01 The Basin

The heart of SCOOP,
on a century of history.

Stephens County sits in south central Oklahoma along the southern margin of the Anadarko Basin, in the area known as the Ardmore and Marietta basin transition. It is the heart of the SCOOP play, the South Central Oklahoma Oil Province, which targets the Woodford and Springer formations horizontally across Stephens, Garvin, Grady, and Carter counties.

Long before SCOOP, Stephens County was an oil county. The Healdton field, partially in southwestern Stephens, came online in 1913 and was one of the great early Oklahoma discoveries. Duncan, the county seat, became headquarters of Halliburton in 1919 and remains an important services town. Cement, in the northeastern corner, was another early field. Thousands of vertical wells across the county still produce from conventional zones, and many Stephens County families have received royalty checks for three or four generations.

Stephens County is unusual because it has two stories. The legacy conventional production from the early 1900s is still meaningful, and the modern SCOOP horizontal play has layered onto the same acreage. Many tracts carry both.

What that means for mineral owners is that valuation here is layered. A small royalty check from a 1960s vertical well may sit on top of undrilled Woodford and Springer inventory underneath. Or you may be in a part of the county where the SCOOP fairway thins, and the value is mostly in legacy production plus optionality. This page walks through the rock, the operators, the geography of the county, valuation, and the Oklahoma regulatory landscape.

02 The Rock

Stacked pay across the
SCOOP column.

Stephens County's productive geology runs deep. The Woodford Shale is the primary horizontal target, with the Springer formation above it as a secondary horizontal play. Above the Springer sit numerous conventional zones (Sycamore, Hunton, Bromide, and shallower) that produced the county's legacy vertical wells. The combination supports multiple types of development across the same acreage.

Woodford ShaleSCOOP primary target

The Woodford Shale is the foundational horizontal target of the SCOOP play. Deposited as an organic-rich marine shale in the Late Devonian, the Woodford is both source rock and reservoir, with thickness and quality that vary across Stephens County. In the SCOOP fairway, the Woodford supports multi-well horizontal development with laterals typically running one to two miles.

For mineral owners, Woodford development typically means a small number of horizontal wells per drilling unit drilled over time, often by a single operator who has consolidated the unit. Modern Woodford completions use substantial proppant volumes and produce primarily oil with significant associated gas in the core, transitioning to wetter gas in deeper portions of the basin.

SpringerSycamore and shallower sands

The Springer formation sits above the Woodford and is a secondary SCOOP target. Springer development is more selective than Woodford, but in the right parts of Stephens County, Springer horizontals have produced strong wells. The Springer interval includes multiple sand bodies that operators target individually depending on geology.

For mineral owners, Springer inventory adds optionality on top of the Woodford. A unit with active Woodford development may have additional Springer wells drilled in future development cycles, generating new royalty streams from the same minerals.

Sycamore, Hunton & Legacy Zonesconventional production

Above the SCOOP horizontal targets sit numerous conventional zones that produced Stephens County's legacy oil and gas. The Sycamore limestone has been a horizontal target in some areas but more commonly a vertical zone. The Hunton, Bromide, and shallower formations have produced for decades through vertical wells, many of which are still active.

For mineral owners, the legacy zones often represent current cash flow even if it is modest. A small but consistent royalty check from a 1960s vertical well is real value, and it sits independently from any future SCOOP development. We see many Stephens County interests where the right way to think about the asset is two layers: the legacy producing zones and the deeper horizontal optionality.

03 The Operators

Who is drilling on your
Stephens County minerals.

The SCOOP operator landscape consolidated significantly through the 2020s. Continental Resources, the original SCOOP pioneer, went private in 2022 and remains the largest operator in the play. Marathon Oil, which had a meaningful SCOOP position, was acquired by ConocoPhillips in 2024. The operators below are leaders in current Stephens County activity.

i.
Continental Resources
Continental Resources is the original SCOOP pioneer, having identified and developed the play starting around 2012. The company holds the largest SCOOP position by net acres and remains the most active SCOOP driller. Continental went private in late 2022 when Harold Hamm took the company private but operates with the same Oklahoma-headquartered team. Continental's Stephens County activity is concentrated in the Woodford fairway with selective Springer development.

ConocoPhillips (Marathon legacy)
Marathon Oil had built a significant SCOOP position in Stephens and Grady counties over the 2010s. ConocoPhillips acquired Marathon in late 2024, and the SCOOP acreage is now part of the ConocoPhillips Lower 48 portfolio. The legacy Marathon wells and undeveloped inventory in Stephens County continue to be developed under ConocoPhillips operatorship.

Long Tail of Legacy Vertical Operators
Stephens County has a long tail of small operators who maintain legacy vertical wells across the county. These operators may not drill new wells, but they keep older production alive and continue to pay royalties. Mineral owners may see operator names on royalty stubs that they have never heard of. This is normal and reflects the county's century-long production history.

04 The Geography

Not all Stephens County
minerals are built the same.

Stephens County covers about 890 square miles in south central Oklahoma. Duncan, the county seat and Halliburton's historical headquarters, sits in the center. The SCOOP horizontal fairway runs across the central and eastern parts of the county. The Healdton field area in the southwest has a different character. Where in the county your minerals sit shapes everything.

Duncan / Central Core
T1N-T2S R7W-R8W
The central part of the county around Duncan sits in the SCOOP fairway. Many drilling units here have seen Woodford horizontal development, often with multiple wells per unit. The area has both modern horizontal activity and substantial legacy vertical production from decades past.
Activity: High Development: SCOOP active
Eastern Stephens / Garvin Border
T1N-T2S R4W-R6W
Eastern Stephens transitions toward Garvin County, where SCOOP activity has been heaviest historically. The Woodford and Springer fairway runs strong through this area. Operators drill across the county boundary as a matter of course, and many units span both counties.
Activity: High Development: SCOOP core
Healdton Field Area
T3S-T4S R3W-R4W
The southwestern corner of the county includes the historic Healdton field, which began producing in 1913 and remains one of the great early Oklahoma discoveries. The character here is heavily conventional, with thousands of legacy wells and shallow production zones. Modern horizontal activity is more selective.
Activity: Legacy + Selective Development: Mature conventional
Northwestern Stephens
T1N-T2N R9W-R10W
Northwestern Stephens transitions toward Comanche County and the southwestern margin of the Anadarko Basin. SCOOP activity thins as the Woodford fairway weakens westward, but conventional production continues. Cement field, partially in this area, has a long history.
Activity: Moderate to Light Development: Selective
Southern Stephens / Carter Border
T3S-T4S R5W-R7W
Southern Stephens transitions toward Carter County and the Ardmore Basin. The geological character shifts somewhat, with both SCOOP exposure and legacy conventional zones. Operators drill across the county boundary, and units may span both counties.
Activity: Moderate Development: Mixed
Marlow / Velma Area
T2N-T2S R7W-R8W
The Marlow and Velma areas in central Stephens have long-standing conventional production with overlay horizontal development. Velma field is one of the older Stephens County producers and continues to generate modest royalty income for many mineral families.
Activity: Moderate Development: Mixed legacy and modern
05 Your Valuation

What your Stephens County
mineral rights are worth.

Valuation in Stephens County reflects the layered character of the county. Modern SCOOP horizontal inventory supports strong multiples in the core fairway. Legacy conventional production supports steady cash-flow-based valuation. Many tracts carry both. The scenarios below cover what we see most often.

01
Producing Minerals with SCOOP Horizontals
Valued on cash flow plus remaining inventory
If your Stephens County minerals are producing from SCOOP Woodford horizontals, valuation typically starts with trailing royalty income. A buyer applies a multiple based on expected well life, remaining undrilled Woodford and Springer locations, the operator's development pace, and commodity outlook. SCOOP multiples reflect the relatively predictable horizontal economics and the meaningful stacked-pay inventory.
What shapes the number: well vintage and remaining life on producing horizontals, count of undrilled Woodford and Springer locations in the unit, your royalty rate, the operator, and lease cost-deduction language.
02
Legacy Vertical Production Only
Valued on cash flow plus horizontal optionality
Many Stephens County mineral interests have only legacy vertical wells producing, often from zones like the Hunton, Sycamore, or shallower sands. These checks may be modest but consistent. Valuation here considers both the current cash flow and the underlying optionality on Woodford or Springer horizontal development at deeper depths. The deep rights are often the bigger component of value even when surface activity is quiet.
What shapes the number: current royalty stub amounts, expected legacy well decline, whether the deep rights are leased or open, and SCOOP fairway position beneath your specific tract.
03
Unleased Minerals in the SCOOP Fairway
Valued on lease bonus and drilling proximity
Unleased Stephens County minerals in the SCOOP fairway can carry meaningful value through lease bonus negotiations plus future royalty potential. Operators competing for acreage in the core fairway support lease bonus levels and royalty rates above what older legacy leases carry. Unleased minerals also retain full optionality on operator selection and lease terms.
What shapes the number: nearby permit activity, the dominant operator's drilling pace in your township, Woodford quality beneath your section, comparable lease bonuses on surrounding tracts, and Oklahoma pooling dynamics.
04
Small Fractional Inherited Interests
Often worth more than expected
Many Stephens County mineral families have held interests across three or four generations, with the original interest now divided across many cousins. Even small fractions can carry real value when the underlying acreage is in the SCOOP fairway or has consistent legacy production. We pay these interests the same attention as larger ones and handle the title research, including chains that go back to original allotments or homestead patents.
What shapes the number: net mineral acre count, royalty rate if leased, producing status, accumulated unpaid suspense (sometimes meaningful for older interests where the operator has lost contact with heirs), and whether other heirs are also active.

06 The Regulatory Landscape

Oklahoma rules,
SCOOP realities.

Stephens County operates under the Oklahoma oil and gas regime, administered primarily by the Oklahoma Corporation Commission. Oklahoma has a long and well-developed body of statutes and case law around mineral rights, leasing, pooling, and royalty payment, reflecting its century-plus history as an oil and gas state.

The Corporation Commission and spacing

The Oklahoma Corporation Commission (OCC) Oil and Gas Conservation Division regulates well permitting, spacing, pooling, and production reporting in Stephens County. Drilling and spacing units in Oklahoma are established by Commission order. Traditional spacing patterns of 640 acre sections are common, but modern horizontal development frequently uses multi-section units to support longer laterals. Pooling orders, which compel unleased interests to participate, are issued through formal Commission proceedings.

Forced pooling and your options

Oklahoma's forced pooling statute allows operators to apply for an order pooling unleased interests within a drilling unit. The Commission issues a pooling order specifying bonus and royalty options the unleased owner can elect. Owners must elect within a set time, typically twenty days from the date of the order. If you receive a pooling notice and do not respond, you may be deemed to have elected a default option, often the lowest bonus with a fixed royalty. Pooling notices are real deadlines worth taking seriously.

The Production Revenue Standards Act and payment timing

Oklahoma's Production Revenue Standards Act (PRSA) sets timelines and interest requirements for royalty payment. First royalty payment generally must be made within six months of first sales, and subsequent payments within sixty days of the production month. Suspended payments accrue interest under specified terms. If you have minerals where royalty payments are stuck in suspense, the PRSA framework provides remedies.

Cost deductions and lease language

Whether post-production costs (gathering, compression, treating, dehydration, transportation) can be deducted from your royalty depends substantially on your lease language. Oklahoma case law on this topic has been active, with several appellate decisions over the past two decades shaping the framework. Some leases are explicitly cost-free for the royalty owner. Others permit certain deductions. Reading your lease carefully matters.

07 Questions We Hear Often

The real questions
mineral owners ask.

We have been through these conversations many times. Below are honest answers to the things people actually want to know.

01
How much are mineral rights worth in Stephens County, Oklahoma?
Stephens County values depend on a lot of variables: where in the county you sit, whether you are in the heart of the SCOOP fairway or in legacy shallow production country, whether the minerals are leased or producing, the operator, your royalty rate, and the lease cost-deduction language. The SCOOP play has supported strong valuations in the core fairway, but Stephens County has a long history of conventional production too, and the legacy zones still matter. The honest answer is that we need to look at your specific tract to give you a real number. We are happy to do that for free.
02
What is the SCOOP play and how does it affect my Stephens County minerals?
SCOOP stands for South Central Oklahoma Oil Province. It is the horizontal play targeting the Woodford and Springer formations across Stephens, Garvin, Grady, and Carter counties. The play was unlocked by Continental Resources around 2012 and has been the primary driver of modern drilling in the county. If your minerals are in the SCOOP fairway, you may see operators drilling multi-well horizontal pads with laterals of one to two miles. The development pattern is meaningfully different from the old vertical wells your family may remember.
03
I inherited mineral rights in Stephens County but I don't have any documents. What do I do?
This is one of the most common situations we see. Stephens County has been producing oil for over a hundred years, and many interests have passed through three or four generations. Start with anything you do have: old letters from operators, royalty stubs, probate records, tax statements, division orders. The Stephens County Clerk's office in Duncan keeps deed records. The Oklahoma Corporation Commission maintains public well and operator records. We can usually identify what someone owns with a name and a general idea of where the minerals are located. Oklahoma records are publicly accessible.
04
Should I sell my Stephens County mineral rights now or hold them?
It depends on your situation. People who hold typically want the long-term royalty income, do not need cash for other priorities, and are comfortable with commodity price swings. People who sell typically want to convert uncertain future income into certain present value, simplify their estate, or use the capital for something else. Stephens County has both the SCOOP horizontal inventory and legacy conventional production, which means both the holding case and the sale case can be reasonable. Neither is wrong. We can help you think through the tradeoffs.
05
My family has been getting small royalty checks for decades from old vertical wells. Is that worth anything?
Often yes, more than people expect. Stephens County has a long conventional history, and many families receive checks from wells drilled in the 1950s, 60s, or 70s. Those small checks reflect current production from older wells, but the same mineral interest may also have undeveloped SCOOP potential underneath. Two layers of value: the legacy production and the deeper horizontal inventory. We are happy to look at what you have and explain both pieces.
06
What is forced pooling in Oklahoma and does it affect me?
Oklahoma allows operators to apply to the Corporation Commission to pool unleased mineral interests within a drilling unit. The unleased owner is given options, typically a few bonus and royalty election alternatives, and must elect within a set period. If you receive a pooling notice and do not respond, you may be deemed to have elected a default option. Pooling notices are real legal deadlines and worth paying attention to. We can help explain what a pooling order actually means for your interest.
07
Can I sell mineral rights I inherited if other family members inherited the same minerals?
Yes. You can sell your undivided fractional interest without involving the other heirs. This is extremely common in Stephens County, where interests have been divided across many generations. A good buyer will work with whatever fraction you own and will not require you to round up cousins or run probates the rest of the family has not gotten around to. We do this all the time.
08
My royalty statements have cost deductions. Is that normal in Oklahoma?
Whether post-production costs can be deducted in Oklahoma depends substantially on your specific lease language. Oklahoma case law on this topic has been active and continues to evolve. Some leases are 'cost-free' for the royalty owner, others permit gathering, compression, treating, and transportation deductions. Reading your lease carefully matters. We can help review your statements and lease together if that would be useful.
09
How does the sale process actually work?
Step one, we do the research. You send us what you have, we pull OCC records, check operator activity, and build an analysis. Step two, we send you a written summary with our reasoning. 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 at your pace, fast or slow. 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 Texas and Montana. We work across the primary US basins and we are comfortable with Oklahoma SCOOP and conventional specifics including OCC pooling procedure, PRSA payment rules, and the long history of legacy production in Stephens County. We work with mineral interests of all sizes, including small fractional positions inherited across generations. Our process is straightforward: we research the tract, share what we find, make an offer. The decision is yours.
