parts of the county produce gassier, wetter streams that carry meaningful processing costs. Newer leases sometimes include cost-free royalty language. Reading your lease carefully and checking how the operator is calculating deductions is worth doing. We can help review your statements and lease language together if helpful.
07
How does drilling on University Lands or state acreage affect my situation?
The University of Texas system owns substantial mineral acreage across parts of West Texas, and state-owned tracts also exist in Culberson County. If your minerals are adjacent to University Lands or state acreage, those leasing dynamics may affect timing of nearby drilling. University Lands acreage is leased on different terms than fee minerals. We can help sort out the implications for your specific tract.
08
Can I sell mineral rights I inherited if other family members inherited the same minerals?
Yes, you can sell your undivided fractional interest without needing the other heirs to participate. This is extremely common in Culberson County, where many interests have been subdivided across generations of heirs, often spread across multiple states. A good buyer will work with your specific interest, not require you to round up cousins. We do this all the time.
09
How does the sale process actually work?
Step one, we do the research. You send us what you have, we pull Texas Railroad Commission records, we check operator activity in the area, and we build an analysis. Step two, we walk you through what we see and how we arrived at the number, on a call or by email. Step three, if you want to proceed, we handle the mineral deed preparation, you sign at a notary, and funds are wired at close. We move on your timeline. There is no charge for the research and no obligation to sell.
10
Why should I sell to Timberline Minerals specifically?
We are a family-owned office with roots in Montana and Texas. We work across the primary US basins and we are comfortable with western Delaware specifics including Wolfcamp development, the Bone Spring sands, the gassier western fairway, and the Texas Railroad Commission process. We work with mineral interests of all sizes including small fractional positions. Our process is straightforward: we research the tract, share what we find, and make an offer. The decision to sell is yours.
