The BDV probe is designed to provide continuous measurement of borehole inclination and azimuth. BDV42: Deviation du Forage The BDV42 probe is used to determine the exact drilled trajectory of a borehole in the subterranean space. Boreholes drilled close to infrastructure such as cables or tunnels can be surveyed before reaching the critical point. Another application of this method lies in water well quality control by ensuring that well deviation and curvature criteria are met so that problems with lowering pumps and other equipment can be avoided. The probe is based on a high-precision c ombination magnetometer and accelerometer sensor providing a continuous measurement of borehole inclination and azimuth. Because of the resulting magnetic disturbance, reliable azimuth data can not be obtained in steel-cased wells or in iron-rich geological formations.

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.

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.

GUIP38, Focused resistivity probe, Guard log. GUIP38: Focused Electric The defining element of the GUIP38 probe, the use of a pair of equipotential “guard” electrodes, ensures a reliable formation resistivity measurement by focussing the injected current in a way that maximises vertical resolution and penetration into the formations while avoiding dissipation in the borehole fluid. As well as providing high-resolution and full-range focussed resistivity measurements, an onboard processor calculates formation conductivity (in mmho/m) and capacitance (µF) values. Due to focussing of the injection current, this method allows a resolution of thinner layers compared to a log of the traditional “normal” type. The othe r advantage of this method lies in the fact that it is suitable for difficult hole conditions (salt mud). This type of log is most often used for formation evaluation (lithology / porosity) and groundwater quality studies. Contact us to get a quote or request more information.
