Abstract: A geomechanical probe for a drilling well comprises a logging box located between two inflatable preventers and including a plurality of tracers movable radially and urged outwards by springs for engaging the well wall. The tracers are mounted on pistons which are received in cylinders and urged radially inwards by springs for retracting the tracers, the pistons being driven outwardly to displace the tracers into working positions abutting the well wall by supply of actuating fluid to the cylinders. The position of the tracers is determined by differential transformers having cores fixed for radial movement with respective tracers. The preventers are inflated with pressurized fluid which is supplied thereto along passages in the probe which also supply pressurized fluid to the well space between the preventers to act upon the well wall.
