ABI43-ICDP (Logging tool)


Model id: QL43-ABI: acoustic televiewer cartridge 2nd generation, ALT 18581

Measurements:

  • travel time of an acoustic signal
  • amplitude of an acoustic signal
  • probe orientation derived from magnetometer and accelerometer/gravimeter data
  • magnetic field amplitude

Purpose: geological structures: bedding, foliation, lamination, natural & induced fractures, breakouts, high-resolution oriented borehole calliper, borehole trajectory, casing inspection

Characteristics: sonic frequency: 1.2 MHz; up tp 20 rev/s; azimuthal resolution: 72, 144 or 288; caliper resolution: 0.08 mm; Vertical resolution [m]: images: 0.005, orientation: 2, mag-field:0.1

Limitations: The probe does not work in extremely soft formations, e.g. almost unconsolidated lake sediments; requires centralizers with diameter of 60 mm
