UNSPSC 71121514: Resistivity measurement when drilling services

The recording of the resistance of formation water to natural or induced electrical current.

UNSPSC 71121514 Resistivity measurement when drilling services (Commodity) covers measurement and monitoring work conducted during well drilling and abandonment operations, including resistivity surveys, wireline services, video logging, and geophysical evaluation—work that state and local governments procure primarily as part of broader well construction, rehabilitation, and orphan well plugging projects. The code's recent activity shows heavy concentration in orphan and abandoned well programs, particularly in Michigan, Mississippi, and Florida, where drilling services bundled with measurement capabilities are essential to abandonment compliance and site restoration. State and local issuing bodies acquiring this work span state environmental departments, county authorities, municipal utilities, and water districts, with Michigan's Department of Environment, Great Lakes, and Energy emerging as a dominant repeat buyer in the recent quarter. Representative solicitations include the Michigan Department of Environment, Great Lakes, and Energy's orphan well plugging RFPs for the New Haven Energy gas storage field (direct solicitations DS 260000000032 through DS 260000000035, posted July 16, 2026, with proposals due July 21, 2026), each naming wireline services, mud engineering, and geophysical logging as line-item cost components within broader 68-item pricing matrices; the Illinois Department of Natural Resources' Union County supplemental irrigation well installation (IFB 26-422DNR-LNDMG-B-52982, posted June 17, 2026, bids due July 9, 2026); Sarasota County's well abandonment RFQ (solicitation 2026QQ759, posted July 2, 2026, quotes due July 10, 2026); and the Mississippi Oil and Gas Board's multi-well orphan well plugging solicitations (IFBs RFx 3160007881, 3160007966, and 3160007967, issued March through May 2026).

The geographic spread spans Michigan (dominant in Q2–Q3 2026 orphan well activity), Mississippi (seven to fourteen wells per orphan-well IFB), Florida (Sarasota, Seminole, Hillsborough, Marion, Collier, and Volusia County utilities), Texas (Railroad Commission statewide well plugging and Texas General Land Office high-H₂S well maintenance), California (Eastern Municipal Water District well maintenance and digester gas utilization projects), and scattered municipal utilities in Wisconsin, Oregon, Georgia, Colorado, and Illinois. The recent opportunities reflect a surge in federally funded orphan well remediation under the Infrastructure Investment and Jobs Act, with Davis-Bacon prevailing wage compliance, quality assurance testing, and regulatory documentation now standard line-item expectations. Bidders pursuing this code should expect prequalification requirements (Michigan's five prior RFP awards; Mississippi's five-year experience threshold), mandatory pre-bid attendance, unit pricing across 50–70 line items, firm pricing with no escalation clauses, and evaluation weighted toward key personnel (25%), business-owned equipment (25%), technical experience (25%), and vendor responsiveness (25%), with 80-point technical minimums typical. Work is concentrated in Q2–Q3 2026 and anticipated to remain steady through 2027 as state and federal orphan well budgets execute; contractors should confirm Davis-Bacon compliance, wireline and geophysical testing certifications, and mobilization capacity for multi-well, multi-jurisdiction campaigns.
