Wettability Measurement @ Laboratory-Scale: Replicating Real-Field scenario: Feasible?
When ‘changes in wettability’ (in a real-field) have been shown to affect capillary pressure, relative permeability, irreducible water saturation, residual oil saturation, electrical properties; secondary (water-flood behavior) and tertiary oil recovery.
If so,
whether the laboratory-scale wettability measurements can be carried out with all the above (actually) associated reservoir–physics – during the wettability measurements?
Else
In the absence of these associated actual reservoir-physics during the wettability measurement at the laboratory-scale, whether, the wettability of the used core at the laboratory-scale can afford to remain to be the same as that of the wettability of the undisturbed reservoir rock?
Lab-scale measurements ( especially the ones that has been performed with in-situ taken samples) gives you an idea regarding the wettability profile of your reservoir. And the accuracy increases in a direct proportion with the number of your samples. However, I always choose to assist my lab findings with other methods (logs etc...)
