UNSPSC 71121302: Downhole drilling borehole enlargement services

Services to increase the size of the borehole part of directional or performance drilling services.

UNSPSC 71121302 Downhole drilling borehole enlargement services is a Commodity code that captures well plugging, abandonment, and site restoration services for orphan oil and gas wells and municipal water infrastructure projects. State and local governments procure under this code when decommissioning aged or non-productive wells and rehabilitating municipal groundwater systems. Recent solicitations reveal a mix of work: the Michigan Department of Environment, Great Lakes, and Energy has posted four direct solicitations in July 2026 for plugging and site restoration of 38 orphan gas storage wells across Gratiot and Montcalm counties (responses due July 21, 2026, RFP format with mandatory pre-bid meetings). The Mississippi Oil and Gas Board has issued multiple invitations for bids on orphan well plugging and remediation across state counties under the Orphaned Wells Program funded through the Infrastructure Investment and Jobs Act. Municipal water utilities—Marion County, Florida; Sarasota County, Florida; Hillsborough County, Florida; and Seminole County, Florida—have posted work for well abandonment, maintenance, and repair services. These solicitations stress prevailing wage compliance, Davis-Bacon Act applicability, and federal funding pass-through requirements where IIJA or federal grant dollars support the work.

The issuing bodies mix state environmental agencies managing orphan well remediation, county and municipal water utilities managing production and monitoring wells, and special-purpose authorities. Michigan's EGLE dominates recent orphan-well activity with four concurrent direct solicitations; Mississippi's Oil and Gas Board runs a parallel program; and Florida water departments (Marion, Sarasota, Hillsborough, Seminole counties and the City of Cocoa Beach area) lead municipal well work. Recent geographic concentration appears in Michigan (Gratiot and Montcalm counties), Mississippi (statewide), and Florida (Panhandle and Central regions). Representative opportunities include the Michigan Department of Environment, Great Lakes, and Energy's Orphan Well New Haven Sec 3 (3) Wells direct solicitation (DS7612600000000322, due July 21, 2026, prequalified vendors only, unit-price RFP format with 68 line-item Schedule B); Sarasota County's well abandonment RFQ for a single residential property (2026QQ759, due July 10, 2026, IFB format, $50,000 ceiling); and Seminole County's wastewater pump station R&R master services agreement (CC710026HSMA, due August 5, 2026, IFB format, 24-hour emergency response required, three-year initial term with two optional renewals). The code sees steady activity driven by federal orphan-well remediation funding and routine municipal groundwater asset management.
