SPAK-6D Downhole sonic log tool

The equipment was development by AO NPP VNIIGIS in cooperation with OOO NPC ECO-Technology Foundation

is designed for investigation of cased- and open-hole sections by kinematic and dynamic parameters of compressional, shear and Lamb-Stonely waves.

effective arrival segregation for different waves propagating in a borehole;
improved accuracy of kinematic and dynamic parameter determination of compressional, shear and Lamb-Stonely waves;
tool conveyance to the investigation interval through the drill pipe (inner diameter 90 mm);
fast tool demounting for easy transportation.
