ABSTRACT:
A completion apparatus and method are illustrated to allow the use of an inflatable bridge plug system to be set in lower casing after the open-hole section has been drilled underbalanced. This is coupled with an assembly to deflate the plug which is run on the bottom of the completion liner. The completion liner is run downhole without having to kill the well to reduce possible formation damage from kill fluids. Sifter the open-hole section is drilled, the plug is run in the hole on coiled tubing and set. Heavy fluids are then circulated above the plug without its being applied to the open-hole formation. The liner for the open-hole section is run in the well with a deflation tool, which ultimately engulfs the deflated plug using the mechanical support associated with the plug to facilitate the enveloping procedure. After envelopment, setdown weight releases the anchor for the plug and the assembly is run in the hole with circulation through the plug to facilitate advancement.
