FWS60: Fullwave Sonic 

The advantage of the FWS60 tool is that it digitises and transmits to the surface the full sonic waveform arriving at each receiver during a user-configurable sampling window. For each receiver the user can choose one of three sampling periods to optimise the acquisition according to the application and/or formation characteristics.

The sonic waveform data provided by the FWS60 has many applications: these include the determination of formation mechanical properties, fracture analysis, permeability and porosity estimation and cement bond assessment.

According to customer preference, the probe can be supplied with three (version 3RX) or four (version 4RX) receivers.
