Abstract
A zonal isolation washpipe system for isolating a production zone which intersects a wellbore from communication with the surface comprises a seal assembly adapted for sealing engagement within the bore of a well packer disposed about the external circumference of one end of a tubular washpipe, a releasable connector system on the other end of the washpipe which provides means for retrieval of the washpipe from the well bore is placed in sealing engagement by a releasable telescoping expansion joint which is resistant to undesired or premature extension. When it is desired to place the isolated zone on production, a tubing perforator, such as a jet perforator which is commonly known in the art is lowered into the bore of the wash pipe to a location adjacent previously formed perforations in the casing and the wash pipe is perforated. A method for gravel packing a well using the described tools is also presented.
