Treatment of relative permeabilities for application in hydrocarbon reservoir simulation model

Measurements of relative permeabilities and their analysis and modification by means of appropriate relative permeability models represent one of the bases for development and verification of reservoir simulation models. It requires careful selection of these curves providing that a statistically sufficiently relevant groups of similar curves are available for the selected reservoir or for individual rock types within the same reservoir. In order to be able to correctly apply these curves in reservoir simulations, previous knowledge of all reservoir rock parameters is required, i.e. porosity, absolute and effective permeability, saturation, etc. Objective of the paper is to present procedures of relative permeability curve measurements and analysis methods of data experimentally obtained from different models which describe such data, to be able to apply them with high degree of quality in numerical reservoir simulations. In that regard, the final part of the paper through a concrete example shows the procedure of relative permeability data analysis and their processing for application in hydrocarbon reservoir model construction.
