UNSPSC 71121504: Density measurement when drilling services

Measurement of the bulk density of the formation when drilling.

UNSPSC 71121504 Density measurement when drilling services, a Commodity code, covers well abandonment, plugging, and site restoration work that state and local governments procure for orphaned oil and gas wells, municipal water supply infrastructure renewal, and environmental remediation. Recent solicitations show state environmental agencies, water utilities, counties, and special-purpose districts issuing direct solicitations, invitations for bid, and requests for proposal for well drilling, pump installation, plugging, and related subsurface services. The Michigan Department of Environment, Great Lakes, and Energy has posted four concurrent direct solicitations in July 2026 for orphan gas storage well plugging across Gratiot and Montcalm counties—covering 38 total wells with mandatory prequalification through prior RFPs and prevailing wage compliance under Davis-Bacon requirements. Pricing is unit-based across 68 line items for labor, equipment, materials, and site restoration, with technical evaluation weighted on key personnel, business-owned equipment, company experience, and vendor responses. The Sarasota County, Florida procurement for single-family residential well abandonment (quote ceiling $50,000, due July 10, 2026) and the Illinois Department of Natural Resources supplemental irrigation well installation for Union County State Fish and Wildlife Area (small-business set-aside, bid extended to July 9, 2026) illustrate the diversity of issuing bodies and project scales under this code.

Recent activity concentrates in Michigan, Florida, and Texas, with secondary volume in Mississippi, California, and the upper Midwest. The Michigan orphan well cluster alone spans four separate direct solicitations posted within days of each other in late June and mid-July 2026, all with July 21 response deadlines and identical prequalification and prevailing wage structures. Sarasota County's well abandonment RFQ (July 2–10, 2026) and Marion County, Florida's four-well construction procurement (due May 21, 2026) anchor Florida activity; both require environmental liability insurance and regulatory compliance with Florida Department of Environmental Protection standards. The Texas General Land Office RFQ for high hydrogen sulfide well services (due May 5, 2026) and the Railroad Commission statewide well plugging RFQ for orphaned wells demonstrate Texas-level procurement demand. Mississippi Oil and Gas Board has issued multiple IFBs for well plugging under federal IIJA funding (three solicitations posted March–April 2026, response windows April 13–April 28, 2026), all requiring five-year minimum experience and federal Buy America compliance. The issuing-body mix spans state environmental and energy regulators, county utilities departments, municipal water authorities, and special districts; repeat buyers include the Michigan Department of Environment, Great Lakes, and Energy (four concurrent solicitations in the recent block) and Mississippi Oil and Gas Board (three concurrent procurements). Contracting vehicles include direct solicitation with prequalification lists, competitive sealed-bid IFBs, and qualifications-based RFPs; most require mandatory pre-bid meetings, unit-price or lump-sum pricing, comprehensive insurance (general liability, workers' compensation, pollution liability), and Davis-Bacon or state prevailing wage compliance where federal funding applies. Liquidated damages, performance bonds, and equipment lists are standard contract terms for well construction and plugging work under this code.
