UNSPSC 71121900: Downhole fluid services

Includes services for oil, water and synthetic-base drilling fluids and additives.

UNSPSC 71121900 Downhole fluid services (Class) encompasses comprehensive well plugging and abandonment services, including site preparation, drilling fluids, cementing, wireline operations, and site restoration for orphaned oil, gas, and water wells managed by state environmental agencies and regional water authorities. State and local governments currently buy plugging and abandonment work through the Michigan Department of Environment, Great Lakes, and Energy (EGLE); the Texas General Land Office; the Mississippi Oil and Gas Board; the Railroad Commission of Texas; the Illinois Department of Natural Resources; and regional water districts in Florida, California, and Oregon. The issuing bodies span state environmental departments, state oil and gas regulators, county water utilities, municipal water systems, and special-purpose water districts; EGLE and the Mississippi Oil and Gas Board appear repeatedly as active purchasers of orphan well remediation services. Recent work solicited under the code emphasizes federal funding through the Infrastructure Investment and Jobs Act and related orphaned wells programs, with contractors typically prequalified through prior RFP processes and subject to Davis-Bacon prevailing wage requirements, Build America Buy America Act compliance, and firm-fixed unit pricing across 60–70 line items covering labor classifications, specialized equipment rental, fluids and materials, and site restoration.

The code shows sustained activity in Michigan's Gratiot and Montcalm counties, where EGLE posted four direct solicitations in July 2026 for orphan gas storage well plugging across 26 total wellheads operated by New Haven Energy LLC—including RFPs with July 21 response dates for three to fourteen wells per contract, each emphasizing 25-point technical scoring on personnel, equipment, experience, and worksheet responses with an 80-point minimum threshold and best-value award criteria. Additional recent work appears in Mississippi (plugging orphaned oil and gas wells across multiple counties under Infrastructure Investment and Jobs Act grants through April and May 2026), Texas (statewide well plugging through the Railroad Commission with HUB and disadvantaged veteran set-asides), and California and Florida (municipal water well maintenance and rehabilitation contracts). Geographic concentration is heaviest in Michigan, Mississippi, and Texas, with supplementary activity in the Upper Midwest and Southeast. Contractors pursuing this code should anticipate prequalification barriers, prevailing wage compliance, federal funding strings (Build America Buy America, Davis-Bacon, environmental certifications), and technical evaluation emphasis on key personnel and business-owned equipment availability rather than price.
