Understanding US Oil Production by State

The United States is the world's largest oil producer, producing approximately 13.4 million barrels per day. Production is concentrated in a handful of states, with the Permian Basin (Texas and New Mexico) alone accounting for over 6 million barrels per day.

OilPriceAPI tracks drilling permits — the leading indicator of future production — across 27 states. New drilling permits signal where operators plan to drill new wells, providing weeks to months of advance notice before production comes online.

Top Producing Basins

  • Permian Basin (TX/NM) — 6+ million bpd, Wolfcamp and Bone Spring formations
  • Bakken (ND/MT) — 1.2 million bpd, Three Forks formation
  • Eagle Ford (TX) — 1.1 million bpd, South Texas
  • Appalachia (PA/WV/OH) — Largest US natural gas basin (Marcellus Shale)
  • Anadarko/SCOOP-STACK (OK) — Mixed oil and gas

Frequently Asked Questions

Texas is the largest oil-producing state, accounting for approximately 43% of US crude oil production. The Permian Basin in West Texas and New Mexico is the most prolific oil-producing region in the world. North Dakota (Bakken) and New Mexico (Delaware Basin) round out the top three.

While over 30 states have some oil and gas production, the majority comes from about 10 states. Texas, North Dakota, New Mexico, Oklahoma, Colorado, Alaska, Wyoming, Louisiana, California, and Pennsylvania account for over 95% of US production.

OilPriceAPI combines state-level production statistics with drilling permits filed at state regulatory agencies (e.g., Texas Railroad Commission, Oklahoma Corporation Commission). Permit coverage spans 27 configured states; well-level production coverage is source-by-source and returned with timestamps so users can verify freshness.

A drilling permit is an authorization from a state regulatory agency allowing an operator to drill a well at a specific location. Permits contain information about the operator, location (latitude/longitude), target formation, well type (horizontal/vertical), and proposed depth.

Refresh cadence varies by state portal and source publication lag. Priority permit states are checked more frequently, other states are checked on scheduled weekly runs, and every record includes source/update fields so customers can judge freshness instead of assuming same-day availability.
