01 The Basin

The Marcellus dry gas core,
concentrated in one county.

The Appalachian Basin spans parts of Pennsylvania, West Virginia, Ohio, and New York, but the most productive part of the modern Marcellus play sits in a tight cluster of counties in southwestern Pennsylvania and northern West Virginia. Greene County is the most productive of those counties, and has been for years.

According to data from the Pennsylvania Department of Environmental Protection, Greene County is consistently the top natural gas producing county in Pennsylvania, and Pennsylvania is consistently the second-largest gas-producing state in the country behind only Texas. The county sits squarely in the dry gas window of the Marcellus Shale, where the rock has cooked long enough to produce almost entirely methane with very little associated liquids. Wells here typically have some of the highest initial production rates and longest economic lives in the entire basin.

If you want to know what a mature dry gas Marcellus position looks like in steady-state, look at Greene. This is the play the rest of the basin compares itself to.

If you are reading this, you probably own a piece of that. Maybe it came through a will, a letter showed up in the mail with an offer to lease, or you are trying to make sense of a royalty statement that started arriving years ago. This page is for you. Below we walk through the rock, who is drilling, where in the county your minerals sit, what shapes value, and how the regulatory side actually works.

02 The Rock

Two formations. One stacked column.
Dry gas across the section.

Greene County's productive geology is anchored by two unconventional reservoirs stacked thousands of feet apart: the shallower Marcellus Shale and the deeper Utica Shale. The Marcellus is the workhorse, but Utica rights are increasingly meaningful for long-term value. Most modern leases in the county cover both formations even where only one has been drilled.

Marcellus ShaleDevonian black shale

The Marcellus is the primary target throughout Greene County and the formation responsible for the bulk of current production. It sits at roughly 6,500 to 8,000 feet below the surface in this part of southwestern Pennsylvania, with thickness generally in the 50 to 150 foot range. The rock is rich in organic content and sits squarely in the dry gas thermal maturity window, meaning wells produce nearly pure methane with very little associated liquids.

For mineral owners, the Marcellus is almost certainly the formation being produced under your tract if you currently receive royalties. Modern Marcellus wells in Greene County have some of the highest initial production rates in the basin, and even older wells from the early 2010s continue to produce meaningful volumes.

Below the Marcellus sits the Utica Shale, a separate and significantly deeper organic-rich shale interval. Under Greene County, the Utica generally sits at 11,000 to 13,000 feet, several thousand feet below the Marcellus. The Utica has been tested in the county with results that vary by location. Drilling costs are higher because of the depth, but the formation contains substantial gas-in-place and remains a credible secondary target.

For Greene County mineral owners, the Utica is the reason a tract with established Marcellus production can still carry meaningful undeveloped upside. Many leases cover both formations, and operators have generally held onto Utica rights even when only the Marcellus is being actively developed.

Sitting just above the Marcellus is a series of Upper Devonian shale intervals, including the Burket (sometimes called the Geneseo). The Burket has been tested in parts of southwestern Pennsylvania as a secondary target, generally with modest results compared to the Marcellus. It is rarely the primary target on a new well but occasionally appears in operator inventory discussions.

The practical implication for mineral owners is that even mature Greene County tracts often have stacked pay potential beyond the formation currently producing. Most modern leases include language that covers all depths and all formations, which protects long-term optionality.

03 The Operators

Who is drilling on your
Greene County minerals.

Greene County's operator landscape is dominated by a small number of large public producers. The Marcellus saw substantial consolidation through the late 2010s and into the 2020s, and the operators below cover the bulk of current drilling and royalty activity, though smaller operators still hold pieces of the county.

i.
EQT Corporation
EQT is the largest natural gas producer in the United States and the dominant operator in Greene County. Headquartered in Pittsburgh, EQT has built its position through years of organic drilling and through major acquisitions including Rice Energy in 2017 and Tug Hill in 2023. The company has emphasized long-lateral development and combo development of contiguous acreage blocks. Mineral owners with EQT leases typically see steady, predictable development activity.

CNX Resources
CNX is another Pittsburgh-based pure-play Appalachian operator and one of the longest-tenured natural gas producers in the region. The company was spun out of the legacy CONSOL Energy coal business and retains substantial acreage across southwestern Pennsylvania. CNX has been a steady, methodical developer in Greene County and is known for its long-term focus on free cash flow rather than aggressive volume growth.

Range Resources
Range Resources is widely credited with drilling the first commercial Marcellus horizontal well in Pennsylvania, in nearby Washington County in 2004. The company holds substantial acreage in southwestern Pennsylvania, including parts of Greene County, with a position weighted slightly toward the wet gas window in adjacent counties but with meaningful dry gas inventory in Greene. Range is known for tight operational execution.

Other Producers & Long Tail
Greene County has a long tail of smaller operators and legacy producers, some of whom hold tracts that were drilled in the early Marcellus era and have since changed hands. Mineral owners may also encounter older shallow conventional operators of record on legacy wells. Operator names on division orders sometimes lag the actual ownership of the working interest, so it is worth checking the current operator with the DEP database if you are uncertain.

04 The Geography

Not all Greene County
minerals are built the same.

Greene County covers about 576 square miles in the southwestern corner of Pennsylvania, bordered by West Virginia to the south and west and Washington County to the north. The dry gas Marcellus window runs through essentially the entire county, but operator concentration, surface conditions, and remaining inventory vary by township.

Waynesburg Core
Central Greene County Seat
The geographic and operational heart of the county, centered on the borough of Waynesburg. Tracts in this area have seen sustained development over the past decade. Remaining Marcellus inventory is meaningful in many sections, and the area is generally considered the most predictable part of the county for both drilling activity and royalty income.
Activity: Highest Development: Mature, infill
Northern Greene / Washington Border
Morris · Center Richhill Townships
The northern tier of the county runs up to Washington County and includes some of the earliest Marcellus development in southwestern Pennsylvania. EQT and CNX both have substantial positions here. Long-lateral development is common, and a number of pads in this area host six or more wells targeting the Marcellus.
Activity: High Development: Active
Southern Greene / WV Border
Wayne · Gilmore Aleppo Townships
Southern Greene runs to the West Virginia state line. Operators here include EQT and several West Virginia-focused producers whose acreage straddles the border. Drilling activity has been steady, with units sometimes crossing state lines, which can complicate but not prevent development.
Activity: Moderate to High Development: Active
Eastern Greene / Monongahela Corridor
Cumberland · Monongahela Greene Townships
The eastern part of the county slopes down toward the Monongahela River. This area has historically seen heavy coal mining, which means many tracts have severed estates with coal, oil and gas, and surface owned by different parties. Title work here often requires care, but development activity has been steady where the gas estate is intact.
Activity: Moderate Development: Title-sensitive
Western Greene
Springhill · Gilmore Jackson Townships
The western edge of the county is rural and rugged, with development pace generally a step behind the central core. Operators have continued to add inventory here through longer laterals and combo development. Many tracts in this area carry undeveloped Utica potential in addition to current Marcellus production.
Activity: Moderate Development: Selective
Coal Estate Areas
Various County-wide
Many tracts across Greene County have severed coal estates, often owned by entities completely separate from the surface or oil and gas owners. This does not prevent gas development but it does mean title work is more involved and surface use agreements sometimes require more negotiation. Mineral owners in these areas can still receive royalties, the title chain is just longer.
Activity: Variable Development: Title-sensitive
05 Your Valuation

What your Greene County
mineral rights are worth.

There is no universal formula. Valuation in Greene County is shaped by current production, future drilling inventory, operator quality, lease terms, and natural gas prices. Greene's distinguishing feature is that even mature tracts typically have meaningful inventory left, particularly when you factor in undeveloped Utica rights. What follows are the four scenarios we see most often.

01
Producing Minerals with Active Royalty Income
Valued on cash flow plus remaining inventory
If your Greene County minerals are actively producing and you receive monthly royalty checks, 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 on the tract, and gas price outlook. Greene County tracts often carry stronger multiples than other Marcellus counties because the dry gas window here supports long well lives and remaining inventory expectations are higher.
What shapes the number: well vintage and remaining productive life, how many additional Marcellus or Utica locations remain undrilled on your tract, your royalty rate, the operator quality, and whether your lease permits post-production cost deductions for gathering, compression, and processing.
02
Unleased Minerals in Active Development
Valued on drilling proximity and future potential
Unleased Greene County minerals, particularly in the northern and central townships, are valued on expected development timing and operator activity within a few miles. Buyers look at recent permits, operator acreage positions, and the trajectory of drilling within a township. Unleased minerals also carry optionality because the buyer can negotiate lease terms directly with the operator.
What shapes the number: nearby permit activity, the operator's recent drilling pace in your township, formation quality beneath your specific tract, comparable lease bonuses paid on surrounding tracts, and whether the area is targeted for near-term combo development.
03
Small Fractional Interests & Inherited Positions
Often overlooked, often worth more than expected
Many Greene County mineral owners hold small fractional interests inherited across multiple generations, often spread across heirs in different states. These positions sometimes get ignored by larger buyers because they are administratively cumbersome. We pay them the same attention as larger interests and we are comfortable doing the title research on fractional chains, including positions that trace back to severed coal and gas estates from the early 1900s.
What shapes the number: net acre count, royalty rate if leased, producing status, operator quality, remaining drilling inventory on the tract, and whether other heirs holding the same chain are also ready to move.
04
Leased but Not Yet Producing
Valued on lease terms and proximity to activity
If your minerals are leased but not yet producing, value depends on the lease terms and how close active drilling has moved toward your acreage. Pennsylvania leases typically have five year primary terms with extension if held by production. A lease held by a major active driller such as EQT or CNX 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 units, and whether your lease has a Pugh clause, post-production cost protections, or similar acreage-protection language.

06 The Regulatory Landscape

Pennsylvania rules,
Marcellus realities.

Greene County operates under Pennsylvania's oil and gas regulatory regime, administered primarily by the Pennsylvania Department of Environmental Protection. The on-the-ground realities reflect Pennsylvania's distinctive legal history around severed estates, the absence of compulsory pooling for Marcellus, and the practical effects of southwestern Pennsylvania having been actively drilled, mined, and developed for well over a century.

The DEP and the Bureau of Oil and Gas Management

The Pennsylvania Department of Environmental Protection, through its Bureau of Oil and Gas Management, regulates oil and gas activity in Greene County. The DEP permits wells, regulates surface activity and water use, and maintains the public well database. Production reporting is done through the DEP and is publicly available. Unlike some other producing states, Pennsylvania does not have a single industrial commission that handles pooling and unitization disputes; those are largely contractual matters governed by individual leases.

Pooling, unitization, and the absence of compulsory pooling

Pennsylvania law does not provide for compulsory pooling of Marcellus minerals. This is a meaningful distinction from states like North Dakota, Texas, and Oklahoma. In practical terms, an operator must obtain a voluntary lease from each mineral owner whose tract is included in a unit. If a mineral owner refuses to lease, the operator generally cannot force participation. The Pennsylvania Supreme Court's interpretations of the older 1961 conservation law have generally not extended compulsory pooling to the Marcellus. The practical result is that unleased Greene County mineral owners typically retain meaningful negotiating leverage.

Severed estates and the coal, oil, gas, surface separation

Pennsylvania has one of the longest histories of severed mineral estates in the country. In Greene County, it is common to find tracts where the coal estate, the oil and gas estate, and the surface are owned by three different parties. The Dunham Rule, a longstanding Pennsylvania doctrine, generally holds that a reservation of "minerals" in a deed does not include oil and gas unless specifically stated. This is one of many reasons why title research is sometimes the most important part of a Greene County mineral analysis.

Pennsylvania's Guaranteed Minimum Royalty Act

Pennsylvania law requires that mineral lessors receive a royalty of at least 12.5 percent (one-eighth) on production. Many modern leases in Greene County provide royalty rates above the statutory minimum, often in the 15 to 20 percent range, particularly in areas where competitive leasing activity has been strong. The treatment of post-production deductions remains an active area of litigation in Pennsylvania, and the specific language of your lease matters significantly.

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.

01
How much are mineral rights worth in Greene County, Pennsylvania?
Values in Greene County vary widely depending on where in the county you own, whether your minerals are leased or producing, who the operator is, and how much remaining drilling inventory exists on your tract. Greene County minerals tend to carry stronger valuations than most other Marcellus counties because the dry gas window here is among the most productive in the entire Appalachian Basin, but the same interest can have a meaningfully different value from one township to the next. 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
What is the difference between the Marcellus and the Utica under Greene County?
The Marcellus Shale sits at roughly 6,500 to 8,000 feet under Greene County and is the primary producing formation. The Utica Shale sits several thousand feet deeper, generally in the 11,000 to 13,000 foot range, and has been tested in Greene County with mixed results. Most current drilling targets the Marcellus because the economics are well established. Some operators retain Utica rights under their existing Marcellus leases, which means a single lease can cover both formations even if only the Marcellus has been drilled.
03
I inherited mineral rights in Greene 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 Greene County Recorder of Deeds in Waynesburg keeps deed records, and the Pennsylvania DEP maintains a public database of wells and permits. We can usually identify what someone owns with just a name and a rough idea of where the minerals are located, because Pennsylvania mineral records are publicly accessible when you know where to look.
04
Do I own the gas rights if I own the surface in Greene County?
Not necessarily. Pennsylvania has a long history of severed mineral estates, particularly in the southwestern counties. Many surface tracts in Greene County had their oil and gas rights separated from the surface decades or even a century ago, often during the early coal and gas era. The deed history is what matters. A title search can tell you whether the gas rights traveled with the surface or were severed and conveyed separately. We do this kind of research regularly.
05
Should I sell my Greene 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 natural gas price volatility. People who sell typically want to convert future uncertain income into certain present value, simplify their estate, or use the capital for something else. Neither is wrong. The Marcellus is a mature play with predictable behavior, which makes both holding and selling defensible strategies depending on your goals. We can help you think through the tradeoffs without pressure to pick a side.
06
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 five years in Pennsylvania, with extension if production is established. In exchange you receive a bonus payment per net 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. Buying typically delivers more value up front, leasing preserves long-term upside.
07
Why are my royalty checks smaller than I expected?
There are a few common reasons. First, natural gas prices in the Appalachian Basin have historically traded at a discount to the national Henry Hub benchmark because of pipeline takeaway constraints out of the region. Second, many Pennsylvania leases allow operators to deduct post-production costs, things like gathering, compression, processing, and transportation, before calculating your royalty. Third, the well decline curve in shale is steep, so production drops quickly after the first year or two. Reviewing your lease language and royalty statement can usually explain the gap between expectations and reality.
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 common in Greene 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 DEP and county records, we check operator activity in your area, and we build an analysis. Step two, we send you a written summary with our reasoning. Step three, if you want to proceed, we handle the deed preparation, you sign at a notary, and funds are wired at close. We move on your timeline, whether that is quick or deliberate. 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 but we spend most of our time in the Powder River Basin, the DJ Basin, the Williston Basin, and the Appalachian Basin. That means we know Greene County geology, the operators working here, and how Pennsylvania handles things. We work with mineral interests of all sizes. Our process is straightforward: we research the tract, share what we find, and make an offer. The decision to sell is yours, and we are happy to help you understand what you have either way.
