Text of Note

A rock type is a very essential tool in characterizing carbonate reservoirs. It is defined as a set of petrophysical characteristics that several reservoir rocks have in common and this is due to the fact that they went through similar diagenetic processes. These characteristics are mainly related to fluids flow and fluid storage capacity, in other words, it will be related to porosity and permeability of the rock sample. Knowledge of different rock types of a carbonate reservoir and their impact on the petrophysical properties and the special core analysis data are a key factor for determining fluids saturations distribution, fluids mobility and recovery factor. The fluids saturation distribution and flow behavior as a function of height in the transition zones (TZ) is often very complex in carbonate reservoirs where these reservoirs are typically characterized with low permeability values. It is believed that variation in oil recovery and residual oil saturations from oil reservoirs are mainly controlled by factors related to the relative permeability of existing and flowing fluids in the reservoir. Relative permeability (Kr) is a critical parameter to evaluate the reservoir performance and when combined with capillary pressure is considered a key factor in defining saturation distributions above Free Water Level (FWL). The impact of different reservoir rock properties such as pore geometry, wettability, fluids saturations, and reservoir temperatures on relative permeability has been investigated thoroughly. As a result of the depletion process occurs in the reservoir, the effective stresses increases and consequently, several petrophysical parameters such as porosity, permeability, pore geometry, and pore throats may alter significantly. Limited studies were performed on the effect of reservoir depletion on relative permeability and residual saturations for carbonate reservoir in the Gulf Region.
