porosity modeling of kushk reservoir in an oilfield located in abadan plain using electrofacies

The 3d effective porosity modeling of kushk reservoir in an iranian oil field is the main topic of this paper. for this purpose, the electrofacies analysis was used for better porosity distribution in gadvan formation. for electrofacies analysis some logs including effective porosity, calcite, sandstone, and shale volumes have been used as input data. the applied algorithm for clustering is multi-resolution graph-based clustering (mrgc). based on this analysis, six electrofacies have been detedcted. two sandy facies possess high porosity, whereas, two shaly facies show improper reservoir characteristics. in this paper, data analysis of porosity has been linked to all facies codes in order to achieve a great match between porosity distribution and relevant facies code. the porosity map of kushk reservoir of gadvan formation shows increasing effective porosity toward the northern sections of the studied area.
