A well on the tract next to yours can legally drain oil and gas out from under your land, and you cannot sue anybody for it. That rule is more than a century old, it is still good law in every producing state, and it quietly explains most of what happens to a mineral owner.

You own the minerals under your tract. You do not own any particular molecule until it comes up your pipe. If it comes up somebody else's pipe first, it was theirs. ## Where it came from The rule is borrowed from the law of wild animals. Nineteenth century courts, confronted with a substance that moves underground and does not respect property lines, reached for the closest thing they knew: a deer is nobody's until somebody takes it. The Pennsylvania Supreme Court made the analogy explicit in *Westmoreland & Cambria Natural Gas Co. v. DeWitt* (Pa. 1889), calling oil and gas **fugacious**, and stated the rule squarely in *Barnard v. Monongahela Natural Gas Co.* (Pa. 1907). Ohio reached the same place in *Kelly v. Ohio Oil Co.* (Ohio 1897). Every producing state adopted some version of it. The courts were candid about the reasoning: they had no way to trace what came from where, so they used the only fact that could be proven, which is who brought it to the surface. ## What it means for you, concretely - **Your neighbor's producing well is not a legal wrong,** even if you can watch your own pressure fall. - **"They are draining me" is not a cause of action.** It is an argument for doing something, not a lawsuit. - **Doing nothing is a decision with a cost.** Unleased minerals surrounded by production are minerals being spent, not minerals being saved. - **Your protection is not the courthouse.** It is the state conservation agency, and it works only if you engage with it. This is the single most important thing an unleased mineral owner in an active area can understand. Owners frequently hold out on principle, believing the oil will keep. It will not necessarily keep. It may be produced from a wellbore half a mile away while they wait. ## The limit: correlative rights Pure capture would reward whoever drilled fastest and most wastefully, which is exactly what happened in the early booms: forests of derricks on tiny lots, reservoir pressure destroyed in a few years, and enormous volumes left permanently in the ground. Every producing state responded with conservation law built on **correlative rights**: the principle that each owner in a common source of supply is entitled to a fair opportunity to produce their fair share, and no more. Correlative rights are why the following exist: | Mechanism | What it does | | **Spacing units** | Fixes how much acreage one well may drain, so a single well cannot legally be used to sweep a whole field || **Well location rules** | Keeps wells off the lease line, so a well cannot be sited specifically to drain the neighbor || **Allowables** | Caps production rates, so the fastest producer does not take everyone's share || **Pooling** | Forces all owners in a unit to share proportionally, whether or not they agreed || **Unitization** | Treats a whole reservoir as one operation for secondary and tertiary recovery | Forced pooling is the rule of capture and correlative rights meeting head on. Oklahoma's Corporation Commission can pool an unleased owner into a unit under **52 O.S. § 87.1**, which sounds coercive until you notice the alternative: without it, the operator drills anyway and the holdout gets nothing at all. Pooling is what converts capture into a share. Our [forced pooling page](https://www.berlinroyalties.com/forced-pooling-oklahoma/) walks through the elections and the deadline, which is the part that actually costs owners money. Texas is the opposite arrangement. It is a voluntary pooling state with a compulsory statute, the Mineral Interest Pooling Act, that is narrow and rarely used successfully. A Texas owner surrounded by production has meaningfully less leverage than an Oklahoma owner in the same position. ## Does the rule of capture cover hydraulic fracturing? This is the live modern question, because fracturing deliberately creates fractures that can cross a property line. Is that still capture, or is it a trespass? Texas answered first. In ***Coastal Oil & Gas Corp. v. Garza Energy Trust***, 268 S.W.3d 1 (Tex. 2008), the Texas Supreme Court held that the **rule of capture bars recovery of damages for drainage caused by hydraulic fracturing**. The royalty owners had a remedy available to them, which was to drill their own well, and the Court declined to let them recover for drainage instead. The decision was closely divided and remains one of the most argued-about cases in the field. Pennsylvania looked at it again more recently. In ***Briggs v. Southwestern Energy Production Co.***, 224 A.3d 334 (Pa. 2020), the Pennsylvania Supreme Court declined to create a blanket exception to the rule of capture for fracturing, but was careful to leave open that an actual **physical intrusion** beneath the neighbor's land could still be a trespass, and sent the case back for that question. The practical takeaway has not changed: drainage alone is not a claim. If you believe a wellbore or a stimulation physically entered your tract, that is a different and much harder case, and it needs a lawyer and an engineer, not a letter. ## How this affects what your minerals are worth Directly, and in a way most valuations ignore. An unleased tract inside an area being developed is losing value on a schedule, because reserves under it are being produced by others. An unleased tract in a quiet area is not. Two identical tracts can be worth very different numbers purely because of what the neighbors are doing, and the difference is not visible on any check stub, because a non-producing owner has no check stub. This is also why "I will wait for a better offer" is sound advice in one setting and expensive in another. When we underwrite, offset activity is a line we show you explicitly. See [how minerals are valued](https://www.berlinroyalties.com/mineral-rights-value/) and, just as often, [when not to sell](https://www.berlinroyalties.com/when-not-to-sell/). ## Common questions My neighbor's well is draining my minerals. Can I stop it?Not by suing over the drainage itself. What you can do is act: lease your minerals so you participate in the unit, respond properly to a pooling application if one is filed, or in some circumstances apply to the state agency yourself. In Oklahoma the Corporation Commission is the forum, and the levers are spacing and pooling. In Texas your options are narrower. Either way, the effective response is administrative and prompt, not litigation later. Then what stops an operator from putting a well right on my property line?Well location and setback rules. Every producing state regulates how close to a boundary or lease line a well may be completed, precisely so that the rule of capture cannot be weaponized by drilling on the line. If a proposed location looks calculated to drain across a boundary, that is an objection to raise with the agency at the location exception hearing, not a trespass suit afterward. Does the rule of capture apply to water, or to lithium brine?Groundwater in Texas is governed by its own version of the rule, modified by groundwater conservation districts. Lithium in brine is unsettled and is being worked out separately. Texas confirmed Railroad Commission jurisdiction over brine mining, but has not decided who owns the dissolved lithium. See our [Smackover and lithium brine page](https://www.berlinroyalties.com/basins/smackover-lithium/). If I get force pooled, have I been treated unfairly?Usually not, and the instinct that you have is worth examining. Pooling is what guarantees you a proportionate share of a unit you would otherwise be drained by. What genuinely costs owners money is not the pooling itself but missing the election deadline, which converts a real choice into a default nobody chose for them. That deadline is the thing to focus on. ### Wells showing up around your minerals? Find out what it means. Send us the county and legal description, or just a pooling notice.
