UNSPSC 71121518: Well site geology services

Services provided at well site during the course of the drilling phase, including identifying and monitoring well drilling progress and supporting well directional steering, through evaluation of the physical formation structure (cuttings analysis) at the time.

UNSPSC 71121518 Well site geology services is a Commodity code. State and local governments procure well site geology services primarily through orphaned oil and gas well plugging, abandonment, and remediation contracts—work that blends geology, geotechnical site characterization, and field supervision. Recent state and local solicitations show that the code captures drilling support, site assessment, and technical oversight for municipal water well rehabilitation and replacement projects, though the bulk of recent activity centers on environmental remediation of abandoned oil and gas infrastructure financed through state orphan well programs and federal IIJA funding.

Four consecutive weeks of activity from the Michigan Department of Environment, Great Lakes, and Energy (EGLE) dominate the current market. EGLE posted four direct solicitations in late June and mid-July 2026—spanning 38 orphaned gas storage wells across Gratiot and Montcalm counties operated by New Haven Energy LLC—all with July 21, 2026 response deadlines (Solicitation Nos. DS7612600000000322, DS7612600000000332, DS7612600000000352, and DS7612600000000342). Each notice restricts bidding to vendors prequalified through five prior EGLE RFPs and requires attendance at mandatory pre-proposal meetings on July 9, 2026. Work scope includes plugging, site restoration, Davis-Bacon prevailing wage compliance, and unit-price scheduling across 68 line items per well. Beyond Michigan, the Mississippi Oil and Gas Board and the Texas General Land Office are active, with multiple orphan well plugging ITBs posted March through May 2026 spanning six counties in Mississippi and statewide work in Texas. Water well maintenance and drilling also appear: Hillsborough County (Florida) released an ITB for 67-well maintenance across county parks (June 12, 2026 response), and Seminole County (Florida) solicited wastewater pump station repair services with well-maintenance parallels (July 21, 2026 response). Well drilling and construction appears in Marion County and Palm Bay (Florida), the City of Watertown (Wisconsin), and Collier County (Florida)—a scatter of repair and new-construction RFPs concentrated in the Southeast. The code shows little recent activity outside of oil and gas remediation and public water-supply infrastructure, with modest municipal well drilling and rehabilitation work spread across Florida, the upper Midwest, and scattered state agencies. Set-asides include Small Business designations in Illinois and service-disabled veteran consideration in Michigan; most other procurements are open to qualified licensed contractors.
