UNSPSC 71122100: Oilfield sand control services

The installation of equipment or application of techniques to prevent migration of reservoir sand into the wellbore or near-wellbore area to maintain the structure of the reservoir around the wellbore.

UNSPSC 71122100 Oilfield sand control services, a Class code, encompasses plugging, abandonment, and site restoration of orphaned oil and gas wells, along with well maintenance and rehabilitation services procured by state environmental agencies, county governments, and special-purpose districts. State and local buyers issue direct solicitations and invitations for bid targeting prequalified contractors to perform comprehensive well plugging under prevailing wage requirements, with scope items including drilling equipment rental, cementing services, wireline operations, site preparation, and restoration. The Michigan Department of Environment, Great Lakes, and Energy issued four consecutive direct solicitations in mid-July 2026 for orphan well plugging across Gratiot and Montcalm counties—covering 3, 14, 9, and 12 wells respectively—all with proposals due July 21, 2026, restricted to contractors prequalified through prior RFP processes, and evaluated on key personnel qualifications, business-owned equipment, technical experience, and vendor questions on a 100-point scale with 80-point minimums for award consideration. The Mississippi Oil and Gas Board and Texas General Land Office have also posted multiple orphaned-well plugging solicitations funded through Infrastructure Investment and Jobs Act formula grants, requiring Davis-Bacon prevailing wage compliance and targeting contractors with five-plus years of documented experience in similar work.

Recent activity concentrates in Michigan, Mississippi, and Texas, with the largest volume of active solicitations in Michigan during July 2026. Beyond orphan-well plugging, the code also captures on-call water-well maintenance and repair services, such as the San Bernardino County Department of Public Works' $2.8 million five-year contract for well and pump maintenance across 32 county wells and booster stations, Eastern Municipal Water District's request for well maintenance and rehabilitation services on an as-needed basis in California, and Hillsborough County's $688,073 two-year water well maintenance contract for 67 irrigation and potable wells. Well construction procurement appears in Florida (Marion County's four new potable wells, Sarasota County's well abandonment, Palm Bay's four production wells) and a few other states (Illinois, Oregon), typically as smaller discrete projects rather than statewide programs. Issuing bodies span state oil-and-gas regulators, county utilities departments, cities, and water districts. The code shows sustained, multi-state activity driven by federal orphan-well remediation funding and routine utility maintenance needs, with response deadlines clustering in spring-summer 2026 and prequalification requirements common among larger state programs.
