North American Sites
Sites where FRx has worked in North America
By any metric, FRx has performed an astonishing record of injections, usually by creating hydraulic fractures:

Depth:
Shallowest: 6 inches (just to see if it could be done)
Shallowest remedial application: ~3ft
Deepest remdial application: ~225 ft

Granular material (proppant)
Sand
