Abstract
A system includes a seal bushing that is locked into a pup joint, which is part of a liner assembly including an expandable liner hanger. The system also includes an expansion tool that is connected to a drill pipe. The expansion tool includes an expansion cone attached to the slick joint. The slick joint can slide within the bore of the seal bushing. A ball is dropped into the drill pipe and lands on a seat of the expansion tool to increase hydraulic pressure. The ball and the seal bushing can avoid pressurizing an entire liner connected below the pup joint. When the expansion cone moves through the liner hanger at least in part under the effect of pressure, the liner hanger is expanded and anchored to a base casing.
