UNSPSC 71121631: Well redrilling or reworking services

Deepening of an existing oil well or otherwise drilling beyond the extremities (to the side) of the existing well casing or services to perform routine work performed on a well after its completion in order to secure production.

UNSPSC 71121631 Well redrilling or reworking services (Commodity) captures the plugging, abandonment, and site restoration of orphaned oil and gas wells and the repair and rehabilitation of production and municipal water wells. State and local governments buy comprehensive reworking services including mechanical rehabilitation (brushing, airburst treatment), chemical remediation, equipment removal and reinstallation, permit compliance, and associated site preparation and restoration. The Michigan Department of Environment, Great Lakes, and Energy represents the most active recent buyer, issuing four direct solicitations in July 2026 for plugging and restoration of 38 orphaned gas storage wells across three counties. Water district and municipal utilities in Florida, California, Georgia, Mississippi, and Texas also actively solicit under this code for production and potable well rehabilitation, maintenance, and new-well construction. The procuring bodies include state environmental agencies, regional water districts, county utilities departments, and city water utilities, with significant repeat activity from Michigan's orphaned-well remediation program and Florida's county-level water infrastructure operations.

The most visible recent activity centers on Michigan's orphaned well plugging program, where the Michigan Department of Environment, Great Lakes, and Energy solicited four separate direct-bid contracts (posted July 16, 2026, all due July 21, 2026) for plugging and site restoration across New Haven Energy operations in Gratiot and Montcalm counties—totaling 38 wells across four solicitations, each requiring prequalification through prior RFPs and mandatory pre-bid attendance. Representative opportunities outside Michigan include Hillsborough County, Florida's IFB for two-year water well maintenance and repair services on 67 wells (estimated $688,073.00, bids due June 12, 2026); the Mississippi Oil and Gas Board's multiple IFBs for plugging and reclamation of federally funded orphaned wells (bids due April through May 2026); and the Eastern Municipal Water District in California's RFP for on-call well maintenance and rehabilitation services with a five-year contract cap of $2.8 million (proposals due August 31, 2026). Recent activity spans Michigan, Florida, California, Mississippi, Texas, Georgia, and Oregon, with the strongest concentration in Michigan's state-funded orphaned-well program and Florida's county utility operations.
