Expandable support ring for packing element containment system

A packing element containment system includes a support member extending from a first end to a second end. One of the first and second ends includes a support ring engagement section. A support ring is carried by the support ring engagement section of the support member.

Residual pressure differential removal mechanism for a setting device for a subterranean tool

A pressure actuated module associated with a subterranean tool is set with pressure in the well annulus supplemented by added pressure. The addition of pressure to the hydrostatic opens access to a setting piston that is referenced to a low pressure chamber. The piston strokes to a travel stop reducing the volume of the atmospheric chamber while setting the tool. After the tool is set the annulus is communicated to the low pressure reference chamber for the actuating piston to remove a residual net force on the setting piston after the set. One way to do this is to sequentially break multiple rupture discs at different pressures. Another is to have a degradable member in the atmospheric chamber. A piston is fixed in place during setting, and shifts with the application of additional pressure allowing pressure to pass through a port between the annulus and the atmospheric chamber.

Subterranean Packer Sealing System Load Diverter

A mandrel and a packer outer assembly are formed to create spring compartments on opposed sides of a sealing element. The outer assembly is shear pinned to the mandrel to minimize spring travel during setting. Once set in the normal way the presence of the springs transfers load and sustained loads through the connected tubular string in either direction. A load coming from downhole and acting in an uphole direction first compresses the spring located uphole from the sealing assembly so that the loading goes behind the sealing assembly and into the upper spring and ultimately to the upper slips. The reverse happens when the force is coming from uphole of the sealing assembly and acting in a downhole direction. The springs can be a coil, a stack of Belleville washers, fluid pushed through an orifice, a resilient material or a contained compressible fluid, to name some examples. 1. A packer for subterranean use against a borehole wall , comprising:a mandrel supporting an outer assembly further comprising a sealing element flanked on opposing sides with an uphole and a downhole slip assembly;said mandrel, after said sealing element and slip assemblies are engaged to the borehole wall, transmitting at least a portion of applied forces thereto in either an uphole or downhole direction, in an alternate path that avoids incremental loading of said sealing assembly.2.
