UNSPSC 71121101: Acidizing through coiled tubing services

The pumping of acid into the wellbore through coiled tubing.

UNSPSC 71121101 Acidizing through coiled tubing services is a Commodity code that encompasses well plugging, abandonment, and site restoration work, but the recent state and local opportunities show little activity aligned with the code's nominal scope. Instead, the 30 recent opportunities in the dataset span orphaned well plugging and remediation (Michigan and Mississippi), water well construction and rehabilitation (Florida, Texas, California, Oregon, Wisconsin, Georgia), wastewater pump station maintenance (Florida), and water treatment plant design and engineering (Texas)—none of which involve acidizing or coiled tubing intervention. The issuing bodies soliciting under the code are overwhelmingly state environmental or natural resources departments (Michigan Department of Environment, Great Lakes, and Energy; Mississippi Oil and Gas Board; Texas General Land Office; Illinois Department of Natural Resources), county utilities and public works departments (Seminole, Hillsborough, and Collier counties in Florida; San Bernardino County in California; Marion County in Florida), municipal water utilities (City of Lubbock, Eastern Municipal Water District, City of Pendleton, City of Palm Bay), and a handful of regional transit or special-purpose districts. Michigan's EGLE has posted the most recent activity—four overlapping direct solicitations in July 2026 for orphan well plugging across 38 total wells in Gratiot and Montcalm counties, all with July 21, 2026 response deadlines and mandatory prequalification through prior RFPs.

The code shows concentrated recent activity in the Great Lakes and Gulf Coast states—Michigan (Gratiot County orphan wells), Mississippi (seven statewide orphan wells, plus additional tranches), Florida (multiple county and municipal well, pump station, and water treatment contracts), Texas (water treatment design, railroad commission statewide plugging), California (Eastern Municipal Water District on-call well and pump services), and the broader Midwest and Southeast. No opportunities tagged to this code involve acidizing or coiled tubing services; the mismatch suggests the code is either misapplied by posting agencies or that state and local demand for acidic well treatment is negligible relative to mechanical plugging and well rehabilitation. A representative recent opportunity is the Michigan Department of Environment, Great Lakes, and Energy direct solicitation DS7612600000000322 for three orphan wells in Gratiot County (S.S. Smith 2, MCGC NH-333-A, MCGC NH-350A), posted July 16, 2026, with bids due July 21, 2026 under best-value criteria; another is the Mississippi Oil and Gas Board IFB for seven orphaned wells in five counties, posted March 6, 2026, with bids due April 13, 2026. Neither opportunity involves acidizing services or coiled tubing deployment.
