Abstract
Reverse circulation cementing of a liner in a wellbore extending through a subterranean formation is presented. A running tool with expansion cone, release assembly, annular isolation device, and reverse circulation assembly is run-in with a liner. The annular isolation device is set against the casing. A valve, such as a dropped-ball operated sliding sleeve valve, opens reverse circulation ports for the cementing operation. The liner annulus is cemented using reverse circulation. The expandable liner hanger is expanded into engagement with the casing. Conventional circulation is restored. The running tool is released and pulled from the hole.
