UNSPSC 71121124: Coiled tubing and stimulation service

Coiled tubing and stimulation service including N2unit is used for many well intervention operations and certain drilling applications. Coiled tubing (CT) refers to a continuous length of small-diameter steel pipe and related surface equipment as well as associated drilling, completion and workover, or remediation, technique. Well stimulation is a well intervention performed on an oil or gas well to increase production by improving the flow of hydrocarbons from the reservoir into the well bore.

UNSPSC 71121124, Coiled tubing and stimulation service, is a Commodity-tier code. State and local procurement activity under this code centers on orphan well plugging, abandonment, and site restoration services for gas storage wells and other oil and gas infrastructure, not on coiled tubing operations or pressure stimulation in the traditional sense. The Michigan Department of Environment, Great Lakes, and Energy dominates recent activity with multiple direct solicitations in July 2026 for plugging and site restoration at orphan gas storage wells in Gratiot and Montcalm counties. These efforts are part of a prequalification-restricted process requiring prior RFP awards; bidders must attend mandatory pre-proposal meetings and submit unit pricing for 68 line items covering rig services, labor classifications (roustabouts, toolpushers, cementer, electricians, welders), equipment rental, casing and tubing, wireline services, mud engineering, and waste disposal. Davis-Bacon prevailing wage requirements apply across all Michigan solicitations, with rates ranging from $39.57 to $41.32 per hour plus $25.25 to $40.00 in fringe benefits. Mississippi's Oil and Gas Board has issued companion solicitations for plugging and reclamation of orphaned oil and gas wells under federal IIJA funding, targeting multiple counties statewide. Texas state agencies (Railroad Commission, General Land Office) have opened well plugging and high-hydrogen-sulfide workover services to wider vendor pools, with HUB and ESDB set-asides in place. Illinois and Oregon round out the geographic spread with smaller-scale municipal well construction and rehabilitation efforts. Recent examples include Michigan's orphan well solicitations (DS7612600000000322, DS7612600000000332, DS7612600000000342, DS7612600000000352) due July 21, 2026, targeting three to fourteen wells per project and structured as direct solicitations with firm pricing and best-value award; Mississippi's orphaned well plugging bids (3160007967, 3160007966, 3160007881) due between April 13 and May 11, 2026, covering three to seven wells per solicitation; and the Texas General Land Office's high-H2S well pad services RFQ (455-26-1020) with responses due May 5, 2026. The code shows significant activity in the upper Midwest and South, with Michigan and Mississippi accounting for the plurality of recent high-value, multi-well contracts. Pursuit is justified for firms with orphan well plugging expertise, Davis-Bacon compliance capability, and established relationships with state environmental or energy agencies, particularly given the infrastructure funding available through federal IIJA programs.
