WebSonic logging is a well logging tool that provides a formation’s interval transit time, designated as , which is a measure of a how fast elastic seismic compressional and shear … WebA sonic transmitter and receiver are employed to locate and evaluate zones of significant porosity in the proximity of a borehole. Continuous wave and pulse techniques are used to locate the zones and to determine the void dimensions by means of frequency domain signatures. Both through-transmission and reflection methods are employed.
WebThe full waveforms recorded by an array of receivers in a modern borehole sonic tool contain secondary arrivals that are reflected from near-borehole structural features. These arrivals are used to form an image of the near-borehole structural features in a manner similar to seismic migration. Possible uses of this technique include horizontal ... WebDec 4, 2024 · Borehole Compensated Sonic Logs. Borehole compensated sonic logs have two sets of transmitters and receivers, which measure compressional waves and average the travel time . This type of log automatically compensates for variations in the borehole diameter or size and sonde tilt, as well as, increases resolution from 2 feet to 9 inches.
