The DIL38 induction conductivity probe generates an electromagnetic field and provide two simultaneous conductivity logs. DIL38: Double Induction The DIL38 induction conductivity probe generates an electromagnetic field in the vicinity of the borehole and measures the response of the formations to this applied field. On both long (ILD) and medium spacing (ILM) receivers in-phase and quadrature measurements are taken and digitised by the probe electronics for transmission to the surface equipment. In this way both formation conductivity and magnetic susceptibility data can obtained, even in dry or PVC equipped boreholes. The relatively low operating frequency and the design of the coil array combine to minimise borehole effects and maximise both depth of investigation and vertical resolution.

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.

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.

Solution de mesure LIM pour les travaux souterrains UNDERGROUND WORKS The PocketLim is a recorder that monitors drilling parameters during underground work, particularly tunnel boring. Compact in size, it measures depth, advance speed, hydraulic forces, flow rate, pressure, and other parameters in real time, depending on the context. The recorder and its sensors can be easily integrated into any type of underground equipment, including tunnel boring machines. The MiniLIM was recently installed on a latest-generation Robbins tunnel boring machine, the MDM500 Mine Development Machine - Robbins , which is notable for being the first tunnel boring machine with a rectangular cutterhead. The main parameters recorded are: -Instantaneous advance speed -Pressure on the drilling tool -Impact pressure -Rotational torque -Injection pressure and volume Other parameters can be measured on request.

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.
