Sondex’s TRIM Induction Resistivity Tool to Enable Real-time Formation Evaluation

The TRIM Resistivity Tool induces a 20 Khz magnetic field into the formation, which generates eddy currents proportional to its conductivity. These currents are measured by the TRIM sensor package, which is mounted in a side channel in the resistivity sub, providing superior protection against borehole wall impact damage and allowing easy maintenance and replacement when required.

Typically situated at the bottom of the LWD string, the tool transmits data in real time for correlation and geosteering purposes. Calibration is straightforward with sonde error and temperature corrections applied downhole in firmware. Deconvolution, borehole corrections, etc, are automatically applied by the Geolink Navigator surface software.

Features:
Wireline comparable log – 20 Khz frequency.
Straightforward calibration – sonde and borehole corrections in software.
Side channel mounting – sensor protection and easy maintenance.
Depth of Investigation – equivalent to wireline deep induction.
Good vertical resolution – equivalent to wireline medium induction.
