Abstract: Force balancing adjusts hydraulic fluid pressure in an upper piston area of a Rotating Pressure Control Device (RPCD) that has an inner housing rotatably engaged within an outer housing by an upper bearing and a lower bearing. The hydraulic fluid pressure is adjusted to balance net force in a upper piston area and a lower piston area. The fluid pressure adjustment creates a force differential that balances the total load transmitted through the upper bearing and the lower bearing and thereby extends the life of the sealing element and bearings. Additionally, a wear indicator signals the end of the useful life of the drill pipe sealing element.

Abstract: A tubing string resettable packer is conditioned for initial wireline installation in a well utilizing an adapter within a mandrel carrying the slip assembly of the packer and frangible connecting means between the sealing assembly and mandrel to place the sealing assembly in an alternate transport condition for first being set by means of a wireline device. Thereafter, the tubing string may be connected to the packer downhole to release the packer for resetting in a different position.
