steam-assisted gravity drainageA process used to recover butimen that is too deep to mine. A pair of horizontal wells is drilled from a central well pad. In a plant nearby, steam generators heat water and transform it into steam. [..]

steam-assisted gravity drainagePairs of horizontal wells (an upper well and a lower well) are drilled into an oil sands formation and steam is injected continuously into the upper well. As the steam heats the oil sands formation, t [..]
