Abstract: A hydraulic technique for applications with inflatable packers keeps the inflatable packer in a stretched-out condition despite the forces imposed on the packer by circulating fluids. This prevents the inflatable packer from swabbing due to the force of circulating fluids.

Abstract: An apparatus for controlling sand production within a wellbore completed to a subterranean reservoir is disclosed. The apparatus will include a base supporting member that has a series of perforations included thereon. A jacket member is disposed about the base supporting member, with the jacket member being a helical member with overlapping loops forming multiple passages for the flow of a subterranean gas and fluid. A protective member disposed about the jacket may also be included, with the protective member having a series of perforations formed thereon.
