Uniqueness Conditions in a Hyperbolic Model for Oil Recovery by Steam Drive

The speaker will present a simplified model for oil recovery by steam drive. The model assumes the existence of a Steam Condensation Front (SCF) which propagates at a speed determined from a local energy balance and that capillary forces are absent. The resulting hyperbolic transport equations for the phases, oil, water, and steam, can only be solved when matching conditions across the SCF are known. The speaker will demonstrate explicitly how to obtain such conditions and show how different transition models yield different matching conditions. In particular, he will discuss the influence of the local temperature and steam behaviour, as well as the form of the capillary forces in the transition model.
