UNSPSC 71121621: Oil country tubular modification or testing services

Services for hard banding, recutting, rethreading or refurbishment or testing for pressure or leaks in OCTG.

UNSPSC 71121621 Oil country tubular modification or testing services, a Commodity code, encompasses well plugging, abandonment, and site restoration work that state and local governments procure when managing orphaned oil and gas wells and municipal water infrastructure. State and local environmental agencies, natural resource departments, and water utilities currently solicit under this code for comprehensive well services including drilling, casing installation, plugging with cement, wireline operations, and site reclamation. The Michigan Department of Environment, Great Lakes, and Energy has posted four direct solicitations in July 2026 for plugging and site restoration of 38 orphaned gas storage wells across Gratiot and Montcalm counties—three wells in Sec 3, 14 wells in Sec 4, 12 wells in Sections 5-10 and Plank, and nine wells in Sections 31-33—with proposals due July 21, 2026 (RFPs DS7612600000000322, DS7612600000000332, DS7612600000000342, DS7612600000000352). Bidders on these Michigan solicitations must be prequalified through prior RFPs and attend mandatory pre-proposal meetings; all work is subject to Davis-Bacon prevailing wage requirements, with scope including site supervision, equipment rental (pole rigs, derrick rigs, wireline), casing and tubing, cementing, mud engineering, waste disposal, and site restoration across 68 line items.

Michigan dominates recent activity under this code, with the state's orphaned well program driving four overlapping direct solicitations for gas storage well abandonment in the New Haven Energy fields. Mississippi and Texas also show activity—the Mississippi Oil and Gas Board has issued multiple invitation-for-bid solicitations for plugging and reclamation of seven to ten orphaned wells across multiple counties, with bids due in April 2026, while the Texas General Land Office and Railroad Commission of Texas have posted well plugging RFQs for high hydrogen sulfide wells and statewide plugging services. The geographic concentration reflects federal Infrastructure Investment and Jobs Act funding flowing through state orphaned wells programs. Illinois and Florida show isolated municipal well activity (Illinois Department of Natural Resources for irrigation well installation, Sarasota County for single-well abandonment) outside the mainstream abandonment pipeline. Evaluation across Michigan's recent solicitations emphasizes prequalification, technical experience (25%), business-owned equipment (25%), key personnel (25%), and vendor questionnaire response (25%), with 80-point minimum thresholds and best-value award criteria rather than lowest price. Pricing is firm for project duration with no changes permitted without state approval.
