... if observed. The transition zone consists of connate water and mobile water S wm . The equilibrium between capillary and gravity forces controls the mobile saturation, which is thus a function of the capillary pressure p c : (6) p c = p o − p w = Δ ρ g h = 2 σ cos θ...

... defined as "transition zone". It was found that it is the transition zone that hidden the changes of the reservoir properties of both rock and fluids and this is where non-linear transient pressure exists, which has no analytical solutions.

.... The residual oil zone (ROZ) profile at the Wasson Denver Unit is often referred to as a transition zone (TZ) because of the relatively uniform gradational nature of the water (or oil) saturation profile, (shown previously as Figure 1 ). However, the zone is 300 feet thick on the southwest side which clearly...

Abstract Formation water sampling is important for understanding corrosion and scaling potential of the water, characterizing hydrocarbon/water transition zones, determining compatibility between injection water and formation water, and determining optimal salinity and pH windows for polymer...
