Abstract: The present invention discloses apparatus and methods for use in wellbores that comprise an inflatable element. The inflatable element is adapted for inflation by gravel. One embodiment of the invention is a method of sealing an annulus in a well that comprises expanding the inflatable element with a gravel laden slurry. The inflatable element comprises a passageway communicating between an exterior and an interior of the inflatable element. The inflatable element is capable of being connected to a sand screen and the inflatable element can be inflated with the gravel laden slurry during a gravel packing of the well.

Abstract: A service/completion liner having a plurality of downhole selectable indicating tools and being used in sand control (gravel pack) placement systems in conjunction with a straddle packer service tools or with conventional crossover type service tools. Each indicating collar has a downhole selectable indicating collar providing a robust, landing profile for precisely locating and maintaining service tool position during well treatment operations. The landing collars accommodate hydraulic and/or thermal effects commonly referred to as tubing move effects which are the principle cause of tool position error and excessive seal wear. The landing collar is downhole convertible between a pass through (Go) and non pass through (No-go) condition by simple upward and downward cycling via the tool running and treatment fluid tubing and a shifting tool, which may also be referred to as a set down collet. The shifting/set down collet is also used to open and close a downhole sliding sleeve valve and may be an integral part of an injection tool or a tool for gravel or fracture packing. A sliding sleeve valve design and a straddle packer configuration that protects the primary PBRs in the gravel pack system and also protects the sliding sleeve while sand is placed in the screen casing annulus.

Abstract: A by-pass valve mechanism for a well treatment tool having at least one flow sensitive element, permitting by-pass of well fluid past the flow sensitive element of the well treatment tool during conveyance of the well treatment tool to treatment depth within a well. A valve housing adapted for connection with a well tool defines an internal flow passage and has at least one by-pass port communicating well fluid between the flow passage of the service tool and the annulus between the well casing and the service tool. A sliding sleeve valve element is normally secured at its open position by shear elements permitting flow of well fluid through the and is moveable between an open position diverting fluid flow from within the service tool to the annulus and a closed position blocking the flow of well fluid through the by-pass port. The sleeve valve element is released and automatically closed by predetermined hydrostatic tubing or casing pressure or pump pressure. The by-pass valve mechanism may have a test pressure control system permitting pressure testing of a well without causing release and closure of the sleeve valve.
