Full Waveform Sonic

Sonic logs are widely used to provide formation P-wave velocity and mechanical properties. Under suitable conditions also S-wave and Stoneleys wave arrivals can be detected. The Sonic tool is FWS50 by ALT with 4 receivers. https://www.alt.lu/pdf/QL40FWS.pdf

Reflex EZ-Gyro

Minimise the risk of human error

The simplicity of the REFLEX EZ-GYRO™ significantly reduces errors related to data processing and interpretation.

Ensure accurate results

With vertical and angled orientation, fast and accurate orientation of bottom hole assemblies are possible without the need for costly non-magnetic alloys or the risk of magnetic interference.
