UNSPSC 71122410: Underbalanced testing while drilling services

Testing borehole conditions while underbalance drilling.

UNSPSC 71122410 Underbalanced testing while drilling services is a Commodity code. State and local governments buying under this code procure well plugging, abandonment, and site restoration services for orphaned and non-producing oil, gas, and water wells—work that involves comprehensive drilling, casing installation, cement plugging, wireline operations, equipment removal, and environmental remediation to restore sites to usable condition. Recent solicitations show the code in active use for municipal water infrastructure projects such as well rehabilitation and new production well construction, though the specific "underbalanced testing while drilling" methodology does not appear prominently in the recent opportunities examined. Instead, state and local buyers are acquiring full-scope well abandonment and restoration, well rehabilitation for production use, and ancillary drilling and testing services under this taxonomy.

Recent activity is concentrated in Michigan (Michigan Department of Environment, Great Lakes, and Energy), which issued four direct solicitations in July 2026 for orphan gas storage well plugging and site restoration across Gratiot and Montcalm counties—a cluster of 38 wells collectively. All four Michigan solicitations (due July 21, 2026) are restricted to pre-qualified contractors and carry Davis-Bacon prevailing wage requirements. County and municipal buyers in Florida, Texas, Illinois, Mississippi, California, and Oregon are also active, posting RFPs and ITBs for water well construction, rehabilitation, and maintenance services at individual production or monitoring wells. The code shows geographic spread across the upper Midwest, Southeast, Southwest, and Pacific Northwest, with no single jurisdiction dominating. Representative recent opportunities include the Michigan Department of Environment, Great Lakes, and Energy direct solicitation DS7612600000000322 (Orphan Well New Haven Sec 3, three wells in Gratiot County, due July 21, 2026), Seminole County Board of County Commissioners Invitation for Bid CC710026HSMA (Wastewater Pump Station R & R, due August 5, 2026), and the Mississippi Oil and Gas Board Invitation for Bids 3160007967 (plugging and reclamation for seven orphaned oil and gas wells, due May 11, 2026). This code remains active and competitive for firms with drilling, plugging, equipment mobilization, and environmental remediation capability.
