A method for dissipating force within a tubing string including providing a severing device to a desired location within a tubing string; a cut zone along the length of the tubing, and a housing disposed along the length of tubing and sized to enclose the cut zone therein, wherein the housing includes a first end and a second end each forming a housing shoulder, severing the tubing at the cut zone using the severing device creating a first tubing section and a second tubing section; wherein the first tubing section and the second tubing section slide apart within the housing.

An openhole interval of a well may be sealed by deploying a liquified phase transformation material to the openhole interval and allowing it to harden. In at least one example, this may be performed in a single step of building and maintaining pressure. The pressure may rupture a membrane, to introduce a fluid into a chamber with a reactive material (e.g. powder) in a delivery chassis, whereupon the fluid may exothermically combine with the reactive material to liquify the solid phase transformation material. The same applied pressure may also deliver the liquified phase transformation material to a deployment chassis, which then distributes the liquified phase transformation material under pressure to the openhole interval of the well. Various delivery chassis, deployment chassis, and related compositions and methods are disclosed as well.
