The rule of capture or law of capture, part of English common law and adopted by a number of
U.S. states

groundwater
Groundwater is the water present beneath Earth's surface in rock and Pore space in soil, soil pore spaces and in the fractures of stratum, rock formations. About 30 percent of all readily available fresh water in the world is groundwater. A unit ...

oil
An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobic (does not mix with water) and lipophilic (mixes with other oils). Oils are usually flammable and surface active. Most oils are unsaturate ...

Gas is a state of matter that has neither a fixed volume nor a fixed shape and is a compressible fluid. A ''pure gas'' is made up of individual atoms (e.g. a noble gas like neon) or molecules of either a single type of atom ( elements such as ...

game animals. The general rule is that the first person to "capture" such a resource owns that resource. For example, landowners who extract or “capture” groundwater, oil, or gas from a well that bottoms within the subsurface of their land acquire absolute ownership of the substance even if it is drained from the subsurface of another’s land. The landowner who captures the substance owes no duty of care to other landowners. For example, a water well owner may dry up wells owned by adjacent landowners without fear of liability unless the groundwater was withdrawn for malicious purposes, the groundwater was not put to a beneficial use without waste, or (in Texas) "such conduct is a proximate cause of the subsidence of the land of others." An exception to the rule of capture is that a person who drills for groundwater, oil, or gas may not extract the substance from a well that bottoms within the subsurface estate of another by drilling on a slant.
Theories of ownership
When presented with oil and gas cases, early common law jurists were somewhat reluctant to recognize a corporeal possessory interest in substances that they considered to be fugacious or “wild and migratory” and therefore subject to loss by drainage. Among

remedies.
Boundary determination
Subsurface ownership boundaries are the same as those upon the surface, projected downward to the center of the Earth. This concept is based upon a Roman legal principle of
property law
Property law is the area of law that governs the various forms of ownership in real property (land) and personal property. Property refers to legally protected claims to resources, such as land and personal property, including intellectual prope ...

Conservation acts
The rule of capture creates an incentive for owners to drill as many wells as possible on their land so as to extract the groundwater, oil, or gas before their neighbors may capture it. Very dense drilling can result in dissipation of the pressure within an aquifer or oil and gas reservoir and therefore

Overdrafting is the process of extracting groundwater beyond the equilibrium yield of an aquifer. Groundwater is one of the largest sources of fresh water and is found underground. The primary cause of groundwater depletion is the excessive pum ...
of the aquifer or incomplete extraction of the substance. To mitigate that danger, many states have sought to supersede the rule of capture with conservation acts. Such acts enforce prorationing, pooling, and limits on density of drilling to avoid physical waste and ensure maximum ultimate recovery. The means of protecting aquifers from over production include both production limits and well-spacing regulations.
States following the ownership-in-place theory typically have actions available, including adverse possession and trespass.
