Disintegrating Expand in Place Barrier Assembly

摘要

A clad is expanded with a variable swage or other ways to create a seat for an object to obstruct the passage therethrough while at the same time expanding at least a part of the clad into a surrounding tubular for support and sealing. The exterior of the clad can have grit to enhance the grip. A perforating gun can be delivered in the same trip with the clad. After the swage passes through the clad the gun is positioned and fired, the bottom hole assembly is retrieved and the ball is dropped from the surface onto the seat formed in the clad with expansion or with some other means. A treating operation against the clad and into the surrounding formation can then take place. The process can be repeated preferably in a bottom up direction until the formation is fully treated. The clads and objects landed on the clads disintegrate with time or borehole exposure.

主权项

1. A treatment method for a subterranean formation from a borehole, comprising:
delivering at least one sleeve to at least one location in the borehole; expanding a first portion of the sleeve such that said first portion finds support on a borehole wall while creating a transition between said first and a second portion that defines a seat for an object around a passage through said sleeve; delivering at least one object on said seat to block said passage through said sleeve; performing a treating operation with pressure on said object on said seat.
