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, a Commodity code, covers the plugging, abandonment, and site restoration of orphaned and decommissioned oil and gas wells, along with specialized well drilling, reworking, and maintenance services for water supply and irrigation infrastructure. State and local governments procure these services primarily through state energy and environmental agencies managing orphan well remediation programs funded under the Infrastructure Investment and Jobs Act, and through municipal water departments, county utilities, and park districts managing potable water well construction, rehabilitation, and maintenance. Recent solicitations show work spanning the full scope: Michigan's Department of Environment, Great Lakes, and Energy is conducting multiple direct solicitations for plugging and site restoration at orphan gas wells in Gratiot, Montcalm, and Kent Counties, with prequalified vendor pools; the Mississippi Oil and Gas Board is issuing sealed bids for plugging and remediation of orphaned oil and gas wells in multiple counties; and municipal utilities are independently soliciting well drilling, rehabilitation, and maintenance services for water supply and irrigation infrastructure. The mix of issuing bodies reflects both state environmental remediation initiatives (Michigan EGLE, Mississippi Oil and Gas Board) and distributed municipal water and park operators (cities of Albany, Reynolds, Wrens, and Pascagoula in Georgia and Mississippi; counties in Florida, Illinois, and Colorado; water districts and park departments). Work scopes range from new well drilling with pump and electrical systems installation, to color video survey and casing repair, to comprehensive abandonment and site restoration with Davis-Bacon prevailing wage compliance.

Geographic activity centers on Michigan—where multiple direct solicitations for prequalified orphan well work are active across the Lower Peninsula—and Mississippi, with additional recent work posted in Georgia, Florida, Colorado, Illinois, Texas, and Oregon. Representative opportunities include the Michigan Department of Environment, Great Lakes, and Energy's prequalified vendor solicitations for orphan well plugging in Kent, Gratiot, and Montcalm Counties (proposals due July 21, 2026, restricted to prior RFP awardees under direct solicitation format); the Mississippi Oil and Gas Board's IFB for plugging and remediation of nine orphaned wells in Jasper and Jones Counties (bids due December 18, 2026, with mandatory October 22 pre-bid site inspection, Davis-Bacon prevailing wage required, Infrastructure Investment and Jobs Act funding); the City of Albany, Georgia's IFB for Well No. 21 rehabilitation (bids due November 16, 2026); the City of Wrens, Georgia's bid for Well #107 construction funded through State Revolving Fund with Build America, Buy America requirements (bids due September 3, 2026); and the Illinois Department of Natural Resources' IFB for Union County State Fish and Wildlife Area supplemental irrigation well installation under small business set-aside (bids due July 9, 2026, with mandatory pre-bid meeting). Federally funded orphan well programs in Michigan and Mississippi consistently apply Davis-Bacon prevailing wage requirements and restrict bidding to prequalified vendor pools or impose rigorous experience thresholds, with evaluation weighted toward technical capability and equipment adequacy rather than lowest price.
