UNSPSC 71121638: Well drilling pipe cleaning service

Cleaning service to remove rust, scale, cement and drilling fluids. This can be achieved via air rattling, outside and inside diameter brushing or by a hydro blasting system

UNSPSC 71121638 Well drilling pipe cleaning service is a Commodity code representing the specialized work of cleaning production tubing, casing, and associated piping systems inside wells during drilling, completion, remediation, and abandonment operations. State and local governments—primarily environmental and natural resources departments managing orphaned or remediated wells—procure this service as part of larger well plugging, abandonment, and site restoration projects. Recent opportunities show that pipe cleaning is solicited as one component within comprehensive well abandonment scopes of work rather than as a standalone service line.

The Michigan Department of Environment, Great Lakes, and Energy dominates recent activity, issuing four direct-solicitation contracts in July 2026 for orphaned gas storage well plugging across Gratiot and Montcalm counties (DS 260000000032 through DS 260000000035), all due July 21, 2026. These solicitations describe plugging, drilling, re-drilling, and site restoration at 38 total wells operated by New Haven Energy LLC, with comprehensive 68-line-item pricing matrices covering labor, equipment, materials, and specialized services including well casing, tubing rental, wireline services, drilling fluids, and cementing—of which pipe/tubing cleaning and flushing are embedded components. Contractors must have been prequalified through prior Michigan RFPs and attended mandatory pre-bid meetings; Davis-Bacon prevailing wage requirements apply; and awards are based on best value using technical scoring (key personnel, business-owned equipment, technical experience, vendor questions) rather than lowest price. Beyond Michigan, the code shows sparse recent state and local activity; a handful of well construction and rehabilitation solicitations from Florida counties (Marion, Collier, Sarasota), Texas, Mississippi, California, Wisconsin, Oregon, and Georgia include well development, disinfection, and testing but do not isolate pipe cleaning as a separately solicited line item. The code's narrow scope—cleaning of drilling and production tubulars—maps tightly to orphaned well remediation programs funded through federal Infrastructure Investment and Jobs Act initiatives, making state environmental and energy agencies the primary buyers.
