Heavy oil production with energy effective steam-assisted gravity drainage [PDF]

open access: yes, 2016
In reservoirs with extra heavy oil and bitumen, thermal methods are used to reduce the viscosity, in order to extract the oil. Steam-assisted gravity drainage (SAGD) is a thermal method where continuous steam injection is used.
