UNSPSC 71121101: Acidizing through coiled tubing services

The pumping of acid into the wellbore through coiled tubing.

UNSPSC 71121101 Acidizing through coiled tubing services, a Commodity code, does not match the scope of work appearing in recent state and local procurement activity under this tag. The opportunities listed span well drilling, well plugging and abandonment, irrigation system installation, pump station maintenance, wastewater treatment infrastructure, and water treatment design — none of which involve acidizing or coiled-tubing interventions typical of oil and gas well stimulation. The code shows little relevant recent activity aligned with its nominal scope.

Recent solicitations tagged to this code originate from state environmental agencies (Michigan Department of Environment, Great Lakes, and Energy; Mississippi Oil and Gas Board), county governments (Sarasota, Gwinnett, Seminole, Hillsborough), municipalities (City of Albany, City of Bend, City of Reynolds, City of Wrens, City of Lubbock), special districts (Hilldale Water District, Boulder County Parks and Open Space), and state parks departments (Oregon Parks and Recreation, Texas Parks and Wildlife). Activity concentrates in Michigan, Mississippi, Georgia, Florida, Colorado, Oregon, Texas, and Illinois. Representative recent work includes the Michigan Department of Environment, Great Lakes, and Energy prequalification RFP for orphan well plugging and site restoration (RFP 7612600000025222, proposals due September 22, 2026); the City of Albany sealed-bid solicitation for Well No. 21 rehabilitation (Bid Ref. 27-032, due November 16, 2026); and the Mississippi Oil and Gas Board IFB for plugging, remediation, and reclamation of nine orphaned oil and gas wells in Jasper and Jones Counties (IFB RFx No. 3160008162, due December 18, 2026). The mismatch between the code name and actual procurement activity suggests either a consistent tagging error in the opportunities database or that this code has been repurposed or is dormant in state and local purchasing practice.
