Abstract
ABSTRACT
The effectiveness of vertical and horizontal wells in combination for recovery of viscous oil is increased by injecting a mobility control agent into the horizontal well after breakthrough of a thermal fluid from a vertical well down to the horizontal well. The area for gravity drainage of oil into the horizontal well is increased, resulting in greater recovery of oil from the horizontal well.
