UNSPSC 71121113: Horizontal isolation oilfield services

Performing of horizontal isolation services through coiled tubing.

UNSPSC 71121113 Horizontal isolation oilfield services (Commodity) encompasses plugging, abandonment, and site restoration of orphaned oil and gas wells—work that state and local governments procure primarily through environmental remediation and natural resource management agencies. State and local buyers under this code are almost entirely state departments tasked with environmental compliance and orphan well remediation, along with occasional county and municipal utilities managing groundwater infrastructure; the Michigan Department of Environment, Great Lakes, and Energy and Mississippi Oil and Gas Board are the most active repeat buyers in recent solicitations. Recent opportunities reflect two distinct service streams: (1) comprehensive orphan well abandonment involving plugging, drilling, re-drilling, site restoration, and equipment removal under Davis-Bacon prevailing wage requirements, and (2) specialized horizontal isolation, casing installation, and well integrity work performed by prequalified contractors on multi-well projects. The Michigan Department of Environment, Great Lakes, and Energy issued four direct solicitations in July 2026 (DS7612600000000322, DS7612600000000332, DS7612600000000352, and DS7612600000000342) for plugging and site restoration of 38 orphan gas storage wells in Gratiot and Montcalm counties operated by New Haven Energy LLC, each with proposals due July 21, 2026, restricted to vendors prequalified through prior RFPs and subject to mandatory pre-bid attendance on July 9, 2026. The Mississippi Oil and Gas Board has issued multiple Invitations for Bids for plugging and reclamation of orphaned wells across multiple counties, funded through the Infrastructure Investment and Jobs Act Formula grant program under the Department of the Interior's Orphaned Wells Program.

Recent activity concentrates in Michigan and Mississippi, with scattered opportunities in Texas, Illinois, and Mississippi covering both surface isolation and deep plugging work. The code shows sustained activity in Midwest and Mid-South regions where orphan well inventory and federal funding through IIJA have driven competitive bidding for abandonment services. Michigan's New Haven Energy complex (Gratiot and Montcalm counties) represents the most concentrated recent procurement cluster, with $688,073 estimated for Hillsborough County, Florida water well maintenance and $2.8 million maximum contract value available in San Bernardino County's on-call well and pump maintenance RFQ (SPD126SPDAD6431, due August 31, 2026). Qualification requirements are stringent: bidders must demonstrate five to ten years of direct experience in similar work, hold proper licensing and contractor credentials, comply with prevailing wage mandates, maintain performance and payment bonds, and pass technical scoring on personnel, equipment, methodology, and experience—typically requiring 80-point minimums on 100-point evaluation scales. Set-asides appear limited to service-disabled veteran-owned business status consideration in Michigan procurement and small business set-aside designation in Illinois. The work is capital-intensive, equipment-dependent, and increasingly federally funded, making it most accessible to established contractors with rig capacity, certified personnel, and financial stability to carry bonding and insurance requirements.
