The disclosure relates to a carriage apparatus for carrying a tool string down a wellbore in a wireline logging, and an orientation apparatus and hole finder device for a wireline logging tool string. In some embodiments the carriage includes a protection structure which extends longitudinally around a wheel of the apparatus to thereby prevent a side of the wheel from contacting a wall of the wellbore. In some embodiments an orientation apparatus and hole finder are arranged so that the orientation apparatus orientates the hole finder device in the wellbore so that a tip of a nose section of the hole finder is elevated above a low side of the wellbore by a height and offset from and above a longitudinal axis of the tool string.

A device for stabilizing pressure inside a gear's housing or a wheel's hub includes a bladder, and a conduit coupled to the bladder and coupleable to a volume containing a lubricant. The bladder includes a chamber having a volume, and is configured such that the chamber's volume increases as a fluid enters the chamber, and decreases as fluid leaves the chamber. The conduit includes a first end positionable adjacent the lubricant containing volume, a second end coupled with the bladder, and a passage between the first and second ends, and is configured to hold fluid disposed in the passage and direct the fluid between the first and second ends. When the conduit is coupled to the lubricant containing volume, the volume of the bladder's chamber, the passage of the conduit and the lubricant containing volume are isolated from the ambient environment.

A sensor transportation apparatus comprises at least one engagement structure to connect the sensor transportation apparatus to the sensor assembly, a pair of wheels arranged to rotate about an axis of rotation substantially perpendicular to a longitudinal axis of the sensor assembly when the transportation apparatus is connected to the sensor assembly, and an orientation structure comprising the pair of wheels and an orientation projection extending between the pair of wheels. Lateral extremities of the pair of wheels and the orientation projection together define a curve extending circumferentially around a portion of the circumference of the elongate sensor assembly. A rotational centre of the curve is offset from a central axis of the elongate sensor assembly and a rotational axis of the pair of wheels is above the central axis of the elongate sensor assembly when the sensor transportation apparatus is substantially horizontal.
