A well casing packer is provided that includes a seal mandrel having a first coupler, a second coupler, and a neck extending between the first coupler and the second coupler. A first compression body is slidably coupled to the seal mandrel at the first coupler. A second compression body is connected to the seal mandrel, and a compression lock ring connected to the first compression body. A packer seal is 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 a longitudinal movement of the seal mandrel with respect to the first compression body allows the second compression body and the compression lock ring to longitudinally compress and radially expand the packer seal.
