Description
The large diameter RADii® HD Segmented Cement Bond Tool uses a single ceramic transmitter, a sixteen segment receiver at 3 ft. and a single receiver at 5 ft. spacing. The segmented receiver generates a cement map which enables identification of cement channeling while the single receiver generates the traditional cement bond log (CBL) and a variable-density log (VDL).
