... Where C is a constant and S w * is the normalized wetting phase saturation. S w * is expressed as: (3) S w * = S w − S wi 1 − S wi . Thomeer (1960) proposed an empirical relationship between capillary pressure and mercury...

... Abstract Determining the capillary pressure behavior of rocks at reservoir temperature and pressure is vital in understanding the displacement mechanism in the reservoir. An understanding of the displacement mechanism is essential to evaluate its effect on fluid saturations and oil recovery...

... Abstract Engineers involved in numerical reservoir simulation studies typically use capillary pressure for model initialization. However, the effects of capillary pressure on reservoir performance may not be fully understood for different drive mechanisms. The aim of this work is to show...

... gradient, psia/ft θ =dip angle, degrees Recalling the concept of capillary pressure we have (3) p c = p o − p w where p c = capillary pressure, psia Replacing water pressure in Eq. 2 by Eq. 3 , we have (4) q w = k k rw μ w...

.... The pore spaces control the amount of porosity, while the pore throats control the movement of fluids and the quantity of rock permeability. The core analysis data for 219 sandstone and limestone samples were available. The data include porosity, permeability and capillary pressure by mercury injection...

... drainage curve where the non-wetting phase, oil, pushes the wetting phase, water, out of the pores due to gravity differentiation. The capillary pressure goes to positive infinity as water saturation approaches irreducible water saturation. Primary imbibition curve is used to imitate the water flooding...
