UNSPSC 71122300: Subsea well services

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

UNSPSC 71122300 Subsea well services, a Class code, encompasses drilling, plugging, and site restoration of orphan and abandoned wells, including gas storage wellheads, potable water supply wells, and monitoring wells. State and local governments procure this work through departments of environmental quality, county utilities departments, water authorities, cities, and municipalities, with the Michigan Department of Environment, Great Lakes, and Energy, Florida counties, Texas state agencies, and the Mississippi Oil and Gas Board appearing as repeat buyers in recent months.

Recent solicitations show concentrated activity in Michigan, where the Michigan Department of Environment, Great Lakes, and Energy issued four direct solicitations in July 2026 (due July 21, 2026) for plugging and site restoration across 38 orphan gas storage wells in Gratiot and Montcalm Counties operated by New Haven Energy LLC—each solicitation restricting bidding to prequalified contractors and requiring Davis-Bacon prevailing wage compliance, detailed unit pricing across 68 line items, and best-value evaluation weighting technical qualifications at 100 points minimum. Parallel activity spans Florida (Sarasota County requesting well abandonment under RFQ 2026QQ759 with a $50,000 ceiling, due July 10, 2026; Seminole County requesting on-call pump station repair and refurbishment services under ITB CC710026HSMA, due August 5, 2026), Illinois (Illinois Department of Natural Resources requesting well and pump installation for Union County State Fish and Wildlife Area under IFB 26-422DNR-LNDMG-B-52982, small-business set-aside, due July 9, 2026), and California (San Bernardino County requesting on-call well and pump maintenance and repair services for water districts with a $2.8 million five-year ceiling, proposals due August 31, 2026). Geographic spread concentrates in the Great Lakes region, Florida, and the Southwest, with recent work orders and master service agreements favoring contractors holding relevant state well-drilling licenses, five years of documented experience in water well or orphan well services, prevailing wage compliance certification, and comprehensive liability and pollution insurance. The code shows active procurement volume with response deadlines ranging from immediate to mid-August 2026 and a mix of small discrete projects ($50,000 and under) and larger multi-well programs ($2.8 million over contract terms).
