Abstract
A well conveyance apparatus for conveying equipment into a wellbore possessing long-lasting movable and slidable hydraulic seals against the interior of a borehole casing located within a wellbore in a geological formation in the earth that is caused to move by the application of pressurized wellbore fluids against the seals. The seals are allowed to rotate on bearings about the tool mandrel to prevent the build-up of torque on the seals to minimize wear and to extend the life of the seals. Vibratory means are attached to the tool mandrel to vibrate the sealing portion of the seals, so as the extend the life of the seals and to minimize wear of the seals. Sensor arrays provide information to a computer system that is used to control the vibratory means, pressure relief valves, and other parameters to minimize wear of the hydraulic seals.
