UNSPSC 71112105: Dipole acoustic logging services

Using two poles of opposite polarity to generate a field, for excitation and detection of shear waves.

UNSPSC 71112105 Dipole acoustic logging services is a Commodity code that shows minimal alignment with recent state and local procurement activity. The code nominally describes geophysical well-logging services using acoustic dipole methods, typically applied in oil and gas or groundwater exploration; however, the recent opportunities posted under this code involve landfill gas collection system construction, irrigation system upgrades, digester gas utilization projects, and municipal executive search services — none of which fall within the scope of acoustic logging or well-characterization work. The mismatch suggests either miscoding in the state and local procurement systems or that this code is not actively used for its intended purpose in current state and local contracting.

The most recent opportunities show issuing bodies spanning special-purpose water and waste authorities (Dalton-Whitfield Solid Waste Authority in Georgia, Eastern Municipal Water District in California) and municipal governments (City of DeBary, Florida; City of College Park, Georgia), posted between January and April 2026. Geographic activity appears concentrated in the Southeast and West Coast. Because the recent opportunities do not represent genuine acoustic logging work, this code does not signal meaningful procurement demand for firms in that service line. Procurement professionals should verify coding before pursuing opportunities tagged to this UNSPSC category, as the actual work being bought does not match the code's technical definition.
