Abstract
An assembly method for a downhole screen is disclosed. In the preferred embodiment, the filtration layer is slipped over a perforated base pipe and an expansion technique is used to increase the base pipe diameter to the point where, preferably, an interference fit exists. The expansion can be fully underneath the filtration layer or can be done in discrete zones. The finished assembly can still be expanded further downhole, such as, for example, in open hole completions. An outer protective shroud can be employed over the filtration layer when the expansion of the base pipe occurs.
