The GR38 measure the relative naturally occurring radiation adjacent to the well hole providing well-run correlation and lithological identification. GR38 & GR25: Natural Gamma Radioactivity In addition to its primary role as a lithological or clay indicator , a Natural Gamma measurement is frequently used as the basis for establishing correlations between boreholes and to ensure accurate depth matching between different logging runs made in the same borehole. For these reasons, many LIM LOGGING probes provide this measurement as an additional log along with other parameters. The GR38 & GR25 probes provide a solution for cases where only a basic, total counts natural gamma log is required. Based on a ø25 x 50 mm NaI(Tl) and ø12.7 x 50 mm NaI(Tl) scintillation crystal detectors coupled to a high-performance photomultiplier tube, the probes boast excellent sensitivity (±1.2 cps / API unit) and provide a high quality final result.

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.

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.
