... a challenge due to free gas formation upon heating. To establish equilibrium and due to local pressure gradients, this gas is pushed to the edges of the steam chamber, where temperatures are lower. The gas acts as a thermal insulator, reducing the efficiency of heat transfer between the steam and bitumen...
