Systems and methods of the present disclosure relate to storing carbon dioxide (CO) underground. A method includes contacting a metal tool with the COand forming hydrated metal carbonates (HMCs) on the tool due to contact of the COwith the metal of the tool. Expansion of the tool occurs due to formation of the HMCs.

Hydrated metal carbonate for carbon capture and underground storage

Provided is a downhole tool, a well system, and a method. The downhole tool, in one aspect, includes an expandable metal member positioned about a structure, the expandable metal member comprising a metal configured to expand in response to hydrolysis. The downhole tool, in accordance with this embodiment, further includes a dissimilar cathodic electric conductor isolated within the expandable metal member, the dissimilar cathodic electric conductor configured to initiate a galvanic corrosion effect to increase an expansion rate of the expandable metal member when a reactive fluid comes into contact with the dissimilar cathodic electric conductor and the expandable metal member.

Delayed acceleration of expandable metal reaction with galvanic corrosion

A variety of methods/systems/apparatus/compositions are disclosed, including, in one embodiment, a downhole tool (for use in a borehole) having a mandrel, a sealing element including metal particles disposed about the mandrel, and a piston to move a containment component of the downhole tool in an axial direction to move the metal particles in the axial direction, thereby displacing the metal particles in a radial direction toward a borehole wall to expand the sealing element in the radial direction to form a seal between the downhole tool and the borehole wall.

Downhole tool for sealing in openhole washouts

A tubular control conduit is disposed in a wellbore having a retractable segment and an abandonable segment, each having an inner bore. Upon retraction of the retractable segment an obstruction member is actuated to form a seal thereby preventing the flow of fluid past the obstruction member in the inner bore of the abandoned segment. Cement is then poured into the wellbore thereby covering the abandoned segment of the tubular control conduit.

Actuatable obstruction member for control lines

A downhole tool for coupling an electrical connection in the wellbore comprising a locator sub and a receptacle sub. The locator sub can be conveyed into the wellbore with a workstring. The receptacle sub can be coupled to a lower completion with at least one downhole tool. Workstring manipulation can insert the locator sub into the receptacle sub to provide an electrical connection between a resilient connector on the locator sub and ring connector within the receptacle sub. A fluid source fluidically connected to the electrical connection can flush out trapped wellbore fluids via a fluid pathway. The electrical connection can electrically couple to a control system at surface to the at least one downhole tool.
