DOT-COMPLIANT · ON-SITE EMPLOYER DRUG TESTING
Mobile Employer Drug Testing in Odessa, Texas
We travel to your oil field service yard, pipe yard, fleet terminal, or job site and administer federally compliant DOT and Non-DOT collections on-site. No clinic. No missed crew rotations.
Odessa is the Permian Basin's primary oil field service and equipment hub, operating as the operational counterpart to Midland's corporate concentration. While Midland hosts the E&P operators' executive offices, Odessa is where the truck yards, pipe yards, equipment rental depots, and oil field service company terminals are concentrated. Halliburton, SLB (Schlumberger), Baker Hughes, and Weatherford all maintain major Permian Basin service operations in the Odessa area. Mid-Continent Supply Company, Frank's International, and dozens of regional FMCSA-regulated oil field service carriers operate from Odessa yards. PHMSA-regulated pipeline and midstream operators with Permian Basin gathering systems — including Targa Resources and MPLX — have field operations that stage through Odessa. For an oil field service company hiring CDL drivers for immediate well-site deployment, mobile pre-employment testing at the Odessa yard is the only model that does not lose a hire to a same-day clinic wait.
OnSite Employer Testing coordinates mobile drug testing collections at your Odessa service yard, equipment terminal, or pipeline field office. We do not operate a clinic. Review how it works or browse all locations we serve.
Why Odessa Employers Need Mobile Testing
Odessa's oil field service economy runs on same-day deployment. A CDL driver hired at an Odessa oil field service yard on a Tuesday morning is expected to reach a Permian Basin well pad by Tuesday evening. A pre-employment test that requires a clinic visit — with a wait, a drive, and a wait for results — takes that driver out of the hiring pipeline for four to six hours in a market where the well operator has a rig standing by. Mobile collection at the service yard, completed before the driver's first safety-sensitive function, is the operationally mandatory model for Permian Basin oil field service.
Pipe yards and equipment rental depots in Odessa operate CDL-heavy outbound delivery fleets that require ongoing FMCSA random programs. A random selection for a pipe truck driver that pulls him off the dispatch board costs a delivery appointment. Mobile collection at the yard, scheduled by the DER at an appropriate operational moment, keeps the random program running without disrupting daily freight commitments.
Program design and compliance obligations remain your responsibility under applicable law — we coordinate the collections.
Industries We Serve in Odessa
Oil Field Service Companies
Halliburton, SLB, Baker Hughes, and Weatherford operate Permian Basin service facilities in Odessa, employing CDL drivers for fluid transport, pressure pumping equipment moves, and well site logistics. These and dozens of smaller Odessa-based oil field service contractors maintain FMCSA 49 CFR Part 382 programs for their CDL-driving workforce alongside Non-DOT company-policy programs for their non-CDL field employees. We coordinate both DOT drug testing and Non-DOT workplace drug testing at service company yards and facilities throughout Ector County.
Pipe Yards and Equipment Supply
Mid-Continent Supply Company and other pipe, valve, and fitting suppliers operating from Odessa run CDL outbound delivery fleets serving Permian Basin well sites and pipeline construction projects throughout West Texas. FMCSA-regulated deliveries of tubular goods, fittings, and wellhead equipment require pre-employment and random testing programs for CDL drivers. We coordinate logistics and transportation collections at pipe yard dispatch areas and equipment depot facilities in Odessa.
Pipeline and Midstream Field Operations
Targa Resources, MPLX, and other midstream operators with Permian Basin gathering and processing infrastructure maintain field operations staging through the Odessa area. PHMSA 49 CFR Part 199 pipeline employee requirements apply to field technicians and compressor station operators in the Ector County region. We coordinate PHMSA-compliant energy and utilities collections at midstream field offices and compressor station facilities in and around Odessa.
Drilling Contractors and Completion Crews
Contract drilling companies and completion service operators rotating crews through Odessa between Permian Basin rig assignments use the city as a crew change hub. Non-DOT pre-employment testing for new rig employees and random testing for active crew members are coordinated at the crew change facility or mobilization office. We coordinate collections at the location where crews are physically present — the lodging facility, mobilization hub, or company office — not at a clinic across Odessa.
Construction and Infrastructure
Active pipeline construction, plant construction, and infrastructure projects in the Permian Basin generate construction contractor testing demand throughout the Odessa area. CDL crane operators, heavy equipment operators, and CDL truck drivers on pipeline construction projects require FMCSA DOT programs. General contractor Non-DOT programs cover non-CDL craft workers. We coordinate both program types at job site trailers and contractor staging yards in and around Ector County.

Questions from employers in this region
Halliburton's Odessa facility hires CDL pressure pumping drivers on short notice for immediate Permian Basin deployments. Can you complete a pre-employment collection at the yard the same morning the driver is hired?
Yes. Same-day pre-employment collections at oil field service yards are a core use case for mobile testing. We coordinate collections at your facility on the schedule your hiring team needs — not on a clinic's walk-in availability. Contact us at (219) 315-0345 to establish a standing collection arrangement for your Odessa yard.
SLB has both CDL and non-CDL field employees in Odessa. Do both groups need the same drug test?
No. CDL drivers operating commercial motor vehicles in interstate commerce require an FMCSA 49 CFR Part 382 DOT drug test — a 5-panel urine specimen collected on a federal CCF form and analyzed at a SAMHSA-certified laboratory. Non-CDL field employees are tested under a Non-DOT company-policy program, which can use different panels, forms, and cutoffs as defined by your policy. Program design and compliance obligations remain your responsibility — we coordinate the collections for both program types.
A pipe truck driver had an accident on a Permian Basin county road. The road is not a public U.S. highway. Does FMCSA post-accident testing still apply?
FMCSA post-accident testing is triggered by accidents involving a commercial motor vehicle on a public road — including county roads that are publicly maintained. A county road in West Texas is generally a public road. If the accident meets FMCSA's post-accident testing thresholds (fatality, injury requiring medical treatment away from the scene, or disabling damage to a vehicle requiring a tow), post-accident testing is required. Program design and compliance obligations remain your responsibility — we coordinate the collections.
Do you serve Odessa employers on weekends and outside normal business hours?
Yes. Oil field service operations run seven days a week in the Permian Basin. We coordinate collections at your facility on a schedule that fits your operational calendar. Contact us at (219) 315-0345 or use our instant quote calculator to discuss scheduling.
