Abstract: A method is provided for removal of barium sulfate scale from oil and gas bearing equipment. The method includes the steps of creating an alkaline condition within the equipment; adding to the equipment one or more accelerants; reacting the accelerants with a surface of the barium sulfate scale, to etch the surface and form one or more nucleation sites; attaching molecules of the accelerant to the cations of the barium sulfate scale; adding to the equipment one or more chelants; and reacting the chelants with one or more of the nucleation sites of the barium sulfate scale, the reaction leading to occupation of reaction sites on the surface of the barium sulfate, complexation and dissolution of the barium sulfate. The accelerants have smaller molecular size than a molecular size of chelants to adsorb onto barium sulfate crystals that are otherwise unreachable by the larger chelant molecules.
