Abstract
A method of constructing a reservoir flow model from capillary pressure curves (Pc) and/or relative permeability curves (Kr) is disclosed having application to petroleum reservoir development, acid gas storage and underground water management. After discretizing the reservoir into a set of cells, a principal component analysis is performed for a data table constructed from curves (Pc, Kr) so as to extract principal factors explaining the data. The curves are represented in a representation space constructed from these principal factors and the curves represented in the representation space are classified. At least one curve representative of each class resulting from this classification is then defined and associated with each cell.
