Abstract
Disclosed herein are aspects of a gas lift mandrel plug for use in a wellbore. In one embodiment, a gas lift mandrel plug may comprise an elongate member having a proximal end and a distal end, wherein the elongate member comprises a metal sealant configured to expand in response to hydrolysis, and wherein the elongate member is configured to seal a side pocket of a wellbore tubular in response to hydrolysis.
Claims19
A gas lift mandrel plug for use in a wellbore, comprising:
- an elongate member having a proximal end and a distal end;
- wherein the elongate member comprises a body of monolithic metal sealant configured to expand in response to hydrolysis, the body of monolithic metal sealant having a length substantially greater than a width;
- and
- wherein the expanded metal elongate member is configured to seal against an internal diameter of a side pocket of a wellbore tubular in response to hydrolysis, and further wherein during the expansion, the body of monolithic metal sealant is configured to go from metal to micron-scale particles that are larger and lock together.

A well system, comprising:
- a wellbore tubular;
- a side pocket located within the wellbore tubular;
- a gas lift mandrel plug positioned in and sealing the side pocket, the gas lift mandrel plug comprising:
- an elongate member having a proximal end and a distal end, wherein the proximal end is configured to connect with an intervention tool;
- and
- wherein the elongate member comprises a body of monolithic metal sealant configured to expand in response to hydrolysis, the body of monolithic metal sealant having a length substantially greater than a width, and further wherein during the expansion, the body of monolithic metal sealant is configured to go from metal to micron-scale particles that are larger and lock together.
3 more elements
A method of using a gas lift mandrel plug in a well system, the method comprising:
- removing a gas lift valve from a side pocket located within a wellbore tubular;
- positioning a gas lift mandrel plug into the side pocket, the gas lift mandrel plug comprising an elongate member having a proximal end and a distal end, wherein the proximal end is configured to connect with an intervention tool;
- wherein the elongate member comprises a body of monolithic metal sealant configured to expand in response to hydrolysis, the body of monolithic metal sealant having a length substantially greater than a width;
- and
- wherein the elongate member is configured to seal a side pocket of a downhole casing in response to hydrolysis, and further wherein during the expansion, the body of monolithic metal sealant is configured to go from metal to micron-scale particles that are larger and lock together.
