Patent ID: 7287599

Claim:
A well casing packer comprising: a seal mandrel having a first coupler, a second coupler, and a neck extending between the first coupler and the second coupler; a first fixed compression body having the first coupler of the seal mandrel slidably disposed therein to the seal mandrel at the first coupler; a second compression body fixedly connected to the second coupler of the seal mandrel; a detachable compression lock ring disposed around the neck of the seal mandrel and fixedly connected to the first compression body such that the first coupler of the seal mandrel is slidingly retained within the first compression body; a packer seal disposed in surrounding relation to a portion of the neck of the seal mandrel and between the second compression body and the compression lock ring, such that the longitudinal movement of the seal mandrel with respect to the first compression body forces the second compression body to move toward the compression lock ring such that the packer seal is longitudinally compressed and radially expanded to form a seal against the well casing.
