UNSPSC 71121200: Coring services

Services to remove core sample from the wellbore.

UNSPSC 71121200 Coring services is a Class code covering well drilling, well plugging, well rehabilitation, and related subsurface access work that state and local governments buy to maintain water supply infrastructure, manage orphaned or abandoned wells, and support remediation and monitoring activities. The code's recent activity reflects substantial demand for orphan well plugging driven by federal infrastructure funding, water well maintenance and repair for municipal and county systems, and specialized services including well video surveys, casing repair, and exploratory drilling for water exploration and storage facilities.

State and local buyers under this code span water districts and utilities, county and city public works and parks departments, state environmental and natural resources agencies, and state corrections facilities. Michigan's Department of Environment, Great Lakes, and Energy (EGLE) is the most active repeat buyer in the recent dataset, issuing multiple prequalification and direct solicitations for orphan well plugging across the Lower Peninsula under federal Infrastructure Investment and Jobs Act funding; Mississippi's Oil and Gas Board similarly solicits orphan well plugging services; and counties in Florida (Hillsborough, Sarasota, Escambia), Georgia (Gwinnett), Illinois, Colorado (Boulder), and California (San Bernardino) post maintenance, repair, and installation work. Representative recent opportunities include EGLE's August 2026 RFP for prequalification of oil and gas well plugging contractors (RFP7612600000025221, proposals due September 22, 2026) with five-year contract terms and anticipated quarterly rolling RFQs for individual project packages; the Mississippi Oil and Gas Board's October 2026 IFB for plugging and remediation of nine orphaned wells in Jasper and Jones Counties (RFx 3160008162, bids due December 18, 2026, with mandatory pre-bid site inspection October 22); and Hillsborough County's May 2026 ITB for water well maintenance and repair services across 67 irrigation and potable wells at an estimated $688,073 over two years (ITB-26-00234, bids due June 12, 2026). Geographic concentration is strongest in Michigan, Mississippi, and Florida, with secondary activity in Georgia, Illinois, Colorado, Texas, Oregon, and California. The code shows steady demand driven by aging municipal water infrastructure, federal orphan-well remediation funding, and routine maintenance cycles at county and city utility systems.
