UNSPSC 71122301: Subsea well diving services

Diving services including air, hardsuits, intervention, mixed gas, saturation, surface.

UNSPSC 71122301 Subsea well diving services, a Commodity code, covers plugging, abandonment, and remediation of orphaned oil and gas wells and municipal water infrastructure through subsurface drilling and intervention services. State and local procurement activity under this code is dominated by orphan-well remediation solicitations from state energy departments and boards, supplemented by municipal water utilities procuring well drilling, rehabilitation, and replacement work. The Michigan Department of Environment, Great Lakes, and Energy has issued the most concentrated recent activity, posting four direct solicitations in July 2026 for plugging and site restoration across 38 orphaned gas storage wells in Gratiot and Montcalm counties—all with July 21 response deadlines and all requiring prior prequalification through an earlier round of RFPs. The Mississippi Oil and Gas Board likewise solicited orphan-well plugging services across multiple counties through competitive Invitations for Bid in March and April 2026. Beyond orphan-well work, water utilities in Florida, California, Oregon, Texas, and Georgia have posted bids and RFPs for municipal well drilling, rehabilitation, and testing services, including the Eastern Municipal Water District in California (RFP 3931 for well maintenance and rehabilitation, responses due April 23, 2026), the City of Palm Bay, Florida (NRO-3 through NRO-6 production wells, bids due April 28, 2026), and the Illinois Department of Natural Resources (Union County well and pump installation under a small-business set-aside, bids due July 9, 2026).

The issuing-body mix spans state agencies managing orphaned wells, county and municipal utilities departments, and special districts. Orphan-well procurement is concentrated at the state level—Michigan EGLE, Mississippi Oil and Gas Board, Texas General Land Office, and the Railroad Commission of Texas—often tied to federal funding through the Infrastructure Investment and Jobs Act. Water utilities are fragmented across counties and cities: Seminole County, Hillsborough County, and Sarasota County in Florida; San Bernardino County in California; Volusia County and Marion County in Florida; and cities including Lubbock, Bend, Palm Bay, Pendleton, and Watertown. Geographic concentration is heaviest in the Gulf Coast and Great Lakes regions—Michigan, Mississippi, Texas, and Louisiana—where orphan-well programs drive volume, along with dispersed municipal water-infrastructure activity across Florida, California, Oregon, and the upper Midwest. Recent representative opportunities include the Michigan Department of Environment, Great Lakes, and Energy soliciting plugging and site restoration for three orphaned wells in Gratiot County (DS7612600000000322, direct solicitation, due July 21, 2026); Hillsborough County, Florida, issuing an ITB for water well maintenance and repair services at 67 irrigation and potable wells across multiple parks, estimated at $688,073 over two years (ITB 26-00234, bids due June 12, 2026); and the Eastern Municipal Water District in California requesting RFP proposals for on-call well maintenance and repair services across 32 wells and 28 booster pump locations with a five-year maximum of $2.8 million (SPD126SPDAD6431, proposals due August 31, 2026).
