... Abstract Caprock integrity in steam-assisted gravity drainage (SAGD) has been evaluated by various researchers. However, most of these caprock integrity studies assume that the caprock is not fractured, which is not a valid assumption in most cases. This paper provides a comprehensive analysis...
