DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Mobile Employer Drug Testing in Midland, Texas
We travel to your oil field service yard, pipeline facility, fleet yard, or job site and administer federally compliant DOT and Non-DOT collections on-site. No clinic. No downtime.
Midland is the corporate headquarters of the Permian Basin oil and gas industry — the most productive oil-producing region in the United States, accounting for roughly 40 percent of total U.S. crude oil output. Pioneer Natural Resources, Diamondback Energy, Coterra Energy, and Colgate Energy are among the publicly traded Permian Basin operators headquartered in Midland, alongside hundreds of oil field service companies, pipeline operators, and contract drilling firms. Pipeline operators in the Midland Basin — including Permian Highway Pipeline, Kinder Morgan's Permian Express system, and Targa Resources — employ PHMSA 49 CFR Part 199 covered employees across a network of gathering lines, transmission pipelines, and processing plants. Midland International Air and Space Port (MAF) serves as a regional aviation hub with charter, corporate, and cargo operations supporting the oil and gas industry. The concentration of FMCSA-regulated oil field service truck fleets, PHMSA-regulated pipeline operators, and Non-DOT company-policy employers in Midland makes this one of the highest-density DOT testing markets in the Permian Basin.
OnSite Employer Testing coordinates mobile drug testing collections at your Midland oil field service yard, pipeline facility, or corporate office. We do not operate a clinic. Review how it works or browse all locations we serve.
Why Midland Employers Need Mobile Testing
Midland's oil field service companies operate truck fleets that are deployed to well sites hours from the city — water haulers, sand haulers, vacuum trucks, wireline units, and hot oil trucks whose CDL drivers are away from Midland for days at a time. Pre-employment testing for a new CDL driver hired on Tuesday needs to happen before he drives to a Reeves County well pad on Wednesday morning. A clinic that opens at 0800 and closes at 1700 cannot serve an oil field hire schedule that runs around the clock and on weekends. Mobile collection at the service yard or the hiring office — on the employer's schedule — is the only model that keeps Permian Basin oil field fleets compliant.
Pipeline operators in the Midland Basin run gathering systems and transmission lines that require round-the-clock field technician patrols. A PHMSA random selection for a pipeline technician working a 14-day rotation in the field cannot be handled by routing that employee to a clinic in Midland between rotations — it needs to happen at the field office or yard. Mobile testing at the pipeline operator's Midland facility or field staging location keeps PHMSA compliance intact without disrupting the rotation schedule.
Program design and compliance obligations remain your responsibility under applicable law — we coordinate the collections.
Industries We Serve in Midland
Oil Field Service Truck Fleets
Midland's oil field service sector employs thousands of CDL drivers operating water haulers, sand haulers, vacuum trucks, hot oil units, and fluid transport vehicles under FMCSA 49 CFR Part 382. Companies including Basic Energy Services, Select Water Solutions, ProPetro Holding, and dozens of regional operators maintain pre-employment, random, and post-accident programs for their Midland-area CDL fleets. We coordinate logistics and transportation collections at service company yards, dispatch terminals, and hiring facilities throughout Midland County — timed to shift start and crew rotation schedules.
Pipeline and Midstream Operators
Permian Basin pipeline operators including Kinder Morgan, Targa Resources, MPLX, and Energy Transfer operate gathering, processing, and transmission infrastructure throughout the Midland Basin. PHMSA 49 CFR Part 199 anti-drug and alcohol misuse prevention requirements apply to covered pipeline employees — field technicians, compressor station operators, and control room personnel. We coordinate PHMSA-compliant energy and utilities collections at pipeline operator field offices, compressor stations, and Midland-area facilities.
Upstream E&P Operators and Their Contractors
Pioneer Natural Resources, Diamondback Energy, Coterra Energy, and other Permian Basin E&P operators headquartered in Midland maintain Non-DOT company-policy testing programs for office and field employees and require contractor compliance programs as a condition of site access to their well locations. Drilling contractors, completion crews, and production service companies working for these operators require pre-access testing aligned with E&P operator safety requirements. We coordinate both DOT drug testing and Non-DOT workplace drug testing for E&P operators and their contractor workforces in the Midland area.
Aviation — Midland International Air and Space Port
Midland International Air and Space Port (MAF) serves as the primary aviation gateway for the Permian Basin oil and gas industry, with American Airlines, United Airlines, and Southwest Airlines service alongside significant charter and corporate aviation operations supporting energy company executives and field operations crews. FAA 14 CFR Part 120 applies to air carriers and ground service providers with safety-sensitive employees at MAF. We coordinate FAA-compliant aviation and airline employer collections at the airport and at corporate aviation facilities in the Midland area.
Contract Drilling and Well Service
Contract drilling companies operating rigs in the Permian Basin — including Patterson-UTI Energy, Helmerich & Payne, and Nabors Industries — maintain Non-DOT company-policy testing programs for rig crews mobilizing from Midland. Crews rotating to and from the field pass through Midland, making the city the logical collection point for pre-employment and random testing in a rotational workforce model. We coordinate collections at crew transport staging areas, mobilization offices, and lodging facilities in the Midland area.

Questions from employers in this region
ProPetro Holding deploys CDL oilfield service trucks from Midland to well sites across Midland, Ector, and Reeves Counties. How does pre-employment testing work when a driver is hired for an immediate deployment?
FMCSA 49 CFR Part 382 requires a verified negative pre-employment drug test result before a CDL driver performs their first safety-sensitive function. We coordinate same-day or next-morning collections at your Midland yard or hiring facility. Drivers are tested before they leave for the well site — not after arrival in a county where no clinic exists.
Kinder Morgan operates compressor stations and pipeline facilities across the Midland Basin. Can you reach a field office 40 miles east of Midland for a PHMSA random selection?
Yes. Pipeline operator field offices and compressor stations within the Midland Basin are within our Permian Basin service range. Logistics and travel are confirmed when you schedule the collection. You provide the facility address and donor count; we confirm what is workable.
Pioneer Natural Resources requires all contractors at its well locations to have a completed drug test within the past 30 days. Is that a DOT or Non-DOT requirement?
Pioneer's 30-day recency requirement is a Non-DOT company-policy access control standard — not a DOT-mandated testing frequency. It is separate from and in addition to any FMCSA 49 CFR Part 382 program the contractor operates for its CDL drivers. Program design and compliance obligations remain your responsibility under applicable law — we coordinate the collections.
Patterson-UTI has rig crews rotating through Midland between assignments. Can you test crews at a crew change facility or lodging location?
Yes. Crew rotation staging points — lodging facilities, mobilization offices, and crew transport hubs — are a standard mobile collection location for Permian Basin drilling contractors. We coordinate collections at the location you designate for the rotation handoff.
