Basic Research

 

Trying to understand the behavior of fluid flow in a fractured reservoir as against the conventional classical porous medium, where we do a have reasonable understanding in describing fluid flow, especially at the macroscopic scale. However, in a fractured/carbonate reservoirs, it is extremely difficult to deduce a reasonable REV, which in turn, poses a great challenge in deducing the mean value of the dependent variable of interest (spatial and temporal distribution of pressure and saturation profiles). In this context, investigations are being carried out in order to capture the anomalies associated with a fractured/carbonate reservoirs with reference to the single continuum hypothesis of a classical porous medium.
