  • Method of treating a well using fluoboric acid to clean a propped fracture
    Patent number: 4160483
    Abstract: The permeability of the prop pack in a subterranean fracture containing a propping agent is improved by contacting the propping agent with fluoboric acid. The fluoboric acid slowly forms hydrolysis products, including hydrofluoric acid and hydroxyfluoboric acid, which react with and stabilize clays and other fines in the prop pack, thereby improving its permeability. Because the fluoboric acid hydrolyzes slowly, it can be injected deep into the fracture extremities before significant spending of the acid occurs.
