Every oil and gas lease, and what it produced
$2,812.11 bn of reported production since Jan 1993, across 12,219 operators and 229 counties — plus every permitted pipeline. Search an operator or a county, or browse the leases.
Every lease has a page: the monthly barrels and Mcf the operator reported, the wells drilled on it, and what each month was worth at the benchmark price.
Every figure comes from a Railroad Commission filing, priced with published EIA benchmarks. Nothing is modelled or estimated; where the state has no data, the page says so rather than guessing.
The lease, operator and county pages are static HTML that anyone — and any AI assistant — can read and cite, with the filing behind every figure named on the page.
