Zusammenfassung:	The present invention relates to a method for determining hydrocarbon production for a reservoir. The method comprisesdetermining a projector matrix based on a Jacobian matrix function of the gridded model, then splitting the Jacobian matrix into subsets of consecutive lines.For each subset of consecutive lines, creating a respective square matrix based on said subset.A determining eigenvectors and respective eigenvalues associated with the respective square matrix and then determining relevant eigenvectors having respective eigenvalues below a predetermined threshold.The projector is determined as a concatenation of the extended eigenvectors ordered according to multiple criteria: the respective order value of the subset; and the respective eigenvalue of the relevant eigenvector.
