Abstract
One or more acoustic transducers are used to measure ultrasonic velocities in the mud in the interior channel of a drill collar. Corrections may be applied for temperature and/or fine grain drill cuttings to get the ultrasonic velocity in the annulus between the drill collar and the borehole wall. The latter velocity may be used for caliper measurements and for correcting measurements made by formation evaluation sensors.
