Every Texas oil and gas lease on record

Every Texas oil and gas lease that has reported production to the Railroad Commission — 322,415 of them, arranged by county, by Commission district and by operator. Each lease has its own page: the full monthly production history the operator filed, an Arps decline curve fitted to it, and an estimate of what a royalty interest in the remaining production is worth today.

By Railroad Commission district

The Commission divides the state into twelve districts. Every lease on record sits in exactly one of them, so these lists are complete.

District 02 — 20,785 leases
District 03 — 24,040 leases
