UNSPSC 71121008: Oilwell lost circulation services

A service performed to control a loss of drilling fluid to a formation, usually caused when the hydrostatic head pressure of the column of drilling fluid exceeds the formation pressure.

UNSPSC 71121008 Oilwell lost circulation services (Commodity) does not reflect the work state and local governments are actually buying under this code. Recent solicitations tagged with 71121008 span water well drilling, irrigation system installation, wastewater pump station repair, well maintenance, and orphan oil and gas well plugging—none of which are oilwell lost circulation services in the traditional sense. The code's nominal scope describes materials or additives that seal lost circulation zones in producing wells; the recent opportunities instead cover water supply infrastructure, municipal well rehabilitation, and environmental remediation of abandoned wells, primarily at state environmental or natural resources agencies, counties, cities, and special districts.

State and local issuing bodies running these solicitations include the Michigan Department of Environment, Great Lakes, and Energy (multiple prequalification and direct solicitations for orphan well plugging across the Lower Peninsula), the Mississippi Oil and Gas Board (nine and ten well plugging packages under IFB), Hillsborough County in Florida (well maintenance contracts), Seminole County in Florida (wastewater pump station repair), the City of Albany in Georgia (well rehabilitation), the Illinois Department of Corrections (well casing surveys and repair at Sheridan Correctional Center), and smaller municipalities in Florida, Georgia, and other states issuing ITBs and RFQs for water infrastructure projects. The code shows substantial activity concentrated in Michigan orphan well remediation, followed by water well construction and maintenance work across the Southeast and Midwest. Recent representative opportunities include the Michigan EGLE's prequalification RFP for Oil & Gas Services FY26 4th Quarter (RFP posted August 25, 2026, proposals due September 22, 2026) awarding five contractors a cumulative $800,000 over one year and five months; the Mississippi Oil and Gas Board's IFB for plugging nine orphaned wells in Jasper and Jones Counties (bids due December 18, 2026, with mandatory pre-bid October 22, 2026); and Hillsborough County's ITB 26-00234 for water well maintenance and repair services across 67 county wells estimated at $688,073 for two years, bids due June 12, 2026. The code shows activity across Michigan, Mississippi, Florida, Georgia, Illinois, and scattered smaller jurisdictions, with the highest frequency in states with significant orphan well or groundwater remediation programs.
