Abstract
Steam assisted gravity drainage (SAGD) equipment including steam generating equipment may be cleaned using supercritical carbon dioxide. Supercritical carbon dioxide is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure. Supercritical carbon dioxide has exceptional solvent qualities that can dissolve, soften, or dislodge the refractory fouling deposits in the SAGD equipment.
