| Abstract: | This study aims to integrate core and wire line logging data for evaluation of Kareem sandstone (Middle Miocene) in Ashrafi Field, Gulf of Suez, Egypt. The study has been carried out on seven wells ASHRAFI_A_01_ST, ASHRAFI_A_02_ST, ASHRAFI_H_IX_ST2, ASHRAFI_I_1X_ST, ASHRAFI_K_1X, ASHRAFI_SW_04, ASHRAFI_SW_06, by using wire line logging data and core data. The interpretation of these data has been done by using Interactive Petrophysics software.The Net pay thickness ranges between 17?ft to about 110?ft, porosity varies from 13% to 26%, permeability from 125?mD to about 960?mD, water saturation from 19% to about 50% and shale content from about 18% to about 56%. The interpretation of the Kareem sandstone (core data for ASHRAFI_SW_04 well) indicates that the average core porosity value is about 17% and the average core permeability is about 800?mD, which indicate a suitable reservoir. The porosity increases with the increasing of the permeability and the relationship between them has good correlation coefficient of 0.81 for wire line logging data set and 0.85 for core data set. These relations can be used to determine permeability from porosity for sandstone of Kareem Formation.The new development area for Ashrafi Field can be determined where there are two zones: one in the Middle and the other in South west. Stratigraphic correlation chart shows that, the Kareem Formation thickness varies laterally in Ashrafi field so, the new well location could be determined perfectly. The integration between well logging data and core data are very important tools to evaluate the degree of heterogeneity in the Kareem sandstone and storage capacity properties as well as the zone of interest of productivity and perforation. |
