Abstract
Provided is an expandable metal plug for use in a wellbore tubular. The expandable metal plug, in one aspect, includes a downhole member positionable proximate a plug and abandonment section in a wellbore tubular, wherein at least a portion of the downhole member comprises a metal configured to expand in response to hydrolysis to seal the wellbore tubular
Claims38
An expandable metal plug for use in a wellbore tubular, comprising:
- a downhole member positionable proximate a plug and abandonment section in a wellbore tubular,
- wherein at least a portion of the downhole member comprises a metal configured to expand in response to hydrolysis to seal the wellbore tubular.
A method for plugging and abandoning a well system, comprising:
- positioning an expandable metal plug proximate a plug and abandonment section in a wellbore tubular, the expandable metal plug including a pre-expansion downhole member, wherein at least a portion of the pre-expansion downhole member comprises a metal configured to expand in response to hydrolysis to seal the wellbore tubular;
- and
- subjecting the pre-expansion downhole member to a wellbore fluid to expand the metal into contact with the wellbore tubular and thereby form an expanded metal plug the wellbore tubular.
A well system, comprising:
- a wellbore tubular positioned within a wellbore in a subterranean formation;
- an expanded metal plug positioned proximate a plug and abandonment section in the wellbore tubular, the expanded metal plug including a downhole member comprising a metal configured to expand in response to hydrolysis, the downhole member having expanded radially into contact with the wellbore tubular to plug the wellbore tubular.
