US 11,028,666 B2 · Apparatus for isolating one or more zones in a well

Abstract

An isolation tool that is installed in a well by a setting tool to isolate at least a portion of the well. Preferably, the isolation tool is a plug and the plug and setting tool are configured to prevent premature setting of the plug. Preferably, the plug includes one or more portions that directly connect the plug to a setting tool wherein the one or more portions of the plug shear during setting of the plug in an operating position. In a most preferred form, the plug includes first and second longitudinally spaced portions that directly connect the plug to a setting tool wherein the first and second portions shear during setting of the plug in an operating position. In a most preferred form, the plug and setting tool are configured so that no portion of the setting tool shears during the installation of the plug, separation of the plug from the setting tool and removal of the setting tool.

An apparatus for installation in a well bore for isolating at least a portion of the well bore, said apparatus comprising:

a multi-piece plug configured to be installed in an operating position in a well bore by a setting tool detachably connected to the multi-piece plug, said multi-piece plug having a first portion and a second portion, said first portion is offset along a longitudinal axis of said multi-piece plug from said second portion, said first portion of said multi-piece plug being configured to engage a first portion of the setting tool to connect said multi-piece plug to the setting tool at a first location while said multi-piece plug travels in the well bore to the operating position, said second portion of said multi-piece plug being configured to engage a second portion of the setting tool to connect said multi-piece plug to the setting tool at a second location while said multi-piece plug travels in the well bore to the operating position, said first portion and said second portion of said multi-piece plug prevent premature setting of the multi-piece plug.

A bridge plug configured to be installed in a well bore in an operating position by a setting tool for isolating a portion of the well bore, said bridge plug comprising:

a multi-piece body configured to be installed in an operating position in a well bore wherein said multi-piece body is fixed to the well bore when installed in the operating position, said multi-piece body of said bridge plug having a first portion and a second portion, said first portion is offset along a longitudinal axis of said multi-piece body from said second portion, said first portion of said multi-piece body of said bridge plug being configured to engage a first portion of a setting tool to connect said multi-piece body of said bridge plug to the setting tool at a first location while said multi-piece body of said bridge plug travels in the well bore to the operating position, said second portion of said multi-piece body of said bridge plug being configured to engage a second portion of the setting tool to connect said multi-piece body of said bridge plug to the setting tool at a second location while said multi-piece body of said bridge plug travels in the well bore to the operating position, wherein said first portion and said second portion of said multi-piece body of said bridge plug are configured to shear during setting of said multi-piece body of said the bridge plug in the operating position.
