UNSPSC 71122310: Subsea well project management and engineering service

Service for oil and gas exploration, development, and production facilities. Service can include from initial evaluation of producing formations to drilling, completion, stimulation, and well maintenance for a single well

UNSPSC 71122310 Subsea well project management and engineering service is a Commodity code. State and local governments do not buy subsea well work under this code—the recent opportunities block contains no solicitations for offshore or deepwater engineering services. Instead, the code appears to be a taxonomy mismatch. The opportunities tagged to 71122310 span orphan onshore well plugging, wastewater pump station rehabilitation, potable water well construction, irrigation well installation, and monitoring well replacement—all terrestrial, inland water-supply and environmental remediation activities with no subsea component. Soliciting bodies include the Michigan Department of Environment, Great Lakes, and Energy; county water utilities and treatment authorities across Florida, California, Mississippi, Texas, and the Midwest; municipal water departments in Oregon and Georgia; and special-purpose districts such as Seminole County Utilities and the Eastern Municipal Water District. The work actually being procured under this code is plugging and abandonment of orphaned oil and gas wells; construction and rehabilitation of municipal production, irrigation, and potable supply wells; wastewater pump station maintenance and renewal; and specialized engineering design for well infrastructure improvements—all managed through direct solicitations, RFPs, and IFBs with mandatory prequalification, prevailing wage compliance, and Davis-Bacon Act requirements where federal funding applies.

Recent activity is concentrated in Michigan (four orphan-well plugging solicitations from EGLE for New Haven Energy wells in Gratiot County due July 21, 2026), Florida (Seminole County wastewater pump station R & R, Sarasota County well abandonment and exploratory wells, Collier County and Marion County production well construction), California (Eastern Municipal Water District well maintenance and digester gas utilization), and Mississippi and Texas (multiple state-level orphan well plugging contracts). The Michigan opportunities represent the largest single cluster: the Department of Environment, Great Lakes, and Energy issued four direct solicitations in July 2026 for plugging and site restoration of 26 orphan gas storage wells across multiple sections in Gratiot and Montcalm Counties, each with proposals due July 21, 2026, requiring prequalification through prior RFPs and mandatory pre-proposal meetings. Geographically, the code shows heaviest recent activity in the Great Lakes region and the Gulf Coast states, with scattered activity in the Interior West and Pacific Northwest. The code's nominal name does not describe the work being solicited; contractors evaluating this taxonomy entry should verify scope against actual opportunity postings before investing in qualification or proposal effort.
