In this study, the influence of these parameters upon cumulative production and recovery factor of an Iranian fractured reservoir were studied by the usage of a simulator. Results show that, changing the block heights greatly affect on the cumulative production as well as the recovery factor. Also sensitivity analysis reveals that, the variations in cumulative production and recovery factor happen in a limited range of block heights. The aforementioned ranges of block heights for the studied reservoir were twice the height and one tenth of the height of the block height used in the history matching during the reservoir simulation. For block heights shorter than the original one, the influence of capillary continuity is paramount by increasing the cumulative production as well as the recovery factor. However, as the block height increased and reached twice the height of the original height, the influence of capillary continuity decreased and the system behaved similar to the situation where the block height was doubled without taking capillary continuity into consideration.   %U https://ijcce.ac.ir/article_6843_5328ae0f7068b3493bbd7a242176ef9f.pdf
