UNSPSC 71121627: Steerable underreaming while well drilling services

Services using steerable tools to enlarge a wellbore past its original drilled size.

UNSPSC 71121627 Steerable underreaming while well drilling services, a Commodity code, encompasses the specialized drilling technique of enlarging wellbores using steerable tools during well construction—a service state and local governments buy primarily for orphan well plugging, remediation, and site restoration on gas storage fields. Recent solicitations show this code tagged to large batch well-abandonment projects where state environmental agencies manage legacy wells, though the actual drilling work solicited spans broader plugging and site restoration scopes rather than steerable underreaming alone. The Michigan Department of Environment, Great Lakes, and Energy has dominated recent activity with four direct solicitations in July 2026 covering 38 orphan gas storage wells across Gratiot and Montcalm counties—three wells (New Haven Sec 3), 14 wells (Sec 4), 12 wells (Sec 5-10 & Plank 1-1), and nine wells (Sec 31-33)—all on direct solicitation (DS) basis with July 21, 2026 response dates. All four solicitations required prequalification through prior RFPs and mandatory pre-proposal meetings; bidders must submit unit pricing across 68 line items covering labor, equipment, materials, and specialized services, with Davis-Bacon prevailing wage requirements and technical evaluation weighted on personnel qualifications (25%), equipment ownership (25%), experience and ability (25%), and vendor response quality (25%), with 80-point minimum thresholds. Beyond Michigan, orphan well work appears sporadically: Mississippi Oil and Gas Board issued multiple IFBs for well plugging and reclamation across seven to ten scattered wells; the Texas General Land Office and Railroad Commission solicited statewide well plugging frameworks; and Illinois Department of Natural Resources procured single-well installations. The code shows little recent activity outside orphan well abandonment programs, with the geographic concentration heavily in Michigan and Mississippi in July and March 2026, followed by scattered activity in Texas, Illinois, Florida, and Oregon. Most solicitations emphasize Davis-Bacon compliance, site mobilization and demobilization, waste disposal, and environmental remediation alongside drilling operations—suggesting that state and local governments use this code to tag broad well service work rather than steerable underreaming as a discrete specialty. Firms pursuing this category should prioritize orphan well prequalification programs in states with large legacy well inventories and IIJA/Infrastructure Investment and Jobs Act funding, particularly Michigan's New Haven formation fields and Mississippi's statewide programs, where batch solicitations create higher deal velocity than individual well projects.
