Heavy Oil - Timelapse Fluid Influences and Mapping

Understanding the sensitivities of temperature, pressure and saturation changes to the rock properties is key to allowing us to identify changes in the 3D/4D environment. Here we review the magitude of the different influences and show how we can map the summation of these influences in the subsurface. Once we have done this we can highlight remaining areas of un-affected reservoir. This paper is the first of two which highlights the changes within a Steam Assited Gravity Driven (SAGD) environment.
