Abstract
Well screen having a base made of formed channels provides the strength of a pipe base screen but weighs less, costs less, and provides greater vertical flow area. The channels are perforated and are in continuous contact around the screen with the contiguous legs of adjacent channels being welded at their ends to each other and to the wrap wire. The screen is particularly useful in oil and gas wells where great torsional strength is needed.
