US 2022/0186575 A1 · NON-EXPANDING LINER HANGER

Abstract

Methods and apparatus for positioning a non-expandable liner hanger in a wellbore. A liner is coupled to the liner hanger, wherein the liner hanger comprises: a conduit body; and a reactive metal sealing element disposed on the conduit body, wherein the reactive metal sealing element comprises a reactive metal having a first volume. An example method includes contacting the reactive metal with a fluid that reacts with the reactive metal to produce a reaction product having a second volume greater than the first volume; and contacting a surface adjacent to the reactive metal sealing element with the reaction product to form a seal against the surface and to anchor the liner hanger from the surface, wherein anchoring the liner hanger to the surface suspends the liner in the wellbore.

A method for suspending a liner comprising:

positioning a non-expandable liner hanger in a wellbore, wherein a liner is coupled to the liner hanger, wherein the liner hanger comprises:
a conduit body;
and
a reactive metal sealing element disposed on the conduit body, wherein the reactive metal sealing element comprises a reactive metal having a first volume;
contacting the reactive metal with a fluid that reacts with the reactive metal to produce a reaction product having a second volume greater than the first volume thereby anchoring the liner hanger;
wherein the reaction product is a metal hydroxide, metal oxide, or a combination thereof;
and
contacting a surface adjacent to the reactive metal sealing element with the reaction product to form a seal against the surface and to anchor the liner hanger from the surface with the reaction product, wherein anchoring the liner hanger to the surface suspends the liner in the wellbore.
