Reservoir Engineering

1. Capillary pressure not being uniquely dependent on saturation, how easy would it remain to deduce the data on the saturation history of the core (hysteresis) @ laboratory-scale using experimental investigations?

Feasible to capture the associated oil-water interfacial area @ lab-scale?

How do we go ahead with Euler characteristics using experimental investigations?

2. Why does ‘capillary pressure-saturation relationship’ not uniquely describe drainage and imbibition processes associated with a multi-phase fluid flow through a petroleum reservoir?

How could we ensure that capillary pressure-saturation-interfacial area surfaces would be able to eliminate hysteresis @ core-scale using experimental investigations?

Feasible to capture the interface relaxation that critically influences the formation of interfacial area?
