Abstract
A method for reverse circulation cementing of a liner in a wellbore extending through a subterranean formation is presented. A running tool with expansion cone, 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 valve, opens reverse circulation ports for the cementing operation. The liner annulus is cemented using reverse circulation. An expandable liner hanger, if present, is expanded into engagement with the casing. The running tool is released and pulled from the hole.
