UNSPSC 71121513: Porosity measurement when drilling services

Services to measure the openings in a rock, openings in which petroleum can exist.

UNSPSC 71121513 Porosity measurement when drilling services, a Commodity code, does not align with the recent state and local procurement activity in the source. The code nominally describes well-drilling support services focused on porosity measurement during drilling operations. However, the recent opportunities tagged with this code overwhelmingly concern orphan well plugging, abandonment, site restoration, and water well drilling and rehabilitation work — none of which are primarily porosity-measurement-focused. The Michigan Department of Environment, Great Lakes, and Energy has posted four direct solicitations in July 2026 for orphan gas storage well plugging and site restoration in Gratiot and Montcalm counties (three wells, fourteen wells, nine wells, and twelve wells respectively), all due July 21, 2026, restricted to prequalified vendors, and subject to Davis-Bacon prevailing wage requirements. These solicitations emphasize plugging operations, drilling, re-drilling, site prep, site restoration, equipment rental, labor by classification, waste disposal, and regulatory compliance — a fit that extends well beyond porosity measurement. Additional opportunities include on-call well and pump maintenance by San Bernardino County, water well construction by several Florida municipalities and North Carolina jurisdictions, well rehabilitation by Eastern Municipal Water District in California, and well plugging by the Mississippi Oil and Gas Board and Texas General Land Office. The code sees activity primarily in Michigan, Florida, California, Mississippi, and Texas, with sporadic presence in Illinois, Georgia, Oregon, and other states. Because the recent solicitations reflect broad well construction, rehabilitation, plugging, and abandonment services rather than the specific porosity-measurement-during-drilling scope that the code title suggests, and because the code carries minimal activity volume across state and local jurisdictions, the category shows a fundamental mismatch between its nominal taxonomy and current procurement reality.

The source supports no recent opportunities that directly align with porosity measurement during drilling operations as a primary service objective.
