The device is multi-frequency
Features and benefits
- The device is integrated with existing MWD systems LHE630N and LHE650N
- Symmetrical design of the probe part compensates for the drift of the receivers and reduces the influence of borehole effects
- The double probe part of the design – prevents the effect of eccentricity of the tool and dielectric effect
- Measurement at two frequencies, 2 MHz and 400 kHz
- 8 log curves of electrical resistivity.
- The presence of azimuthal gamma-ray logging (optional).
- The device is powered by standard lithium batteries.
