Acoustic permeability log utilizing differential traveltime measurements
Patent
·
OSTI ID:7179391
Two high-intensity pulsed acoustic (50 to 500 hz) sources, one above the other in a fluid-filled borehole, which are 180/sup 0/ out-of-phase push fluid in and out of the formation near the borehole. The difference of the formation ultrasonic velocities measured with and against the fluid flow is related to the permeability of the formation.
