Full Wave Sonic Tool 2009 All Rights Reserved-Century Wireline Services
The Full Wave Sonic tool contains a single transmitter and dual receiver to record formation travel times. The full wave form data is also recorded simultaneously, along with near 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 dual receiver system for recording the travel times of the formation. The receivers are spaced  approximately 2 and 3 feet,  from the transmitter. Therefore, a 0.3 m (1 ft.) calculation can be made to measure this interval transit time.  Additionally, the 9320 can be upgraded for cement bond logging, by adding a casing collar locator (see below for link).
