Abstract: A packer has a swellable element and has end rings and compressible elements at each end of the swellable element. The packer may be first set using internal bore pressure to compress one of the compressible elements against one of the end rings with a first hydraulic setting mechanism. The packer may then be set a second time using annulus pressure to compress against the other compressible element with a second hydraulic setting mechanism. Either way, the compressible elements are compressed to expand out to the borehole and to limit extrusion of the swellable element outside the compressed elements.

Abstract: A device and method to control the rate of radial expansion of a compressible sealing element on a packer over the longitudinal length of the sealing element. By varying the rate of compression of the element, the rate of radial expansion of the corresponding portions of the element may also be controlled. Additionally, the rate of radial expansion may also be controlled by controlling the direction and amount of radial expansion along the length of the sealing by reinforcing certain portions of the sealing element while decreasing the rigidity of the reinforcement for other portions.

Abstract: A method and apparatus for a downhole tool. In one embodiment, a method of deploying a tool in a wellbore is disclosed and consists of installing a tool body at an upper end of a tubular string extending from a wellbore, the body having at least one control line groove formed on its outer surface for housing at least one control line, the at least one control line housed therein; providing an assembly, the assembly strung on the at least one control line and including a compressible element with at least one ring on each end thereof; at least one ring on each end of the element; a locking ring at an upper end of the assembly. The method further includes installing the assembly over the body whereby the at least one control line is housed between the body and the assembly.
