Kansas City Company Uses US Product, TerraThane, to Keep Natural Gas Flowing in Nation’s Ninth Largest Gas Reserve
FORT LUPTON, CO—An unfortunate inlet line break at one of Anadarko Petroleum’s hydraulic fracturing stations in Weld County, Colorado just north of Denver, allowed injection fluid to wash out the end of the pumping station and get beneath the concrete slab foundation causing erosion. The voids created beneath the slabs were from three inches to five inches and left the slab floor uneven. The general contractor for the station, Open Range Services, initially thought to use the legacy method of mudjacking, or pressure grouting: pouring a thick grout of mixed concrete and other aggregates into the void, or backfill, but the “mud” is heavy which can affect the surrounding soil, time consuming, and difficult to apply and clean, and backfilling would have required the costly process of ripping out the slab and replacing it. Instead, they contacted Pro Foundation Technology, based in Kansas City, MO, to learn more about a contemporary technology called “foamjacking” or “polyjacking,” which uses lighter weightgeotechnical polyurethane foam instead of grout.
