English Abstract

To simulate very large field reservoirs like the ones existing in Saudi Arabia, a large number of grid cells is needed. Pseudo relative permeability curves are used to reduce the dimensionality of reservoir simulation models and to account for intra-cell rock properties variations. Identifying the parameters affecting pseudo relative permeability curves is very important so that the model cells can be grouped in different categories where the proper pseudo relative permeabilities are generated for each group. The objective of this thesis was to identify the factors affective pseudo relative permeability curves. Different reservoir rock and fluid properties were studied. Validation of some curves are also shown. It was concluded that the most pronounced effect on pseudo relative permeability curves is caused by the reservoir dip angle. Layer thickness and PVT properties have also an effect. Production rate and vertical to horizontal permeability ratio have no significant effect on the parameter ranges studied. While absolute permeability for low dip angle cases has no effect, at high dip angle case, absolute permeability effect should be taken into consideration.
