ABSTRACT:
A process wherein energy generated from a high impulse device is used to jar, loosen, or dislodge scale from a wellbore, downhole production equipment, or near well formation flow channels. Such jarred, loosened, or dislodged scale allows for increased amounts of scale-forming ions to be removed. Alterwards, an emulsified liquid membrane system containing surfactants therein sufficient to remove scale-forming ions is placed in said wellbore. Said emulsified membrane system is removed when the scale-forming ions have been absorbed therein.
