The device is multi-frequency EMK LHE873501

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 power can be from a lithium battery and a downhole generator.
