UNSPSC 71112000: Cased hole well logging services

The measurement of one or more physical quantities in a well performed through a cased hole, includes equipment rental and rental cancellation fees.

UNSPSC 71112000 Cased hole well logging services is a Class code that sees minimal recent activity in state and local procurement aligned with its nominal scope. The code shows little relevant procurement volume under this tier, as the recent opportunities tagged to it diverge substantially from cased hole well logging work and instead span landfill gas collection infrastructure, park irrigation systems, wastewater digester gas utilization, and municipal executive recruitment — none of which constitute well logging services. The single opportunity with tangential relevance to subsurface infrastructure is the Dalton-Whitfield Solid Waste Authority's landfill gas collection and control system expansion, which involves surveying and installing gas extraction wells with HDPE casing and associated horizontal collectors and piping, but does not involve logging services in the well-logging sense.

The Dalton-Whitfield Solid Waste Authority issued an ITB (PE75552NONST2026000000061) on April 17, 2026, for construction and installation of landfill gas extraction infrastructure at the Old Dixie Highway Municipal Solid Waste Landfill in Dalton, Georgia, with a bid deadline of May 21, 2026, and a mandatory pre-proposal conference on May 1, 2026. Qualified contractors must hold a Georgia general contractor license, demonstrate a minimum of five years' experience in landfill gas collection and control system construction, and have successfully completed at least five similar or larger projects within the past five years, performing a minimum of 50 percent of labor on-site. Work encompasses approximately 4,100 linear feet of 6-inch perforated horizontal collectors, 7,420 linear feet of lateral piping in multiple diameters, 3,660 linear feet of liquid conveyance lines, 3,170 linear feet of 2-inch air supply lines, 25 liquefied fossil gas wellheads, and associated appurtenances and controls. The procurement shows no set-aside designations and requires compliance with the Georgia Security and Immigration Compliance Act. Geographic activity under this code is limited; the available opportunities reflect scattered state and local issuance in Georgia, Florida, and California rather than concentrated procurement activity, and the code does not support reliable projections of ongoing or future demand in the cased hole well logging space.
