Abstract

A two-stage packer and method for sealing an annulus in a wellbore is provided. The packer may be set by a force which will not cause a sealing element to buckle, collapse, or otherwise fail. In one aspect, the packer comprises a body having a sealing element and shoulder disposed there-around, and a slideable member slideably arranged on the body, the slideable member having a first surface disposable beneath the element to increase the inner diameter thereof and a second surface disposable against an end of the element to increase the outer diameter thereof. The method comprises running a body into the wellbore, the body comprising a sealing element and a slideable member slideably disposed there-around, wherein the slideable member comprises a first surface and a second surface; forcing the first surface beneath the element to increase the inner diameter thereof; and forcing the second surface against an end of the element to increase the outer diameter thereof.
