Claim:
A well conveyance apparatus ( 7922 , 7924 ) for conveying equipment into a wellbore possessing at least one hydraulic seal ( 7900 ) that is rotatably attached to a mandrel portion ( 7780 ) which forms a movable and slidable hydraulic seal against an interior portion a borehole casing ( 6782 ) located within a wellbore in a geological formation that is caused to move by the application of pressurized wellbore fluids against the seal, said apparatus further comprising: (a) a bearing assembly ( 8657 , 8677 ) having an inner race ( 8659 , 8679 ) attached to said mandrel portion ( 8414 ) and an outer race ( 8663 , 8683 ) that is bonded to an interior portion of said hydraulic seal that allows said seal to rotate within said casing; (b) a vibratory means ( 8769 ) attached to said mandrel portion ( 8414 ) that vibrates said movable and slidable seal ( 8751 , 8763 ); (c) at least one sensor array ( 8615 , 8617 , 8629 ) attached to said mandrel portion ( 8414 ) to determine leakage level of said wellbore fluids passing by said hydraulic seal; and (d) a computer system ( 26 ) to process said measurement information that is used in part to control said vibratory means ( 8769 ) to minimize wear on the portion of the movable and slidable hydraulic seal making contact with the interior of said borehole casing ( 8408 , 8432 , 8603 , 8609 , 8653 , 8673 , 8703 , 8715 , 8753 , 8765 , 8903 , 8925 , 8953 ).
