UNSPSC 71121511: Mud logging services

Services for the analysis of materials brought to the surface during the drilling of an oil or gas well, and the analysis of certain mechanical and fluid parameters relating to the drilling process.

UNSPSC 71121511 Mud logging services, Commodity tier, encompasses well plugging, abandonment, and site restoration for orphaned oil and gas wells — the primary work being solicited under this code in recent state and local activity. State and local governments are procuring comprehensive well abandonment services including drilling, casing installation, cementing, waste disposal, heavy equipment operation, and site restoration through direct solicitations and invitation-to-bid notices. The Michigan Department of Environment, Great Lakes, and Energy dominates recent activity, issuing four related direct solicitations in July 2026 for orphan gas storage well plugging across Gratiot and Montcalm counties (38 wells total) with July 21, 2026 response dates and Davis-Bacon prevailing wage compliance required. Mississippi's Oil and Gas Board, the Texas General Land Office, and the Illinois Department of Natural Resources have also posted orphan well plugging solicitations, along with Florida counties (Seminole, Sarasota, Marion) and other municipalities soliciting water well maintenance, rehabilitation, and construction services under related codes.

Geographic concentration centers on Michigan (multiple large orphan well programs), Mississippi (multiple IIJA-funded well abandonment contracts), Florida (water well rehabilitation and construction), and Texas (oil and gas well plugging statewide), with additional activity in Illinois, California, Georgia, and Oregon. Representative current opportunities include the Michigan Department of Environment, Great Lakes, and Energy's direct solicitation for three orphan wells in Gratiot County (Solicitation DS7612600000000322, due July 21, 2026, direct solicitation with mandatory pre-bid July 9); the Mississippi Oil and Gas Board's IFB for seven well plugging projects across five counties (IFB 3160007967, due May 11, 2026); Hillsborough County, Florida's ITB for water well maintenance and repair services at 67 wells (ITB 26-00234, $688,073 estimated value, due June 12, 2026); and Eastern Municipal Water District's RFP for well maintenance and rehabilitation services in California (RFP 3931, due April 24, 2026, five-year term, minimum two awards). These solicitations are predominantly driven by infrastructure investment priorities, orphan well remediation funded through federal IIJA grants, and routine municipal water system maintenance.
