UNSPSC 71122407: Drill stem testing services

Tests for reservoir pressure, permeability, skin, or productivity, downhole pressure measurements to determine reservoir characterization.

UNSPSC 71122407 Drill stem testing services is a Commodity code that maps poorly to the recent state and local procurement activity in the source data. The code nominally describes drill stem testing — a specialized pressure-measurement and flow-characterization service performed during oil and gas well operations — yet the recent opportunities tagged under it consist almost entirely of orphan well plugging, abandonment, and site restoration services, which are remedial closure activities, not production-phase testing. The Michigan Department of Environment, Great Lakes, and Energy has posted four nearly concurrent direct solicitations in July 2026 for plugging, drilling, and site restoration at 26 total orphan gas storage wells across Gratiot and Montcalm counties. The Illinois Department of Natural Resources issued an IFB in June 2026 for well drilling and pump installation at Union County State Fish and Wildlife Area. The Mississippi Oil and Gas Board issued multiple IFBs in March and April 2026 for orphaned well plugging and remediation across seven to twelve wells per solicitation. The Texas General Land Office posted an RFQ in May 2026 for high hydrogen sulfide well plugging services. These solicitations share scope elements — well abandonment, plugging, site restoration, Davis-Bacon prevailing wage compliance, and federal funding through the Infrastructure Investment and Jobs Act — but the code's nominal focus on drill stem testing operations during production does not align with the closure-phase work actually being procured.

Geographic activity concentrates in Michigan (Gratiot and Montcalm counties), Mississippi (multiple counties), Texas (statewide), and Illinois (Union County), with sporadic activity in Florida and other jurisdictions for distinct well-related services (maintenance, pump station repair, water well construction) that fall outside the drill stem testing frame. The issuing bodies are state environmental and natural resources agencies, state oil and gas regulators, and a few local water utilities. A representative recent opportunity is the Michigan Department of Environment, Great Lakes, and Energy's direct solicitation DS7612600000000322 for plugging three orphan wells in Gratiot County, due July 21, 2026, restricting bidders to vendors prequalified through prior RFPs, with unit-price line-item pricing, Davis-Bacon wage requirements at $39.57–$41.28 per hour plus $25.00–$40.00 fringe, and technical evaluation on key personnel, equipment, experience, and questionnaire responses. The code shows substantial recent volume but signals a mismatch between its intended scope and the actual work being solicited; firms pursuing this code should clarify whether they offer plugging and remediation services rather than drill stem testing.
