UNSPSC 71122101: Acid sand control pumping services

Typically before a sand control treatment, the formation near the wellbore is acidized to remove any damage caused during drilling or preparatory work on the well.

UNSPSC 71122101 Acid sand control pumping services is a Commodity code describing well abandonment, plugging, and site restoration work that state and local governments purchase as part of orphan-well remediation and infrastructure replacement programs. The code sees activity primarily from state departments of energy and environment managing oil and gas legacy sites, county utilities departments operating municipal water systems, and special-purpose water districts. State and local buyers solicit comprehensive well services including plugging operations, site preparation, equipment removal, restoration, and associated drilling and cementing work, often bundled with infrastructure replacement for potable-water or wastewater systems. The Michigan Department of Environment, Great Lakes, and Energy has dominated recent activity, issuing four direct solicitations in July 2026 for plugging and site restoration of orphan gas storage wells in Gratiot and Montcalm counties—covering 38 wells across four separate RFP-equivalent notices (DS 260000000032 through 260000000035) due July 21, 2026—all requiring prequalification through prior RFP processes and mandatory pre-proposal meetings. These Michigan notices specify Davis-Bacon prevailing wage requirements, unit-price scheduling across 68 line items, and best-value selection based on key personnel (25%), business-owned equipment (25%), technical experience (25%), and vendor-response worksheets (25%), with minimum 80-point technical thresholds.

Beyond Michigan's concentrated orphan-well work, the code shows secondary activity in Florida water utilities—Seminole County seeking wastewater pump station maintenance and repair services (RFQ due August 5, 2026; three-year initial term with optional renewals), Sarasota County requesting well abandonment quotes for residential property (RFQ due July 10, 2026; $50,000 ceiling), and Hillsborough County issuing an ITB for water-well maintenance and repair across 67 irrigation and potable wells ($688,073 estimated value; two-year term). Illinois Department of Natural Resources and Mississippi Oil and Gas Board also posted orphan-well plugging solicitations in the past six months. Geographic spread concentrates in the Upper Midwest and Southeast, with Michigan accounting for the largest pipeline of near-term work and Florida showing consistent municipal well-maintenance demand. The code shows strong current activity, particularly in federally funded orphan-well programs under the Infrastructure Investment and Jobs Act, though the primary recent opportunities are prequalification-limited (Michigan restricts bidding to prior RFP awardees), narrowing the pool for new entrants pursuing plugging-services work.
