EXPRESS STACK SONIC
TOOL - 4323

The Full Wave Sonic tool contains a single transmitter and three receivers to record formation travel times. The full wave form data is also recorded simultaneously, along with near, mid, and far travel times, borehole-compensated delta time, calculated sonic porosity, receiver gains, near/far amplitudes and natural gamma. The sonic or acoustic log uses the basic principle of sound waves traveling through a media. The Century sonic system uses a single transmitter and receiver system for recording the travel times of the formation. The receivers are spaced  approximately 3, 4, and 5 feet,  from the transmitter. Therefore, a 0.3 m (1 ft.) calculation can be made to measure this interval transit time.
