oa A Model of First-Contact Condensation in a Heavy Oil Reservoir Heated By a Condensable Fluid

Decline in conventional light crudes and current high demand for oil is making exploitation of heavy oil resources an<br>important part of the portfolio of major oil companies. Although the volume of heavy oil resources is vast, of the order<br>of 2.5 - 3 trillion barrels, their development is still very challenging. From a technical perspective, one of the major<br>issues is how to optimally heat the reservoir and thus decrease the high viscosity of the deposits in-situ.
