Abstract

A packer () for establishing sealing engagement with a surface disposed in a wellbore includes a packer mandrel () and a seal assembly () slidably disposed about the packer mandrel (). The seal assembly () has a running position and a radially expanded sealing position. A piston () is slidably disposed about the packer mandrel () and operably associated with the seal assembly (). A collet assemblyis disposed about the packer mandrel () and is releasably coupled to the piston () such that radially inwardly shifting at least portion of the collet assembly () decouples the collet assembly () from the piston () allowing the piston () to shift longitudinally relative to the packer mandrel () which operates the seal assembly () from the running position to the radially expanded sealing position, thereby setting the packer ().
