Abstract: Provided, in one aspect, is a ball seat release apparatus. The ball seat release apparatus, according to this embodiment, includes a shear sleeve having a recess pocket and a ball seat body slidingly engaged within the shear sleeve, the ball seat body configured to move from a first linear position to a second linear position. The ball seat body further includes a longitudinal fluid passageway, a ball seat located in the longitudinal fluid passageway, one or more first fluid bypass ports coupling the longitudinal fluid passageway and an exterior of the ball seat body, the one or more first fluid bypass ports located on a first side of the ball seat, and one or more second fluid bypass ports coupling the longitudinal fluid passageway and the exterior of the ball seat body, the one or more second fluid bypass ports located on a second opposing side of the ball seat.

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.

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.
