Abstract
A tubing string may include a swellable metal material for providing a seal downhole. The swellable metal material may react with a silica material and a water-based fluid to cause the swellable metal material to swell and form a seal within a flow path defined in part by the tubing string.
Claims16
An apparatus comprising:
- an oilfield tubular positionable downhole;
- and
- a swellable metal material positioned proximate a surface of the oilfield tubular for swelling and causing a fluid seal within a flow path defined in part by the oilfield tubular in response to the swellable metal material being in contact with a water-based fluid,
- wherein the swellable metal material includes an amorphous silica,
- and wherein the swellable metal material is configurable to react with the amorphous silica and the water-based fluid to result in a final product that is a metal-silicate-hydrate.
2 more elements
An apparatus comprising:
- an oilfield tubular positionable downhole;
- a swellable metal material at least partially surrounding a surface of the oilfield tubular;
- a silica material positioned proximate to the swellable metal material for reacting with the swellable metal material and a water-based fluid to result in a final product that is a metal-silicate-hydrate, wherein the silica material is at least partially encapsulated within a degradable coating.
A method for forming a seal in a wellbore comprising:
- providing a swellable sealing element that is at least partially comprised from a swellable metal material;
- providing a silica material, wherein the silica material is an amorphous silica;
- exposing the swellable sealing element to a water-based fluid, wherein the swellable metal material swells in response to undergoing a chemical reaction with the water-based fluid and the silica material to form a metal-silicate-hydrate.
