UNSPSC 71121509: Geologically steered wells

The use of geological information to guide a well to its target, especially when the geology turns out to be different from that expected.

UNSPSC 71121509 Geologically steered wells, a Commodity code, encompasses drilling services for orphan oil and gas well abandonment and environmental remediation projects that state and local governments purchase through environmental departments and natural resources boards. Recent state and local solicitations show this code is being applied—sometimes loosely—to well abandonment and plugging work across multiple jurisdictions. The Michigan Department of Environment, Great Lakes, and Energy has posted four direct solicitations in July 2026 (DS 260000000032, DS 260000000033, DS 260000000034, and DS 260000000035) for plugging and site restoration of 38 orphan gas storage wells in Gratiot and Montcalm counties, with proposals due July 21, 2026. These solicitations require prequalification through prior RFPs, mandatory pre-bid attendance on July 9, 2026, Davis-Bacon prevailing wage compliance, unit pricing across 68 line items covering labor, equipment, materials, and specialized services, and technical evaluation weighted equally on key personnel, business-owned equipment, company experience, and vendor questions (minimum 80 points for award consideration). The scope includes site supervision, rig operations, well casing and tubing rental, cementing, wireline services, waste disposal, and site restoration on wells operated by New Haven Energy LLC with gas storage wellheads and orbit valves.

Activity under the code is concentrated in Michigan, Mississippi, Texas, and Florida, with orphan well remediation dominating state-level procurement. The Mississippi Oil and Gas Board has issued multiple IFBs for well plugging and reclamation across seven wells (IFB 3160007967, posted March 24, 2026, due April 28, 2026) and seven additional wells (IFB 3160007881, posted March 6, 2026, due April 13, 2026), both funded through Infrastructure Investment and Jobs Act Formula grants and requiring five years' documented experience, Mississippi business licensure, and compliance with Build America Buy America Act provisions. The Texas General Land Office posted RFQ 455-26-1020 in May 2026 for high hydrogen sulfide well services and statewide well plugging work (RFQ 455-26-1006, posted February 25, 2026), with emphasis on HUB and disadvantaged vendor participation. Beyond oil and gas remediation, recent opportunities show the code tag being applied inconsistently to municipal water well construction and repair—the City of Palm Bay's production well solicitation (30RFP26, due April 28, 2026) and Marion County's potable well construction (26B-081, due May 21, 2026) fall outside the nominal geologically steered wells scope but signal that state procurement systems are classifying diverse well work under this commodity code. Orphan well plugging dominates current activity; municipal potable and irrigation well work represents a secondary but growing segment, though it does not align with the code's oil and gas remediation title.
