UNSPSC 71121201: Conventional coring services

Services to remove core sample from the wellbore.

UNSPSC 71121201 Conventional coring services is a Commodity code that encompasses well drilling, plugging, abandonment, and site restoration work for orphaned and abandoned oil and gas wells, as well as municipal water well construction, rehabilitation, and maintenance. State and local governments procure under this code primary through state departments managing oil and gas or environmental resources, municipal water utilities, counties, and special-purpose water districts. The Michigan Department of Environment, Great Lakes, and Energy leads recent activity with four direct solicitations posted in mid-July 2026 for orphan well plugging across Gratiot and Montcalm counties—encompassing 38 total gas storage wells operated by New Haven Energy LLC—all due July 21, 2026 under IFB format with mandatory pre-proposal meetings and prequalification requirements through prior RFPs. Work is subject to Davis-Bacon prevailing wage compliance, unit-price schedules with 68 standardized line items covering labor classifications, equipment rental, drilling services, cementing, wireline operations, waste disposal, and site restoration. Scope varies from three-well to fourteen-well projects with pricing matrices, detailed timelines segmented into site prep, mobilization, plugging, and restoration phases, and firm fixed-rate structures with no change-order authority absent state approval.

Recent opportunities cluster heavily in Michigan (orphan well plugging), Florida (municipal well maintenance, rehabilitation, and construction at Seminole County, Sarasota County, Hillsborough County, Marion County, and Palm Bay), Illinois (state fish and wildlife area well and pump installation), Mississippi (orphan well plugging through the Oil and Gas Board under federal Infrastructure Investment and Jobs Act funding), Texas (water treatment plant design services and H2S well services), California (on-call well maintenance and digester gas utilization), and Georgia (monitoring well replacement and McIntosh County deep well installation). Illinois Department of Natural Resources, Sarasota County, Hillsborough County, Seminole County, Palm Bay, Marion County, Eastern Municipal Water District, and the Mississippi Oil and Gas Board are repeat issuing bodies. Representative solicitations include the Michigan EGLE orphan well plugging RFPs (direct solicitation format, July 21 response, prequalified vendor pools), Hillsborough County's two-year water well maintenance contract (ITB, June 12 response, $688,073 estimated value), Seminole County wastewater pump station services (IFB, August 5 response, master service agreement with three-year initial term), and the Mississippi Oil and Gas Board's orphan well plugging IFBs (federal IIJA funding, April response windows). Geographic concentration reflects infrastructure renewal in Florida water systems, federally funded orphan well remediation across the Mississippi Delta and Great Lakes regions, and municipal water supply upgrades in the Southwest and Upper Midwest.
