UNSPSC 71122304: Subsea well intervention or completion services

Services to convey mechanical tools or logging equipment to perform operational objectives downhole or to perform activities in the final stages of well construction to prepare a well for production.

UNSPSC 71122304 Subsea well intervention or completion services is a Commodity code that state and local governments interpret broadly as well plugging, abandonment, and site restoration for orphaned oil and gas wells, and well drilling, rehabilitation, and maintenance for municipal water systems. The code spans two distinct work streams: orphaned-well remediation funded through federal Infrastructure Investment and Jobs Act programs, and routine municipal water-well construction and rehabilitation. Michigan's Department of Environment, Great Lakes, and Energy has dominated recent activity, issuing four concurrent direct solicitations in July 2026 for plugging and site restoration at 38 orphaned gas storage wells across Gratiot and Montcalm counties (three wells in Section 3, fourteen in Section 4, nine in Sections 31-33, and twelve in Sections 5-10 and Plank), all due July 21, 2026, restricted to vendors prequalified through prior RFPs and requiring attendance at a mandatory July 9 pre-proposal meeting. Beyond Michigan, state and local issuing bodies—including Florida counties (Sarasota, Seminole, Marion, Hillsborough, Collier), California water districts (Eastern Municipal Water District), Mississippi's Oil and Gas Board, Texas agencies, Illinois Department of Natural Resources, and Oregon and Georgia municipalities—solicit well drilling, testing, rehabilitation, pump replacement, and monitoring-well construction under this code. Scope of work centers on mechanical and chemical well rehabilitation, plugging with cement, site restoration, equipment installation and testing, prevailing wage compliance, and environmental permitting.

Geographic spread is concentrated in Michigan for orphaned-well plugging, with secondary activity in Florida (Sarasota, Seminole, Marion, Brevard, Collier counties), California (Riverside), Mississippi (multi-county), Texas, Illinois, Oregon, and Georgia. Recent representative opportunities include the Michigan Department of Environment, Great Lakes, and Energy's four direct solicitations for New Haven Energy orphan-well plugging in Gratiot and Montcalm counties (RFP prequalification required, July 21, 2026 response), Seminole County's RFQ for wastewater pump station repair and refurbishment with a master service agreement structure (August 5, 2026 deadline), San Bernardino County Department of Public Works' RFQ for on-call well and pump maintenance services across 32 county water wells up to $2.8 million over five years (August 31, 2026 deadline), Hillsborough County's ITB for water well maintenance and repair at 67 irrigation and potable wells estimated at $688,073 over two years (June 12, 2026 response), and Mississippi Oil and Gas Board's IFB for orphaned well plugging and reclamation on seven wells (April 13, 2026, May 11, 2026, and April 28, 2026 deadlines across multiple procurements). Eligibility often requires prequalification through prior RFPs, attendance at mandatory pre-bid meetings, Davis-Bacon prevailing wage compliance, and comprehensive insurance; activity is steady but fragmented across jurisdictions and funding sources, with orphaned-well plugging driven by federal Infrastructure Investment and Jobs Act dollars and municipal work driven by aging water infrastructure.
