UNSPSC 71121636: Wellhead equipment services

Services for installation or maintenance of wellhead equipment.

UNSPSC 71121636 Wellhead equipment services is a Commodity code covering plugging, abandonment, remediation, and site restoration services for orphaned oil and gas wells, as well as on-call maintenance and rehabilitation work on production water wells serving municipal and utility systems. State and local governments procuring under this code are primarily state environmental or energy agencies (Michigan Department of Environment, Great Lakes, and Energy; Texas General Land Office; Mississippi Oil and Gas Board; Illinois Department of Natural Resources), county governments managing water utilities (Hillsborough County, Marion County, Collier County, Seminole County in Florida; San Bernardino County in California), and municipal water departments (City of Bend, City of Lubbock, City of Santa Cruz, Eastern Municipal Water District). The Michigan Department of Environment, Great Lakes, and Energy has issued multiple recent solicitations for orphan well plugging in Gratiot and Montcalm counties, while Florida counties are actively procuring water well maintenance, construction, and rehabilitation services. The work being solicited spans two distinct categories: federal-grant-funded orphaned well plugging programs (addressing decommissioned oil and gas wells) and municipality-driven production well construction, maintenance, and rehabilitation for potable and irrigation water supply. Representative recent solicitations include four Michigan direct solicitations issued July 16, 2026, by the Michigan Department of Environment, Great Lakes, and Energy for plugging three to fourteen orphan gas storage wells in Gratiot County with responses due July 21, 2026 under a prequalified bidder model; Hillsborough County's June 2026 ITB 26-00234 for water well maintenance and repair services at 67 wells across county parks, estimated at $688,073.00 for two years; and Marion County, Florida's May 2026 IFB for construction of four potable water wells at treatment plants. The geographic spread is concentrated in the upper Midwest and coastal Southeast, with the highest recent activity in Michigan (orphan gas well plugging), Florida (water well maintenance and treatment plant construction), and states with active Oil and Gas Board programs (Texas, Mississippi). California, Oregon, Georgia, and Wisconsin show periodic activity in water well rehabilitation and production well construction.

The code sees substantial activity from state environmental agencies administering federal Orphaned Wells Program funding through the Infrastructure Investment and Jobs Act, county and municipal water utilities managing aging well infrastructure, and regional water districts operating multi-facility systems. Opportunities currently posted range from $688,073.00 (Hillsborough County two-year maintenance contract) to estimated project budgets exceeding $2.9 million (Collier County production well improvements). Bidders must maintain professional well drilling and construction licenses in the relevant state, demonstrate five or more years of documented experience with reference verification, carry comprehensive insurance including general liability of $1 million to $2 million and workers' compensation coverage, and comply with prevailing wage requirements where federal funding is involved. Davis-Bacon Act compliance is standard on federally funded orphan well plugging; California Labor Code Section 1720 prevailing wage applies to EMWD and San Bernardino County work. Many solicitations require prequalification through prior RFPs before bidding on task orders, and several award to multiple pre-qualified contractors on an on-call, as-needed basis with no guaranteed work volume. Best-value evaluation dominates award decisions rather than lowest price, with technical factors (key personnel, equipment lists, experience, capability) typically weighted 75–80 percent and price 20–25 percent.
