摘要

Three-dimensional numerical earth models play an increasingly central role in the engineering and petroleum industry. They are routinely used to plan new wells calculate hydrocarbon reserves and when coupled to flow simulator, predict production profile. In the reservoir modeling subject there are different methods for 3D-static modeling of these methods in the present study the geostatistical method is used for 3D-static model of lower shuaiba in the West of Persian gulf. This paper focus on constructing static model for Lower Shuaiba formation is discussed and the 3D static model and property maps showing the oil reserves are presented. Oil in place estimate based on volumetric calculation is finally provided. The static model of Lower Shuaiba formation in the west of Persian Gulf revealed that the major oil deposits lie in the F3 area with some minor deposits in F1, F5 and F8 areas. The oil in place from F3 area amounts to 359.1 MMSTB and from F1, F5 and F8 area are estimated to be around 28.6, 29.9 and 27.9 MMSTB, respectively. Considering the cumulative oil production from Lower Shuaiba being 13.6 MMSTB, 431.9 MMSTB of oil is remaining to be exploited. With a recovery factor of 10% with natural depletion (being on optimistic side) the Lower Shuaiba oil reserve is estimated to be around 31 MMSTB.
