In this study the effect of different petrophysical parameters on the velocity of compressional waves has been studied. A coloumn of 70 m height has been selected from the Asmari formation in one of Iranian oil reservoirs. The petrophysical parameters were determined for 150 plug samples. The well logs obtained for desired depths were evaluated and corrected to obtain a correlation between the petrophysical properties and the velocities. The data from petrophysical expriments and well logs were matched.
The results show a scattered linear relation between the velocity of compressional waves and porosity values, but the variation of velocity has been formulated as a function of porosity and density. The effect of depth, density, and absolute permeability has also been analyzed.
