UNSPSC 71121900: Downhole fluid services

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

UNSPSC 71121900 Downhole fluid services is a Class code that spans water well drilling, well abandonment, orphan oil and gas well plugging, and associated subsurface remediation work solicited by state and local water utilities, environmental agencies, and park authorities. State and local governments buy under this code primarily to drill or rehabilitate production and monitoring wells for municipal water supply, to plug and abandon orphan or contaminated wells in compliance with environmental regulations, and to maintain existing well infrastructure including pump systems and casing repairs. Work ranges from straightforward municipal water well installation to complex orphan well abandonment under federal Infrastructure Investment and Jobs Act funding, with accompanying Davis-Bacon prevailing wage requirements on federally funded projects.

Recent solicitations show activity concentrated in water well construction and rehabilitation from municipalities and state environmental agencies, alongside orphan well plugging work from state oil-and-gas boards. The Michigan Department of Environment, Great Lakes, and Energy has posted multiple direct solicitations in July 2026 for prequalified contractor pools to plug orphan gas storage wells across Gratiot, Montcalm, and Kent Counties, with individual well packages ranging from three to 14 sites and federally funded prevailing wage compliance required. The Mississippi Oil and Gas Board issued two major competitive IFBs in July and October 2026 for orphan well plugging in Jasper, Jones, Adams, and Walthall Counties under Infrastructure Investment and Jobs Act Orphaned Wells Program funding. Municipal water utilities have posted RFPs and IFBs for new well construction: the City of Reynolds, Georgia (New Deep Well & Chemical Feed Building, August 2026, ITB); the City of Albany, Georgia (Well No. 21 Rehabilitation, November 2026, sealed bid); and Boulder County Parks and Open Space (Alexander Dawson and Mayhoffer stock water well installation, September 2026, RFP for $350,000). Illinois Department of Corrections has issued multiple RFQs for color video survey and well casing repair at Sheridan Correctional Center (multiple iterations August–September 2026). Hillsborough County and Seminole County, Florida, and San Bernardino County, California, have solicited on-call and master service agreements for ongoing well and pump maintenance across their utility systems (ITB and RFQ, May–August 2026, $688,073 estimated for Hillsborough two-year term). Geographic activity spans Michigan, Mississippi, Illinois, Georgia, Florida, Texas, California, Oregon, and Colorado, with particular concentration in Midwest and Southeast state environmental and water utility agencies managing federally funded well remediation initiatives.
