Abstract
Well completion apparatus and associated methods of completing wells provides repositioning of sand control screens and perforating guns without requiring movement of a packer in the wellbore. In a preferred embodiment, a well completion apparatus has a packer, a release apparatus, a telescoping expansion joint, a ball catcher, a sand control screen, and a perforating gun. In another preferred embodiment, a well completion method includes the steps of lowering a packer, release apparatus, telescoping expansion joint, ball catcher, sand control screen, and perforating gun into a well, perforating the wellbore casing, dispensing a sealing ball into the release apparatus, applying pressure to release the release apparatus, and applying pressure to expand the telescoping joint.
