UNSPSC 71121516: Surveying wireline services

Services for measurement of formation properties with electrically powered instruments to infer properties and make decisions about drilling and production operations.

UNSPSC 71121516 Surveying wireline services is a Commodity-tier code covering specialized downhole assessment and intervention services for oil and gas wells, water wells, and geothermal boreholes. State and local governments procure wireline work as a subset of larger well abandonment, plugging, rehabilitation, and maintenance contracts — the wireline operator deploys cable-suspended tools to measure well conditions, retrieve data, perform mechanical interventions (such as perforating or setting packers), and support cementing and well-sealing operations. Recent solicitations show the Michigan Department of Environment, Great Lakes, and Energy issuing multiple direct solicitations in July 2026 for orphan gas storage well plugging across Gratiot and Montcalm Counties, each pricing wireline services as a line item within comprehensive 68-item rate matrices. The scope of work is narrowly technical: operators and riggers perform cable deployment, tool manipulation, geophysical measurement, and mechanical assists during plugging sequences. Wireline is almost never the prime contract focus; it appears alongside rig services, drilling fluids, cementing, heavy equipment, and labor across multiple classifications under prevailing wage (Davis-Bacon) requirements.

Issuing bodies soliciting under this code are primarily state environmental and natural resources agencies managing orphaned well remediation (Michigan EGLE), water utilities handling well rehabilitation (Eastern Municipal Water District in California, San Bernardino County, Seminole County and Hillsborough County in Florida), and less frequently municipal water departments procuring routine well maintenance. The Michigan orphan well solicitations dominate recent activity, with four separate direct solicitations posted June 29 and July 16, 2026, spanning 26 total gas storage wells across two counties—each restricted to vendors prequalified through prior RFPs and requiring mandatory pre-bid attendance on July 9, 2026. Geographic concentration is heavy in Michigan (Gratiot and Montcalm Counties) and California (Riverside County); secondary activity appears in Florida (Seminole, Hillsborough, Marion, Sarasota, Collier counties), Texas, Mississippi, Illinois, and the Pacific Northwest. The Michigan direct solicitations (DS7612600000000321 through DS7612600000000352, all due July 21, 2026) represent the most current and active concentration of wireline procurement.
