ABSTRACT:
A time measuring system is provided which automatically compensates for the propagation time of electrical pulses and sonic waves through the apparatus associated with a core analysis system. In this manner, the time required for a sonic pulse to propagate through a core sample is measured exactly and the velocity of the sonic wave through the core sample is calculated based on the propagation time and the sample length.
