UNSPSC 71112100: Open hole well logging services

The measurement of one or more physical quantities in a well performed through the uncased hole.

UNSPSC 71112100 Open hole well logging services is a Class code that appears to see little relevant recent activity in state and local procurement. The four most recent opportunities tagged to this code span landfill gas collection systems (Dalton-Whitfield Solid Waste Authority, Georgia), park irrigation improvements (City of DeBary, Florida), a digester gas utilization design-build-finance-operate project (Eastern Municipal Water District, California), and municipal executive search services (City of College Park, Georgia). Only the digester gas project involves subsurface gas characterization and measurement work with potential relevance to well logging; the other three solicitations fall outside the nominal scope of open hole well logging services. State and local procurement offices appear to be using this code inconsistently or tagging work that does not require formation evaluation logging, core analysis, or stratigraphic interpretation typical of the classification.

The geographic spread across these opportunities—Georgia, Florida, and California—reflects scattered issuing bodies (special-purpose solid waste and water districts, municipalities) rather than concentrated demand. The sole opportunity with technical relevance to well logging is the Eastern Municipal Water District's February 2026 RFP 26-37 for a 15- or 20-year design-build-finance-own-operate-maintain digester gas utilization agreement at three regional water reclamation facilities in Riverside County, California, with proposals due April 13, 2026, and anticipated contract execution in October 2026. That procurement calls for design and operational work on digester gas projects with documented gas quality and flow characterization, but does not explicitly solicit well logging services. The code does not show active state and local demand for traditional open hole logging work.
