UNSPSC 71151503: Hydrocarbon allocation, accounting, and measurement audits

The process of auditing to identify errors, issues, or weaknesses with the operation and maintenance of the hydrocarbon measurement system.

UNSPSC 71151503 Hydrocarbon allocation, accounting, and measurement audits (Commodity) encompasses well plugging, abandonment, and site restoration services for orphaned oil and gas wells, which state and local governments—particularly state environmental and natural resources departments, county industrial authorities, and special-purpose district authorities—are actively soliciting. The code captures the full scope of work involved in decommissioning unproductive or abandoned wells: drilling, re-drilling, plugging, cementing, well casing and tubing removal, wireline services, waste disposal, site preparation, and post-abandonment site restoration including equipment removal and landscape grading. Recent opportunities show that state and local buyers are procuring these services under the Infrastructure Investment and Jobs Act orphaned wells program and state-funded environmental remediation initiatives, with the Michigan Department of Environment, Great Lakes, and Energy and the Mississippi Oil and Gas Board as standout repeat buyers in mid-2026.

Michigan's four concurrent direct solicitations (posted mid-July 2026 with July 21 response dates) target plugging and restoration of 38 orphaned gas storage wells across Gratiot and Montcalm counties in the New Haven Energy operating area, with contracts restricted to prequalified vendors from prior RFPs and mandatory pre-bid attendance required. Mississippi's multiple concurrent IFBs (issued March–April 2026) seek plugging of seven-well packages across five counties under federally funded contracts with May-through-June response windows. The Texas General Land Office has issued RFQ 455-26-1020 for high-pressure H₂S well services statewide. All solicitations require Davis-Bacon prevailing wage compliance, comprehensive unit pricing for 68+ line items covering labor, equipment, materials, and specialized services, and evaluation on technical merit (key personnel, business-owned equipment, company experience, vendor questions) rather than low price alone. Geographic concentration is heaviest in Michigan and Mississippi, with secondary activity in Texas and scattered opportunities in Illinois and Florida. Prequalification and prior performance history are critical barriers to entry; vendors must already hold state-approved contracts or demonstrated experience to compete.
