Structural-Petrophysical Modeling of the Asmari Reservoir, Ramin Oil Field

Ramin oilfield is located at Dezful Embayment. It consists of Asmari and Bangestsn reservoirs which are in production stage. The present study focused on Asmari reservoir. It was attempted to construct 3D structural- petrophysical models which is important in field development. In this oilfield the Asmari reservoir is divided into 4 zones. Model utilized all available data such as geophysical data, well logs, petrophysical data evaluation, core data, thin sections, and reservoir engineering reports. Reservoir Modeling System (RMS) was implemented using geostatistical method to construct 3D reservoir modeling. This model consists of structural and petrophysical models. Structural output data were applied to create petrophysical model. Modeling steps included of griding, kriging and account experimental variogram for available data. Dimensions of each cell in grid model is 193><228xlm except for zone 4 (nonreservoir) changed to 193x228x5m. Asmari reservoir modeling in Ramin oilfield revealed that zone 1 is the main pay zone and contains about 97.9% of total oil volume in this field.
