UNSPSC 71121115: Milling through coiled tubing services

The use of a mill or similar downhole tool to cut and remove material from equipment or tools located in the wellbore through coiled tubing..

UNSPSC 71121115 Milling through coiled tubing services (Commodity) does not align with the state and local procurement activity currently tagged under this code. Recent opportunities posted under this classification span water well drilling, rehabilitation, abandonment, and plugging services; orphan oil and gas well remediation; wastewater pump station maintenance and repair; irrigation system installation; and utility infrastructure improvements—none of which involve coiled tubing milling operations. The code appears to be applied as a catch-all or default classification for subsurface drilling and well-service work despite the nominal scope referencing specialized pressure-control drilling techniques. Activity is concentrated among state environmental and energy agencies managing orphaned well programs, county and municipal utilities departments, park and recreation authorities, and water service districts across Florida, Michigan, Mississippi, Georgia, Texas, Illinois, and Colorado.

The issuing bodies are predominantly state environmental departments (Michigan EGLE, Mississippi Oil and Gas Board, Illinois Department of Corrections and Natural Resources), county utilities and water authorities (Hillsborough County, Seminole County, Gwinnett County, Sarasota County, Escambia County, Boulder County, San Bernardino County), city water departments and parks agencies (Lubbock, Austin, DeBary, Albany, Reynolds, Wrens, Bend, Ocala, Pascagoula), and special-purpose districts (Hilldale Water District). Michigan leads in recent activity with multiple direct solicitations for orphan well plugging under federally funded Infrastructure Investment and Jobs Act programs; the state has posted over a dozen well-remediation solicitations since June 2026. Recent representative opportunities include the Mississippi Oil and Gas Board's IFB for plugging nine orphaned oil and gas wells across Jasper and Jones Counties with bids due December 18, 2026; Seminole County's IFB for wastewater pump station maintenance and repair with bids due June 17, 2026; Hillsborough County's ITB for water well maintenance and repair services supporting 67 wells across multiple parks with an estimated contract value of $688,073.00 and bids due June 12, 2026; and the Michigan EGLE's direct solicitations for orphan well plugging at multiple sites in Gratiot County with proposals due July 21, 2026, restricted to prequalified vendors and subject to Davis-Bacon prevailing wage requirements. The code shows no recent activity and little relevance; pursu pursuit depends on whether your firm performs subsurface drilling, well rehabilitation, or site restoration rather than coiled tubing pressure-control operations.
