HydroVolve EvoLOG
Drill-String Dynamics Data Logger
EvoLOG is a drillstring dynamics logging tool which can be deployed in any drilling operation to record the behaviour of the drillstring over a period of time.
EvoLOG continuously logs parameters of Tensile Force, Compressive Force, Torsional Force, Multi-Axis Acceleration, Pressure and Temperature in both bore and annulus at a sample rate of 4000Hz for 160hours. Time delays, and programable intervals and triggering values can be utilised to maximise the effectiveness of the recorded data and to preserve battery life.
EvoLOG is programmed through the windows Graphical User Interface (GUI) with the necessary triggering and data capture parameters for optimal drillstring dynamics recording set prior to deployment. It is recommended for use in fishing operations, casing pulling campaigns, liner and casing deployment, and in slot recovery and side-track operations.
