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.

The FTC60 probe provides precise readings of the flow speed of the fluid, the temperature and the electrical conductivity contained in the borehole. FTC60: Temperature/Conductivity/Flow The FTC60 probe provides precise readings of the temperature, electrical conductivity and flow speed of the fluid contained in the borehole. Its main applications are in obtaining groundwater quality and production data in hydrogeological or pollution studies , either on a single or multi-well regional basis. Another possible application is the detection of setting cement by means of the heat given off during this process; for example in a borehole after casing installation and grouting or in quality control of cement piling works. The lightweight impeller and low friction bearing assembly permit this probe to react almost instantly to any vertical movement within the fluid column of a well or borehole.
