Abstract
Abstract A screen device is provided for use in a subterranean well and is carriable within the well on a tubular conduit. The screen has an elongated outer housing with a plurality of flow passageways extending through the housing. An inner perforable cylindrical mandrel with upper and lower ends has at least one of the ends securable with a conduit member of the tubular conduit. The mandrel longitudinally extends through the interior of the housing and is secured against movement relative to the housing. A central passageway in the mandrel communicates with the tubular conduit for transmission of fluid. Prior to perforation of the mandrel, the screen device prevents fluid flow between the flow passageways and the central passageway of the mandrel. Subsequent to perforation of the mandrel, the screen device permits transmission of fluid between the flow passageways, the central passageway and the tubular conduit. The screen device is perforated by means of a conventional jet-producing perforation gun introduced into the well on an auxiliary conduit, such as a wireline, through the tubular conduit. The screen device permits selective production of multi-lobes within one or more production zones in the well.
