Abstract:
1. A retrievable screen for fitting within the bore of a pipe comprising: a perforated tubular screen body having an inner sidewall surface, a bottom and an open top, the screen body sized to fit within the bore of the pipe; a fish neck projecting outwardly from the open top and generally positioned along longitudinal axis of the screen body; at least one planar support plate extending between the fish neck and the screen body, the plane of which is generally parallel to the longitudinal axis, each of the at least one planar support plate having a first edge attached thereby to the fish neck, and having an opposing second edge attached thereby to the inner sidewall surface of the screen body; and a releasable connection for interconnecting the retrievable screen with the pipe, wherein a retrieving force applied to the fish neck is transferred to the screen body and wherein the retrieving force effects disconnection of the releasable connection, thereby permitting retrieval of the retrievable screen from the bore of the pipe.
