Abstract

The effect of fluid content to the sonic wave propagation in the reservoir rock has
been studied experimentally using the well log data. Evidence shows that the water content
affects the sonic wave propagation only in a specific interval, while oil content also affects
the sonic wave propagation but at a specific low interval. There is a discontinuity where
the effect of oil content changes suddenly with an increasing oil content. Higher than this
value it seems that there is no effect of oil content on sonic wave transit time.
