Abstract
At least two samples of a porous medium with different lengths are exposed to acoustic waves emitted by a source. For each sample, acoustic wave arrival times are registered at a receiver and acoustic propagation velocity in the porous medium is determined by analyzing changes in the arrival times relative to changes in the lengths of the samples.

A method for determining acoustic velocity in a porous medium, the method comprising:
- exposing at least two samples of a porous medium having different lengths to acoustic waves emitted by a source;
- for each sample, registering acoustic wave arrival times at a receiver for the acoustic waves emitted by the source;
- and
- determining acoustic propagation velocity in the porous medium by analyzing changes in the acoustic wave arrival times relative to changes in the lengths of the samples.
