Ronnie L Thomas, Curtis L Boney: Fracturing with multiple fluids to improve fracture conductivity. Dowell Schlumberger Incorporated, Stephen A Littlefield, August 6, 1991: US05036919 (22 worldwide citation)

Conductivity damage is decreased in fracturing a high temperature (greater than 200.degree. F.) well by employing a first fracturing fluid which is substantially stable at the bottom hole static temperature and pumping a second fracturing fluid behind the first fracturing fluid which is less stable ...

Ronnie L Thomas, Frederick A Suhy: Method of treating a well using fluoboric acid to clean a propped fracture. The Dow Chemical Company, G H Korfhage, July 10, 1979: US04160483 (17 worldwide citation)

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 ...

Ronnie L Thomas: Method for acidizing a subterranean formation. The Dow Chemical Company, May 1, 1979: US04151879 (9 worldwide citation)

The permeability of a subterranean formation is increased by injecting into the formation, a conventional mud acidizing solution (HCl/HF) followed by a fluoboric acid solution. Use of fluoboric acid as an overflush is believed to deter clay migration and thereby significantly reduce or delay product ...

Ronnie L Thomas: Method for acidizing a subterranean formation. The Dow Chemical Company, May 1, 1979: US04151878 (8 worldwide citation)

The permeability of a siliceous formation is increased by injecting in sequence, a fluoboric acid solution followed by a mud acid (HCl/HF) solution. The method is particularly advantageous in formations which have a tendency to plug initially upon contact with mud acid, or with HCl commonly used as ...
