FWS60 / FWS60G

The advantage of the FWS 60 tool is that it digitises and transmits to the surface the full sonic waveform arriving at each receiver during a userconfigurable sampling window. With the option to select both the sampling rate and length of each stage, delayed arrivals such as Stoneley can be acquired without losing vital detail over the earlier part of the acquisition window. The sonic wavetrain data provided by the FWS 60 has many applications : such as the determination of formation mechanical properties, fracture analysis, cement bond assessment and permeability estimation.

We can propose the probe with two (2RX), three (3RX) or four (4RX) receivers.

In option, you can add a gamma ray sensor.
