Abstract :
The hydrodynamic activity and its effects on oil water contact of oil fields in Sirri district ( Eastern Part of the Persian Gulf), has been revealed by drilling and coring of third well of Mishrif reservoir, (SiDA1) on 1976. Discovery of Sirri –D1 ( Dena) in 1972 and SiD-2 confirm existence of oil only 5 meter at the top of structure. Field development started in 1975 and showed the existence of tilted, oil- water contact along fairly south –north direction with slopes up to 12:1000, particulary on the western flank of structure. Slope and direction of water level of Sirri-C ( Sivand) which is close to Sirri-D (Dena) , contain the same slope in both field, at the eastern border of field. The oil –water contact of Sirr- E, (Alvand) field has been constructed with good accuracy and fair probability in 1978. As a result, this modeling was confirm with actual result after full field development of this field on 2002. An entirely original study has been undertaken on residual oil of core, which permitted to characterize various zone as well as modern and fossil interfaces, and proved Hydrodynamic activity in the Mishrif reservoir in western part of Persian Gulf ( Sirri District). This study was carried out, with an approach to combined reservoir characterization , and revealed accuracy of results after full development of these fields.
