Abstract:

Well screen assembly for permitting a plurality of pipe based well screen segments in an extended length production zone to be brought into operation simultaneously uses a ported connector sub to join each pair of screen segments so that the ends of the relatively large diameter perforated pipe base supports are attached to the connector's ends. Each screen also has solid internal pipe members of much smaller diameter which are joined to a central bore in the connector. Annular spaces between the internal pipe members and the pipe base supports communicate through the connector ports and permit flow from both screens to reach the inside of the inner pipe members when downhole perforations are made in only one of the inner pipe members.
