UNSPSC 71122105: Well consolidation services

The pumping of chemical systems that create a bond between sand grains to increase the unconfined compressive strength ucs of the rock matrix and therefore extend the life of the well by inhibiting sand production.

UNSPSC 71122105 Well consolidation services, a Commodity code, encompasses the plugging, abandonment, and site restoration of orphaned oil, gas, and water wells — work that state and local governments procure primarily through direct solicitation, competitive sealed bids, and RFPs focused on environmental remediation and infrastructure compliance. State and local buyers under this code include state departments of natural resources and environment, county governments, municipalities, and regional authorities managing abandoned well inventories funded by federal orphan well programs and state environmental budgets. Michigan's Department of Environment, Great Lakes, and Energy dominates recent activity, issuing four parallel direct solicitations in July 2026 for the plugging and site restoration of 38 orphan gas storage wells across Gratiot and Montcalm counties, each with response deadlines of July 21, 2026 and mandatory pre-proposal meetings on July 9, 2026; these solicitations require prequalification through prior RFP vehicles and specify Davis-Bacon prevailing wage compliance, unit-price bidding on 68-line-item pricing matrices, and best-value award criteria weighted on key personnel, business-owned equipment, technical experience, and vendor qualifications. Other recent activity spans Mississippi (seven and three orphaned oil and gas wells under Infrastructure Investment and Jobs Act funding in March–April 2026), Texas (high hydrogen sulfide well pad services and statewide plugging contracts across multiple Oil and Gas Division districts), Illinois (well installation at Union County State Fish and Wildlife Area in June 2026), and Florida (single-well abandonment services in Sarasota County in July 2026 capped at $50,000).

Geographic concentration in the code reflects significant recent federal infrastructure funding: Michigan dominates with four coordinated solicitations for gas storage well abandonment, Mississippi and Texas see orphaned well programs tied to Department of Interior grants under the Infrastructure Investment and Jobs Act, and Florida and Illinois handle smaller localized projects. Issuing bodies mix state natural resource departments, county environmental offices, and special-purpose districts. Representative work includes the Michigan Department of Environment, Great Lakes, and Energy's July 2026 direct solicitations (DS 260000000032 through 260000000035) for plugging three to fourteen orphan wells each with mandatory pre-proposal meetings and prequalification filters; the Mississippi Oil and Gas Board's April 2026 IFB for seven-well plugging across five counties (IFB RFx 3160007881) and three-well sets in Issaquena and Madison counties; and Sarasota County's July 2026 RFQ for single-well abandonment at 949 Ponder Avenue (quotes due July 10, 2026 with a $50,000 ceiling). Prequalification requirements, Davis-Bacon wage compliance, and federal funding conditions (Build America Buy America Act, prevailing wage, environmental liability insurance) are common filters across recent solicitations, creating barriers to entry for new entrants and favoring established contractors with prior state or federal well-abandonment experience.
