Resistivity Temperature Induction Gamma Natural HRTIG-453
W&R downhole tool HRTIG-453 is designed for measurement of electric conductivity, resistivity and gamma natural activity of rock profile in boreholes, borehole fluid temperature.
High stability and exceptionally wide dynamic range are giving you possibility to carry on precise measurements of conductivity of sand-clay layers and also mineralised watersoaked sand beds.
The probe is constructed to be suitable for wireline survey in water filled or dry borehols completed by openhole or plastic casing. The response of the tools is practically instantaneous (<0.5s).
