we studied the reservoir parameters of Upper Kangan formation in two wells using core data (including petrography and capillary pressure test). We used 271 and 161 plug samples for permeability, porosity and density measurement in well 1 and 2, respectively. Also we utilized HRLA (High-Resolution Laterlogy Array Tool) and DSI (Dipole Shear Sonic Imager) tools and other conventional wire lines for petrophysical evaluation. For evaluation of pore throats and their distributions and their effect on reservoir characteristics in limestone and dolomitic samples, mercury injection test was performed by Auto Pore mercury injection apparatus. Petrographic studies include definition of porosity types, microfacies, digenetic and dolomitization processes in samples. Acquired results of this study have shown that the upper Kangan indicates poor to fair reservoir quality.
