Abstract
An apparatus for installation in a borehole comprises a well component and a sleeve. The well component has a through-bore and is permeable to the borehole. For example, the well component can be a well screen having a perforated basepipe with a filter disposed thereabout or can be a liner defining a plurality of openings therein. The sleeve is disposed external to the well component. The sleeve is at least temporarily impermeable to obstruct the well component during run in the borehole and becomes permeable in response to an agent, such as a hydrochloric acid, a hydrofluoric acid, an acid stimulation, a wellbore fluid, or a drilling fluid, for example.
