A depressurization tool is described for use downhole in depressurizing an isolated zone. A decompression chamber containing a compressible fluid volume is described. The opening of the chamber is sealed with a closure that is configured to open upon application of a pressure differential across the opening. When used downhole within an isolated and nonpermeable wellbore zone, excessive ambient pressure will cause the closure to open and allow the chamber to fill with fluid at increased pressure, depressurizing the wellbore zone. The tool is useful in wellbore completion systems that include sliding sleeves.

A flexible fluid storage system for holding large volumes of fluid and a process and apparatus for the handling and transportation of the flexible storage system is provided. The flexible storage system includes a main storage bag with an attachment apron with fingers, a ground sheet, a lay flat tube for fluid circulation, a pressure release port, and fill/drain ports. The flexible storage system is configured for attachment to a trailer and reel system such that the flexible storage system can be mechanically rolled onto or off of a reel on a semi-truck trailer bed for easy transportation, deployment, and storage of the flexible storage system.

A packer with an equalizing valve for automatically equalizing the pressure above and below the packer element. The packer comprises a housing having an equalizing valve disposed therein. A packer element is disposed about the housing for sealingly engaging the wellbore. An equalizing valve is disposed in the housing and seals the housing to prevent flow therethrough when the packer element is actuated to engage the wellbore. The valve is movable in the closed position wherein communication through the housing is prevented to an open position so that the portion of the wellbore above the packer element may be communicated with a portion of the wellbore below the packer element while the element is in the set position so that pressure above and below the element may be equalized. Once the pressure is equalized, the packer can be unset and retrieved from the wellbore.
