Abstract
An extrudable ball seat (36) is configured to be secured along a well tubing (34). The extrudable ball seat (36) comprises a larger diameter section (42) and a smaller diameter (44) section connected by a conical section (46). The conical section (46) has an internal seating surface (48) for receiving a corresponding element, e.g. a ball (52), in sealing engagement. The extrudable ball seat (36) facilitates controlled extrusion of the element following a pressure actuation procedure by providing the smaller diameter section (44) with sufficient ductility to enable extrusion of the element under an increased predetermined pressure. Additionally, the extrudable ball seat comprises at least one notch (56), e.g. a plurality of grooves (58), positioned to initiate crack propagation and thus extrusion of larger elements.
