In 1900, on the eve of the historic Spindletop oil boom, Texas property law faced an unprecedented challenge: who owns fluid wealth that flows beneath property lines? To resolve disputes over subterranean oil reservoirs, Texas courts adapted an ancient English common law doctrine known as the rule of capture, originally developed for wild animals like foxes and deer. Under this principle, migratory wild animals belonged to no one until captured; similarly, fugacious subsurface minerals like oil and gas belonged to whichever property owner brought them to the surface.
If a landowner drilled a well on their property and drained oil that had originally rested beneath a neighbor's adjacent land, the neighbor had no legal claim for trespass or theft. The neighbor's sole legal remedy was to drill their own well as quickly as possible—effectively encouraging a high-stakes race to drain the shared reservoir before others did. This legal doctrine created chaotic field conditions in early 1900s Texas.
Landowners crowded oil derricks side-by-side along property borders, creating forests of wooden towers and over-drilling fields at reckless speeds. Beyond economic waste, this race ruined underground pressure dynamics, trapping millions of barrels of oil permanently in the rock strata. It was not until decades later, through the creation of the Texas Railroad Commission's prorationing rules and mandatory spacing requirements, that the state managed to curb the destructive incentives inherent in the raw rule of capture.
