EM25, Single induction probe. EM25: Single Induction (small diameter) The Slim Single Focused Induction EM25 sonde uses a three-coil focused electromagnetic array to provide a conductivity log . An oscillating high frequency magnetic field from a transmitter coil inside the probe induces an alternating electrical current within the surrounding conductive formation. This current, in turn, induces a voltage within receiver coils in the probe proportional to the formation conductivity. The transmitter-receiver spacings determine the depth of investigation of the measurements. Additional focusing coils minimize the contribution of the borehole signal. The sonde coil spacings are optimized to achieve high vertical resolution and a deep radius of investigation, with minimal borehole influence when logging in conductive-fluid-filled boreholes. The Slim Single Focused Induction EM25 sonde main features are : Formation conductivity measurement in dry or fluid-filled borehole or even in PVC casing Phase detector discriminates between magnetic susceptibility and conductivity signals Natural gamma measurement available for correlation Contact us to get a quote or request more information.

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.

DTN38, Dual Neutron thermal probe, neutron neutron, dual neutron. DTN38: Dual Thermal Neutron The standard DTN38 probe provides long-(LSN) and short-spaced(SSN) 4π thermal neutron measurements. Since the probe reacts strongly to hydrogen content, the principal application of this method is for formation water content (porosity) measurement. As an option (highly recommended), the probe can be supplied with a natural g amma detector to permit the influence of clay content on the results to be evaluated. Useful when the probe is deployed for through-tubing oil/water/air contact measurements, a casing collar locator (CCL) detector is also available as a factory-fitted option for this probe.
