Kumar, Munish; Sok, Robert; Knackstedt, Mark; Latham, Shane; Senden, Timothy; Sheppard, Adrian; Varslot, Trond; Arns, Christoph


Complexities in pore scale structure, rock-fluid and fluid-fluid interactions have a profound effect on the estimation of reserves, recovery and productivity in reservoir rocks. These complexities determine the pore scale distribution of fluids within the pore space. An example is the estimation of water saturation via resistivity measurements. Default saturation exponents (n=2) are often used in estimating saturations despite experimental laboratory results which show a wide range; 0.9<n<6....[Show more]
