Abstract

Packoff seals and processes for using same. In some examples, the packoff seal can include a first end cap and a second end cap, a first insert and a second insert, a first deformable element disposed between the first end cap and the first insert, a second deformable element disposed between the second insert and the second end cap, and a third deformable element disposed between the first insert and the second insert. The first end cap, the first deformable element, the first insert, the third deformable element, the second insert, the second deformable element, and the second end cap together can form a body having a bore extending therethrough. The first deformable element, the second deformable element, and the third deformable element can have a compressive strength that is less than a compressive strength of the first and second inserts.
