4AC 4AC60 : Four-arm caliper probe The 4AC60 borehole geometry probe incorporates two pairs of caliper arms giving independent, perpendicular X-Y diameter measurements, while a magnetometer/accelerometer orientation system provides the borehole azimuth, inclination and X-Y arm directions. In a non-circular borehole, because of differing spring tensions in the two pairs of arms, the tool will rotate in the borehole until the X-Y directions coincide with the maximum and minimum diameter axes. Where a borehole becomes ovalised or develops breakout-type features, it can provide information on stress magnitudes and directions within the geological formations. As an option, the probe can be supplied with a natural gamma detector to provide additional lithological information or for horizon correlation purposes.

PDGC50, Photo-Electric density probe. PDGC50: Photo-Electric Density PDGC50 provides a classic triple-spacing sidewall focussed formation density measurement, with the additional advantage of a incorporating a photo-electric effect energy detection window on the medium-spacing detector. The photoelectric effect (Pe) measurement is a reliable indication of the apparent formation atomic number, meaning that formation lithology and an accurate porosity can often be deduced directly from the results given by the probe. When the Pe log results are combined with those obtained from other probes (eg. spectral gamma) a considerable number of specific « heavy » minerals can be identified. A gamma ray source (Cs137, typically 3.7 GBq), is fixed to the lower extremity of the probe during logging. The source capsule itself is supplied separately by a specialist partner. The mechanical side-walling arm provides a caliper measurement, useful for diameter correction purposes and mud-cake evaluation, and a natural gamma log is a lso obtained by means of a scintillation detector located in the uppermost part of the probe body.

The GYR38 is a gyroscopic bore deviation sensor specifically designed for demanding drilling and mining environments. GYR38 Gyroscopic Probe – Borehole Deviation Measurement GYR38 Gyroscopic Probe – Borehole Deviation Measurement A gyroscopic probe (or gyroscope) is a sensor that measures the rotational velocity of an object around an axis. It allows determining the orientation and angular movements of an object in space. These sensors are used in many applications, ranging from smartphones to ship stabilization systems. The GYR38 is a gyroscopic borehole deviation probe specifically designed for the demanding environments of drilling and mining operations. This north-seeking device (for probe inclination values between 3° and 177° from vertical) accurately provides continuous trajectory data in non-vertical boreholes. A north search time of only 2 minutes and a 60-minute measurement time between corrections help maximize operational efficiency. The GYR38 probe operates in wired mode via our proven eMindLogger acquisition unit. The borehole azimuth and inclination from the IMU are displayed in real time at the surface in our standard 6CH logging software. Additionally, optional parameters such as natural gamma and/or a CCL (Casing Collar Locator) detector can be added to the base probe. Contact us today to request a quote or for more information.
