摘要
Valve systems and methods for inserting the valve system into a casing for a downhole environment are provided. The valve system includes a mandrel, a check valve assembly, and a sealing element containing swellable polymeric material. The check valve assembly is coupled to the mandrel and operable to provide a fluid flow only in a primary direction through a passageway of the mandrel. The sealing element is located on an outer surface of the mandrel. In some examples, the sealing element includes slip buttons or other gripping elements located on the swellable polymeric material.
