Rock physics has been more applicable in petroleum engineering sciences during the recent years. Mathematical and laboratory correlations are developed and play very important role in decision making during exploration and production. Rock physics analysis are crucial in geophysical reservoir characterization which can be compared by processing step in seismic analysis steps. It is obvious that inappropriate proccessing flow produce inefficient seismic results.
In reservoir characterization topic, rock physics stand as a bridge between elastic and petrophysical properties of reservoir.
This report analyzes the modelling procedure of fluid saturations phases in reservoir via reservoir dynamic simulation according to seismic data and relevant attributes. To carry out this, first the data are structurally interpreted and the structural model based on interpreted horizons and faults are prepared. Then the available seismic data are inversed based on the basic model and elastic parameters such as velocity and acoustic impedance of the reservoir are calculated along seismic sections. After seismic interpretation of available data in the studied field, elastic properties of the reservoir are presented via inversion on the basis of resulted model. Acoustic impedance and other seismic attributes are calculated through modeling of some seismic attributes and petrophysical properties of reservoir such as porosity.
