Permian Basin (West Texas & Southeast New Mexico)

The Permian Basin covers roughly 86,000 square miles and about 55 counties across West Texas and southeast New Mexico, and it is the largest producing oil basin in the country, supplying roughly 48% of total US oil output as of 2025 (U.S. Energy Information Administration). On the New Mexico side, the basin runs through Lea, Eddy, Chaves, and Roosevelt counties. On the Texas side it centers on the Midland and Delaware sub-basins around hubs like Midland, Odessa, and Loving County. For inspection procurement, that scale translates into a specific operating problem: thousands of well pads, tank batteries, compressor stations, and gas processing sites spread across sparsely populated counties, most of them well outside any metro inspection market. Two states means two regulatory stacks running side by side. On the Texas side, the Railroad Commission of Texas (RRC) holds primary jurisdiction over drilling, production, and oilfield waste handling, while the Texas Commission on Environmental Quality (TCEQ) handles air permitting under Permit by Rule, Standard Permit, or full New Source Review (30 TAC Chapter 116). TCEQ also ran a temporary "Find It and Fix It" compliance initiative in 2020-2021 across the 61 Texas counties it defines as the Permian Basin Geological Area; that specific enforcement-discretion program has since concluded, though TCEQ still uses the 61-county designation for ongoing air monitoring. Cross into Lea or Eddy County, New Mexico, and jurisdiction shifts to the state's Oil Conservation Division for well operations and to the New Mexico Environment Department for air quality, including a 2021 gas-capture rule requiring operators to capture 98% of produced natural gas by 2026 and an Ozone Precursor Pollutants rule (20.2.50 NMAC) that covers Eddy and Lea counties along with Chaves County and several other New Mexico counties outside the basin. A vendor who knows TCEQ paperwork cold on a Midland County job is not automatically current on New Mexico's separate methane-waste reporting a few miles away, so it is worth confirming a vendor's actual field history in each state rather than assuming the two sides of the line run the same playbook. The same line runs through pressure equipment law and safety enforcement. Texas regulates boilers and unfired steam boilers through the Texas Department of Licensing and Regulation (TDLR) under the Texas Boiler Law, Health and Safety Code Chapter 755, with inspection intervals that vary by boiler class. New Mexico's Mechanical Bureau inspects boilers and pressure vessels under Title 14, Chapter 9 of the state administrative code, referencing the National Board Inspection Code, a separate registration path from TDLR entirely. Workplace safety enforcement splits the same way: Texas has no OSHA-approved state plan for private employers, so federal OSHA enforces directly, while New Mexico runs its own OSHA State Plan through its Environment Department's Occupational Health and Safety Bureau. None of this changes the underlying ASME or API code a piece of equipment is built and inspected to, but it does change who shows up if a citation is issued, and which agency's paperwork a vendor needs to already understand. Three vendor categories carry outsized weight in this basin. Pressure vessel inspection specialists matter because separators, treaters, gas processing vessels, and produced-water tank batteries run under API 510 (in-service pressure vessel inspection), API 570 (piping), and API 653 (aboveground storage tank) codes, layered on top of whichever state boiler law applies to any steam-generating equipment on site. Explosive atmosphere and hazardous-area consulting matters because nearly every well pad, tank battery, and gas plant contains a Class I hazardous location under NEC (NFPA 70) Article 500, and the region's mix of domestic and internationally sourced equipment means buyers increasingly need vendors who can work across both the domestic Division system (API RP 500) and the Zone-based system (API RP 505) more common on ATEX- or IECEx-rated gear. Drone inspection service providers matter because of the terrain itself: GE-backed Avitas Systems and Shell secured a landmark FAA beyond-visual-line-of-sight (BVLOS) waiver in 2018 to fly radar-equipped drones over Permian well pads in Loving County, Texas, and that same problem, pads and pipeline right-of-way separated by miles of caliche road, is what makes drone survey economics work here in the first place.

Regulatory & jurisdictional notes

Railroad Commission of Texas (RRC)

Holds primary regulatory jurisdiction over drilling, production, and oilfield waste handling for wells on the Texas side of the basin, tracing back to the 1919 Oil and Gas Conservation Law. Air quality is handled separately by TCEQ, not RRC.

Texas Commission on Environmental Quality (TCEQ)

Issues air authorizations for Texas oil and gas facilities through Permit by Rule, Standard Permit, or New Source Review under 30 TAC Chapter 116. TCEQ also defines a 61-county 'Permian Basin Geological Area' for air-quality purposes and ran a temporary 'Find It and Fix It' enforcement-discretion initiative there in 2020-2021 (notification window closed January 2021); that specific program has concluded, though the 61-county designation is still in current use for monitoring.

New Mexico Oil Conservation Division (EMNRD)

Regulates well operations on the New Mexico side and administers the state's 2021 gas-capture rule (adopted by the Oil Conservation Commission), which requires operators to capture 98% of produced natural gas, no routine venting or flaring, by December 31, 2026.

New Mexico Environment Department

Enforces the Oil and Gas Sector Ozone Precursor Pollutants rule (20.2.50 NMAC, effective August 2022), which currently covers eight New Mexico counties: Eddy, Lea, and Chaves (all three within the Permian Basin) plus Dona Ana, Rio Arriba, Sandoval, San Juan, and Valencia outside it. Requires VOC and NOx monitoring plus leak detection and repair; the county list can expand if other areas trip the ozone threshold.

Texas Department of Licensing and Regulation (TDLR)

Regulates boilers and unfired steam boilers under the Texas Boiler Law, Health and Safety Code Chapter 755, with inspection intervals that vary by boiler class (e.g., annual for power boilers and unfired steam boilers, biennial for heating boilers, triennial for hot water supply boilers). Confirm whether a given vessel falls under TDLR jurisdiction or is inspected instead under API in-service codes.

New Mexico Mechanical Bureau

Inspects boilers and pressure vessels under Title 14, Chapter 9, Part 4 of the New Mexico Administrative Code, referencing the National Board Inspection Code and ASME Boiler and Pressure Vessel Code, a separate registration and inspection path from Texas's TDLR system.

OSHA enforcement

Texas has no OSHA-approved state plan for private employers, so federal OSHA enforces directly. New Mexico runs its own OSHA State Plan through its Environment Department's Occupational Health and Safety Bureau, covering both public and private employers. The enforcement contact differs depending on which side of the state line a facility sits.

Hazardous area classification

US facilities are classified under NEC (NFPA 70) Article 500's Class/Division system, with API RP 500 as petroleum-specific guidance for that system. API RP 505 covers the Zone-based system more common on internationally sourced or ATEX/IECEx-rated equipment; API 500 remains the standard mandated under the NEC for US installations, so confirm which system a vendor is quoting against before comparing bids.

FAA Part 107 / BVLOS

Beyond-visual-line-of-sight drone operations have a track record on Permian assets: Avitas (backed by GE) and Shell secured a landmark FAA BVLOS approval in 2018 to fly radar-equipped drones over well pads in Loving County, Texas. That is a historical precedent, not evidence of a currently active blanket authorization. Industry-wide BVLOS approval rates run low, so confirm a vendor's actual, current waiver status rather than assuming one is in place.
