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.

ABOUT Since 1985 LIM has been recognized internationally as a specialist in instrumentation and measurement, whether during or after drilling (drilling instrumentation and borehole logging). From the beginning, technological innovation has been an integral part of the LIM group's DNA. In terms of INSTRUMENTATION which is its core historical business, LIM SAS offers a wide range of data loggers whether for drilling parameters, in-situ geotechnical tests (Pressuremeter, Penetration tests, Lugeon packer tests) and special foundations processes such as low pressure grouting, jet grouting, bored piles, ... LIM SAS recently completed its range of data loggers with equipment allowing borehole deviation measurement and high precision GPS navigation (RTK) for drilling rigs. Thanks to its GEO-LOG 4 cloud based sofware, LIM offers a solution that automatically transfers and preprocesses data recorded on site. In terms of geophysical BOREHOLE LOGGING, LIM LOGGING , which is the result of the acquisition by LIM of Electromind in 2017, now offers a very complete range of logging probes. At the international reputation level, the OPTV and BHTV televiewers from LIM LOGGING are unanimously considered to be the benchmark products on the market. 1985 Year of creation > 150 Countries > 5 000 Number of equipment sold CUSTOMERS And many others !

The TC25 probe is a small-diameter logging probe for measuring temperature and conductivity. TC25: Temperature & Conductivity The TC25 probe, based on a sensor assembly incorporating a precision 7-ring conductivity cell and a sensitive thermistor, provides fluid temperature and conductivity measurements in a slimline format. It is primarily intended for groundwater monitoring, such as in piezometer tubes and other PVC or steel-cased boreholes. Contact us to get a quote or request more information.

PDS, Probe Deployment System, Borehole logging horizontal boreholes, Borehole logging upward boreholes. PDS: Probe Deployment System The PDS allows OPTV and BHTV imaging probes and certain other types of probe to be deployed in steeply inclined, horizontal or up-holes, where assistance from a drilling machine is required. It has been successfully used in boreholes exceeding 400 m in length. The main housing containing the probe is manufactured from aluminium and the standard kit includes 2 x 2 m aluminium rods to allow imaging probes to operate in non magnetically disturbed conditions. A variety of nose cones, adapted to different types of probe, and housing centraliser blades for boreholes of up to 150 mm diameter can be supplied. Behind the housing the logging cable runs along the outside of the drill rods (AQ or BQ recommended). The drill rod adapter incorporates a centraliser to support the weight of the drill string. A precise depth measurement is obtained using the lateral movement of the drilling machine’s drive head. Contact us to get a quote or request more information.

IP38, the formations surrounding the borehole are subjected to an alternative square-wave voltage applied via the upper and lower injection electrodes. IP38: Induced Polarisation The formations surrounding the borehole are subjected to an alternative square-wave voltage applied via the upper and lower injection electrodes. Following each injection cycle, the resulting potential difference over a section of the formations is analysed as it decreases with time. The form of this decreases curve is related to the chargeability of the formations. A high chargeability indicates that induced electrochemical potentials are able to develop within the formations as a result of ion transfer between pore fluids and semi-conductive metallic mineral grains present within the rocks. The IP38 probe is particularly suitable for mining exploration in the context of a disseminated sulphide mineralisation. In the hydrogeological domain, it can also provide qualitative information about the permeability of potential aquifer horizons. Contact us to get a quote or request more information.
