The PressioLIM is a Pressure Volume Controller (CPV) that enables a pressuremeter test to be carried out in manual mode. PressioLIM The PressioLIM is a Pressure Volume Controller (PVC) that performs in situ pressuremeter tests in manual mode (adjustement of pressure levels by the operator). It can be used with or without data recorder. The PressioLIM meets the EN-ISO 22476-4 European standard (L. Menard). Two versions are available: ✓ The PressioLIM 50 , 0-50 bar (calibrated up to 80 bar). ✓ The PressioLIM 130 , 0-130 bar for High Pressure in situ pressuremeter tests. For the in situ pressuremeter tests acquisition, the PressioLIM is compatible with PocketLIM , MiniLIM and NanoLIM data recorders. Contact us to receive a quote or request further information.

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.

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.

The BHTV42 sends highly focussed ultrasonic pulse radially outwards towards the borehole wall up to 360 times. Acoustic borehole imager. BHTV 42: Televiewer Acoustic Wall Imaging. The BHTV42 acoustic televiewer tool employ a rotating transducer mounted at the lower extremity of the tool to send a highly focussed ultrasonic pulse radially outwards towards the borehole wall up to 360 times per revolution, the amplitude and travel time of which are measured on its return to the probe after reflection at the borehole wall. This information, combined with the data given by the tool’s onboard orientation system, provides an extremely detailed and orientated acoustic image of the borehole wall.
