UNSPSC 71121202: Core isolation services

Services to isolate the core in order to bring to it the surface.

UNSPSC 71121202 Core isolation services is a Commodity code. State and local governments use this code to procure well plugging, abandonment, remediation, and site restoration services—comprehensive work to decommission orphaned, damaged, or end-of-life water and gas wells. The code spans plugging operations (cement placement, casing installation, pressure testing), removal of well equipment and surface infrastructure, site cleanup and grading, environmental compliance, and specialized services such as wireline operations, geophysical logging, and aquifer performance testing. Recent solicitations show that state environmental agencies, county water utilities, municipal water departments, and special-purpose districts issue most opportunities, with repeat activity from state oil and gas boards managing federally funded orphan well programs and municipal water systems managing aging infrastructure.

Michigan's Department of Environment, Great Lakes, and Energy dominates recent activity with four concurrent direct solicitations (posted June 29 and July 16, 2026) for orphan gas well plugging across Gratiot and Montcalm counties—26 wells total across four site sections—due July 21, 2026. All four are prequalified-vendor procurements (IFB structure) requiring prior award through five specified RFPs and mandatory pre-bid attendance on July 9, 2026, with Davis-Bacon prevailing wage compliance and unit-price bidding on 68-line Schedule B matrices. Additional representative opportunities span water well rehabilitation (Hillsborough County, Florida, $688,073 two-year contract for 67 well maintenance, posted May 19, 2026; City of Bend, Oregon, RFP for River Well #1 engineering and rehabilitation, $525,000 design scope, posted March 30, 2026), orphan oil and gas well plugging across five Mississippi counties under federal IIJA funding (Mississippi Oil and Gas Board, three separate IFBs for 17 total wells, April–May 2026 deadlines), and specialized work including aquifer storage and recovery retrofits (City of Santa Cruz, Beltz 9 ASR conversion design, posted March 30, 2026) and landfill gas collection system expansion (Dalton-Whitfield Solid Waste Authority, Georgia, ITB, May 21, 2026). Geographic concentration spans Michigan, Florida, Mississippi, Texas, California, Oregon, Georgia, and Illinois; federal Infrastructure Investment and Jobs Act orphan well funding drives significant activity in Mississippi and Texas. The code shows active, specialized procurement demand with moderate incumbent-barrier thresholds (prequalification or relevant experience minimums) and strong prevailing wage and federal compliance requirements.
