UNSPSC 71121610 Well drilling engineering services (Commodity) encompasses the full scope of well abandonment, plugging, remediation, and site restoration work that state and local governments procure for managing orphaned oil and gas wells, water supply infrastructure, and remediation projects. The code captures comprehensive engineering and construction services including well plugging operations, site remediation, equipment removal, aquifer storage and recovery (ASR) conversions, geotechnical evaluation, permitting support, and construction administration—not abstract engineering consultation alone. State and local buyers soliciting under this code include state departments of environment and energy, state oil and gas boards, county utilities departments, municipal water utilities, environmental service authorities, and regional water management districts. The Michigan Department of Environment, Great Lakes, and Energy has dominated recent activity with four concurrent direct-solicitation contracts for orphan well plugging across Gratiot and Montcalm Counties (July 2026 response date), requiring prequalified contractors to plug 38 gas storage wells operated by New Haven Energy LLC under Davis-Bacon prevailing wage requirements and best-value evaluation. Similar orphan-well plugging solicitations have been issued by the Mississippi Oil and Gas Board (three bids posted March–April 2026), the Illinois Department of Natural Resources (March 2026), and the Texas General Land Office (May 2026).

Geographic concentration reflects recent federal funding through the Infrastructure Investment and Jobs Act Orphaned Wells Program, with major activity in Michigan, Mississippi, Illinois, Texas, and Florida. Outside the orphan-well category, municipal water utilities across Florida, California, Arizona, Oregon, and Wisconsin are soliciting well improvement, maintenance, rehabilitation, and new-construction services—including Hillsborough County (two-year maintenance contract, $688,073.00, June 2026 response), Sarasota County (exploratory and monitor well construction, July 2026), Marion County (four potable wells, May 2026), Eastern Municipal Water District in California (on-call well and pump services, $2.8 million, five-year term, August 2026 response), and San Bernardino County (on-call well and pump services, August 2026 response). Representative recent opportunities include the Michigan Department of Environment, Great Lakes, and Energy soliciting plugging and site restoration for 38 orphan gas storage wells across four separate direct solicitations (DS 260000000032, 260000000033, 260000000034, 260000000035) with July 21, 2026 proposal deadlines requiring prequalification through prior RFPs and attendance at mandatory July 9, 2026 pre-proposal meetings; the Hillsborough County Board of County Commissioners issuing an ITB for water well maintenance and repair services covering 67 irrigation and potable wells at $688,073.00 for two years (ITB 26-00234, June 12, 2026 response); and San Bernardino County Department of Public Works procuring on-call well and pump maintenance and repair services for 32 water wells and 28 booster pump locations across multiple districts at up to $2.8 million over five years (RFQ SPD126SPDAD6431, August 31, 2026 response). Most recent opportunities carry mandatory prevailing wage and Davis-Bacon requirements, require three to five years of documented well construction or maintenance experience, and emphasize best-value evaluation over lowest price.
