Description
The capillary pressure defines the difference in pressure
between the non-wetting and wetting fluids. The capillary
pressure is part of the flow governing equations and its
definition can have a profound impact on the nature
of fluids displacement in a multiphase flow environment.
Conventionally, the capillary pressure - saturation relationships
are determined under equilibrium conditions which signify that
all the fluid-fluid interfaces that exist at the pore-scale maintain
a static configuration at a certain instant in time. However,
there exist experimental and numerical evidences that state
that the dynamic nature of fluid flows indeed play a prominent
role in defining the trends of the capillary pressure - saturation
relationships. In this work we develop a first of a kind semianalytical
model to predict the capillary pressure - water
saturation curves during piston-like drainage displacement by
integrating the dynamics of fluid flow based on fundamental
laws of fluid mechanics.
The proposed semi-analytical model can potentially be
incorporated into existing multiphase flow
simulators to rapidly compute the capillary pressure at various
saturations of the flow medium under dynamic flow conditions.
The presented semi-analytical model has been validated
against experimental and numerical data sets available in
literature at various flow conditions and considering different
sets of fluid properties. We noticed a satisfactory match of the
results predicted by the proposed semi-analytical model
against the literature data. After performing a holistic
sensitivity analysis, we notice that the properties of the porous
medium, fluids and the fluid-solid interactions play a significant
role in defining the trends of the capillary pressure - saturation
curves.
