Abstract
A sonic logging tool which includes a relatively short sonic wave isolation section and further includes a structural member surrounding a pressure wave generating apparatus for creating a damping shorted turns effect is disclosed. The isolation section includes interlocking ends having serpentine edges which are spaced from each other, but which are interlocked for preventing longitudinal separation of the two ends. The isolation section also includes a damping material disposed between the spatially separated serpentine edges. The structural portion permits an electrical current to pass therethrough around the pressure wave generator apparatus.
