Abstract
A retrievable screen apparatus provides increased filtration in a retrievable screen disposed within a receptacle, the receptacle being positioned in a subterranean well. The receptacle has a lower filtration screen attached thereto for filtering larger particles, such as gravel and proppant, from fluid flow within the well. Thus, the retrievable screen may be retrieved and replaced, leaving the receptacle operatively positioned in the well.
