UNSPSC 71121309 Downhole drilling stabilization services is a Commodity code. State and local governments buy well plugging, drilling, and site restoration services under this code, primarily for orphan well abandonment projects funded through federal infrastructure programs. Recent solicitations show Michigan's Department of Environment, Great Lakes, and Energy procuring comprehensive well plugging and site restoration across multiple orphan gas storage well sites in Gratiot and Montcalm counties, with scope spanning rig services (pole, single derrick, and double derrick configurations), casing and tubing rental, drilling equipment, cementing services, mud engineering, wireline services, waste disposal, heavy equipment operations, and site preparation and restoration. The code also encompasses water well maintenance and repair services for potable supply systems, as illustrated by solicitations from San Bernardino County and other utilities for on-call well and pump maintenance. Issuing bodies are predominantly state environmental and natural resource agencies managing federal orphan well programs, county water utilities, municipal water departments, and special districts. Michigan appears as a standout repeat buyer under this code, with four concurrent orphan well plugging solicitations posted in July 2026. Water utilities in California, Florida, Arizona, and other states use the code for routine well maintenance contracts on renewable or on-call bases.
