UNSPSC 71122300: Subsea well services

Services for installation, testing and operations of wells located on the seabed.

UNSPSC 71122300 Subsea well services is a Class code that state and local governments are using to procure terrestrial well drilling, plugging, abandonment, and rehabilitation services—not subsea work. The recent solicitation stream shows municipalities, counties, state environmental agencies, and special-purpose districts issuing RFPs, RFQs, IFBs, and ITBs for water well construction and replacement, irrigation well installation, orphan oil and gas well plugging, pump station rehabilitation, well abandonment, monitoring well installation, and associated water infrastructure. The code's nominal name does not match the work actually being solicited; state and local buyers are tagging well-drilling and plugging projects under this code despite its subsea classification.

Recent activity clusters in Michigan (orphan well plugging through the Department of Environment, Great Lakes, and Energy), Mississippi (orphan oil and gas well remediation), Florida (irrigation improvements, monitoring wells, well abandonment, pump station maintenance), Georgia (municipal well construction and rehabilitation), Illinois (correctional facility well repair), and Texas (state parks utility improvements). Representative solicitations include the Michigan Department of Environment, Great Lakes, and Energy's prequalification RFP for orphan well plugging services (RFP 7612600000025222, proposals due September 22, 2026), which awarded five contractors totaling $800,000 for one year and five months; the Mississippi Oil and Gas Board's IFB for plugging and remediation of nine orphaned wells in Jasper and Jones Counties (IFB 3160008162, bids due December 18, 2026, mandatory pre-bid October 22, 2026); Hillsborough County's two-year ITB for water well maintenance and repair services across 67 wells ($688,073 estimated value, bids due June 12, 2026); and the City of Albany's sealed bid for Well No. 21 rehabilitation (sealed bids due November 16, 2026). Infrastructure Investment and Jobs Act federal funding and Build America, Buy America Act compliance requirements are common across recent orphan well and water infrastructure solicitations. Davis-Bacon prevailing wage standards apply to federally funded projects. Contractors frequently must demonstrate prior well-drilling or well-plugging experience, hold state water well contractor licenses, carry pollution liability and environmental insurance, and comply with state-specific cement plugging and abandonment standards.
