ABSTRACT:
A pump-out plug catcher is disclosed for use within a wellbore to contain a released pump-out plug. The catcher includes a body, pump-out plug retention devices, and an extension member which extends into the body. The body is provided with an axial bore extending therethrough and an enlarged hollow portion in communication with the bore. Pump-out plug retention devices are provided in an upper portion of the body and retain a pump-out plug across the bore until subjected to a predetermined pressure. The extension member is provided with an axial bore extending therethrough which is of a diameter less than pump-out plug. The released pump-out plug catcher apparatus is lowered into a wellbore and set below a retrievable packer assembly. A pump-out plug is connected to the catcher and fluid is introduced down the tubing to force the pump-out plug from its position. The pump-out plug then falls into and is retained in the enlarged hollow portion of the body, thereby allowing for the unrestricted free passage of fluids and objects through the pump-out plug catcher.
