Abstract: A sealing assembly is disclosed, the sealing assembly comprising a plurality of components including an upper sealing element and a lower sealing element, the sealing assembly configured to encircle a tubular string positioned within a casing of a wellbore. The sealing assembly is configured to be actuatable to extend sealing elements between the tubular string and an inner surface of the casing to form a fluid seal between the tubular element and the inner surface of the casing.

Abstract: A cut-to-release packer can include a bottom sub, a wedge assembly, a mandrel, and a load diverting snap ring. The mandrel extends within the wedge assembly. The mandrel can include a support portion with a first cross-sectional thickness and a cut zone portion with a second cross-sectional thickness less than the first cross-sectional thickness, wherein the cut zone portion is disposed between the bottom sub and the support portion. Both the mandrel and the wedge assembly can be coupled to the bottom sub. The load diverting snap ring can be engaged with the mandrel along the support portion, wherein the load diverting snap ring facilitates transfer of tensile load between the wedge assembly and the support portion of the mandrel.
