UNSPSC 71122110: Gravel carrier fluid sand control services

This is a broad category which could include any type of fluid designed specifically to provide the necessary viscosity or carrying capacity for transporting resieved gravel or proppant down the well and into the annulus.

UNSPSC 71122110 Gravel carrier fluid sand control services is a Commodity code that state and local governments use to classify well plugging, abandonment, and site restoration services for orphaned oil and gas wells and municipal water well infrastructure projects. Recent solicitations show that state and local buyers are predominantly focused on orphan well remediation—plugging abandoned wells, removing equipment, and restoring sites to regulatory compliance—rather than the code's nominal description. The Michigan Department of Environment, Great Lakes, and Energy has issued four direct solicitations in July 2026 for plugging and site restoration at 26 total orphan gas storage wells in Gratiot and Montcalm counties, all with proposals due July 21, 2026. These are representative of the largest recent concentration of activity under this code. Work includes comprehensive site supervision, labor across multiple classifications, rig services, well casing and tubing rental, drilling equipment, cementing services, mud engineering and fluids, wireline services, waste disposal, heavy equipment operations, site preparation, and restoration. Davis-Bacon prevailing wage requirements apply. Beyond Michigan, recent opportunities span municipal water well construction and rehabilitation (Hillsborough County, Florida; Collier County, Florida; City of Palm Bay, Florida; Marion County, Florida), state oil and gas board orphan well programs (Mississippi Oil and Gas Board; Texas General Land Office; Railroad Commission of Texas), and specialized well and pump maintenance contracts (Eastern Municipal Water District, California; San Bernardino County, California). The issuing bodies include state environmental and natural resources departments, county utilities departments, cities, special districts, and state oil and gas regulatory boards.

Activity is concentrated in Florida (Hillsborough, Collier, Marion, Sarasota, Seminole counties and the cities of Bend and Pascagoula), Michigan (Department of Environment, Great Lakes, and Energy), Mississippi (Oil and Gas Board), Texas (General Land Office and Railroad Commission), and California (Eastern Municipal Water District and San Bernardino County). Orphan well plugging solicitations are most active in Michigan, Mississippi, and Texas, where state programs are actively remediating abandoned wells through federal Infrastructure Investment and Jobs Act funding. Water well construction and rehabilitation opportunities are geographically dispersed but concentrated in the Southeast and Southwest. The Michigan Department of Environment, Great Lakes, and Energy is a standout repeat buyer, with four major direct solicitations posted in July 2026 alone; all require prequalification through prior RFPs and mandatory pre-bid attendance. Hillsborough County and Seminole County in Florida are also repeat issuers, with Hillsborough soliciting well maintenance and repair services for 67 irrigation and potable water wells under ITB 26-00234 (due June 12, 2026, estimated value $688,073 for two years) and Seminole County issuing an invitation for bid on wastewater pump station repair and refurbishment services (due August 5, 2026). The code shows moderate but sustained activity; opportunities posted between late February and mid-July 2026 span federal-grant-funded orphan well programs and routine municipal water infrastructure procurement.
