Upgridding the geological model to reduce the number of grid blocks while maintaining the essential heterogeneity details to preserve the dynamic performance is the only solution to this problem...

... and efficient algorithm for rigorous flash forms the basis of the whole strategy. Secondly, a tie-line distance based approximation (TDBA) method has been introduced on top of the rigorous algorithm. In the TDBA method, if a new feed composition in a grid block is close enough to a tie-line previously...
