UNSPSC 71121303: Downhole drilling reaming and gauge protection services

Services to increase the size of the wellbore part of directional or performance drilling services.

UNSPSC 71121303 Downhole drilling reaming and gauge protection services is a Commodity code that encompasses well plugging, abandonment, and site restoration services for orphaned oil and gas wells, as well as comprehensive municipal water well construction, rehabilitation, and maintenance work. State and local governments procure under this code primarily for plugging and remediating abandoned fossil fuel wells under federal Orphaned Wells Program grants, and for constructing, rehabilitating, and maintaining public water supply and monitoring wells to support municipal water systems and irrigation infrastructure.

The issuing bodies span state departments of environment and energy, state oil and gas boards, county governments, cities, water districts, and municipalities. The Michigan Department of Environment, Great Lakes, and Energy has dominated recent activity with four concurrent direct solicitations (posted July 16–29, 2026) for plugging 38 total orphaned gas storage wells in Gratiot and Montcalm Counties, each requiring prequalification through prior RFPs and mandatory pre-bid attendance. Orphaned well work is concentrated in Michigan, Mississippi, and Texas—the Mississippi Oil and Gas Board has issued multiple IFBs for well plugging across the state, and the Texas General Land Office and Railroad Commission of Texas have ongoing programs. Water-supply and municipal well work appears across Florida (Sarasota, Seminole, Hillsborough, Marion, Collier, and Brevard counties), California (Eastern Municipal Water District, Riverside County), Texas (City of Lubbock, City of Palm Bay), Oregon (City of Bend, City of Pendleton), Wisconsin (City of Watertown), Georgia (City of Helen, McIntosh County), and Illinois (Department of Natural Resources). Recent representative solicitations include the Michigan Department of Environment, Great Lakes, and Energy direct solicitation DS7612600000000322 (three orphan wells, proposals due July 21, 2026, IFB format with 68-line unit-pricing matrix, Davis-Bacon wages, best-value award), Seminole County Board of County Commissioners CC-7100-26 (wastewater pump station maintenance and repair master service agreement, proposals due August 5, 2026, RFQ format, M/WBE encouraged), Eastern Municipal Water District RFP #3931 (on-call well maintenance and rehabilitation services, proposals due April 23, 2026, minimum two awards, five-year term), and Hillsborough County ITB 26-00234 (water well maintenance and repair for 67 irrigation and potable wells across county parks, $688,073 estimated value, due June 12, 2026). Orphaned well and gas storage work carries Davis-Bacon prevailing wage requirements and federal Orphaned Wells Program funding; municipal water work often requires California prevailing wages, Florida licensing by water management district, and state-specific well construction certifications.
