Abstract
A sonic well logging tool radially measures circumferential cement conditions longitudinally along a well casing. Sonic signals are transmitted from a plurality of angularly displaced transmitter-transducers, through a borehole fluid, down a longitudinally extending sector of the well casing, and then through the borehole fluid to a plurality of angularly displaced receiver-transducers, which are distally disposed from the transmitter-transducers.
