A Greene County family finds a deed from 1902 in which a great-grandfather sold “all the coal and other minerals” under the farm, and reasonably concludes there is nothing left to own. Very often that conclusion is wrong. Under Pennsylvania law the word minerals in an old deed usually did not carry the oil and gas with it, which means the Marcellus beneath that farm may still belong to the family that thinks it sold everything a century ago.
Greene County is where this matters most, because Greene was sold twice: for coal in the first years of the twentieth century, when the Pittsburgh seam was the most valuable thing under southwestern Pennsylvania, and again for gas a hundred years later. Those sales were made by different people, in different centuries, using different words, and Pennsylvania law treats them differently. Neighboring Washington County carries the same double history. Across the state line the same Marcellus runs under Monongalia and Wetzel counties in West Virginia, where the law is not the same at all. And the case that settled the question for the whole of Pennsylvania came from a farm in Susquehanna County, at the opposite corner of the state, far from the coal country of the southwest.

One Tract, Three Estates, Three Different Owners
In Pennsylvania a single parcel can be split into separate estates that are bought and sold independently: the surface, the coal, and the oil and gas. A Greene County farm can easily have three different owners stacked on top of one another, none of whom has met the others. The surface may be farmed by a family who bought it in the 1970s, the coal may sit with a mining company through a chain of assignments going back to 1905, and the gas may still be held, unknowingly, by the scattered heirs of whoever signed that first deed.
The stakes are no longer theoretical. Greene is one of only four Pennsylvania counties that produced more than a trillion cubic feet of gas in 2025, at roughly 1.14 Tcf, alongside Susquehanna, Bradford and Washington, according to FracTracker’s analysis of state production data. An interest that was worth nothing for ninety years is now worth finding out about.
The Dunham Rule: In Pennsylvania, Minerals Usually Does Not Mean Gas
Pennsylvania has a rule that surprises people from every other producing state. Since Dunham v. Kirkpatrick in 1882, the courts have applied a rebuttable presumption that where a deed reserves or excepts minerals without specifically naming oil or natural gas, the parties did not intend to include them. The reasoning is that ordinary people in the nineteenth century, speaking plainly rather than scientifically, did not think of gas when they said minerals. They thought of coal, and of things you could dig.
The presumption can be defeated, but not easily. Anyone arguing an old minerals reservation did capture the gas must show by clear and convincing evidence that the parties intended it at the time. That is a demanding standard, and it is why so many Pennsylvania mineral owners turn out to hold gas rights they assumed were gone.
Butler, an 1881 Deed, and 244 Acres
For a few years it looked as though the Marcellus might be an exception. In Butler v. Charles Powers Estate, a 244-acre Susquehanna County tract was subject to an 1881 deed reserving “one-half [of] the minerals and Petroleum Oils.” The Superior Court decided the question needed expert evidence on whether shale gas was different in kind. That reasoning, had it stood, would have reopened tens of thousands of Pennsylvania deeds.
On April 24, 2013 the Supreme Court reversed, holding that under the Dunham Rule the trial court had been right on the face of the deed and that Marcellus gas was not contemplated by that 1881 reservation. The rule survived intact and plainly covers shale gas. For a Greene County owner the translation is short: if the old instrument says minerals and does not say gas or oil, the starting presumption is that the gas stayed behind.

Where the Coal Changes the Answer
Coal country adds a wrinkle that rarely arises in the dry gas counties to the northeast. In United States Steel Corp. v. Hoge, decided in 1983 on a 1920 severance deed conveying all of the coal together with the right of ventilation, the Pennsylvania Supreme Court quieted title to the coal seam methane in the coal owner. Gas present within the coal, the court reasoned, belongs to whoever owns the coal for as long as it remains there and subject to that owner’s control. The decision has been picked over by commentators ever since, but it remains the Pennsylvania starting point for coalbed gas.
Hold the two cases side by side and the Greene County position comes into focus. Gas inside the Pittsburgh seam most likely went with the coal. Gas in the Marcellus, thousands of feet below it, is a different estate entirely, and an old coal or minerals deed that never said gas very likely did not take it. That distinction is the most valuable thing a Greene County owner can understand about their own paperwork.
How to Get the Best Price for Oil and Gas Rights in Greene County
Anyone making you a serious offer runs the chain of title first, which in Greene County means reading century-old coal instruments as carefully as recent leases. Three questions decide the price. Does the severing deed name gas, or only minerals? Is the interest in the Marcellus or arguably in the coal seam? And is the chain clean enough to write a title opinion without litigation?
This is why quoting a per-acre figure before reading the deeds is guesswork. Two Greene County tracts with identical acreage and geology can be worth materially different amounts because one 1902 deed said “coal, oil and gas” and the neighbor’s said “coal and other minerals.” Where the chain is ambiguous but curable, resolving it before going to market normally returns more than it costs, because a buyer prices uncertainty into the offer far more harshly than the cost of clearing it. We do that title work ourselves, at our expense, which is how we get to the best price for mineral rights rather than discounting for risk we could simply have checked.

Checking Your Own Chain
- Start with the severing instrument. Deeds are recorded with the Greene County Recorder of Deeds in Waynesburg. You want the document that first split the estates, and its exact wording.
- Read the words, not the summary. Minerals alone, or coal and other minerals, points one way. An express reference to gas points the other. The difference is a few words and, quite possibly, six figures.
- Separate coal from Marcellus. Establish which seam or formation a reservation was actually about before assuming it swept up everything below.
- Look for later leases and division orders. If an operator has already paid someone on that tract, the paperwork shows who they concluded owned it – useful, though not binding.
This is background, not legal advice, and a Pennsylvania oil and gas title attorney is the right person to give you an answer you can rely on. On an interest of any size, that opinion is inexpensive next to what it settles.
