Abstract
Primary heavy oil recovery relies on the Solution Gas Drive mechanism, which has been the object of many recent research efforts. Current models are unreliable, and it is likely that they do not represent important physical effects. Here, we introduce a Darcy scale model in which the relative permeability of the gas phase is replaced by a new expression for the gas phase velocity based on the relative strength of viscous, gravity and capillary effects.
