Abstract
A method and apparatus for inter-well seismic logging include a seismic source capable of being lowered into a first or surce well and a plurality of receiving and/or detecting means capable of being lowered to at least one second or receiving well. Signals generated from the seismic source pass through the earth and are received by the respective receivers. The recorded data is subsequently computer processed to form a profile which represents the geological configuration between the wells. The seismic source having at least one bender arm assembly including two sets of piezoelectric ceramic crystals and, preferably, a reaction mass connected intermediate the ends thereafter generate the seismic signals.
