The RG micro resistivity imaging probe provides a high-resolution spacially oriented image of features on the borehole walls.
The tool includes 4 pads each containing twelve button electrodes mounted on 2 pairs of powered arms.
microresisitvityThe current emitted by each electrode is focussed into a narrow beam and returns to a remote part of the tool body. The current from each electrode is measured and digitised in each pad and transmitted to the surface by a separate telemetry module using a proprietary high-speed communications system.
The tool may be run on standard 4-core or 7-core cables and is compatible with the standard RG oilfield surface system running Warrior software.
