Abstract
Official abstract text for this publication.
The Patent Application discloses an in-situ swellable composition suitable for use in subterranean wells. The swellable composition may comprise a composite material. The composite material swells on contact with water due to chemical reaction of the composite material.
First claim
Opening claim text (preview).
We claim: 1. A swellable composition, suitable for use in subterranean wells, comprising: a composite material, wherein the composite material comprises an inorganic material and dissolvable metals, which swell on contact with water due to chemical reaction of the composite material; and an inert oxide, wherein the swellable composition has porosity from about 0.5% to about 10%. 2. The composition of claim 1 , wherein the composite material further comprises a reactive oxide. 3. The composition of claim 1 , wherein the dissolvable metal comprises at least one of Mg, Al, or their alloys. 4. The composition of claim 2 , wherein the reactive oxide comprises at least one of silicon oxide, Na 2 Si 2 O 3 , Al 2 SiO 5 , Al 2 O 3 . 5. The composition of claim 1 , wherein the inert oxide comprises zeolite or molecular sieves. 6. The composition of claim 1 , wherein the inert oxide comprises at least one of silicate, ZrO 2 . 7. The composition of claim 1 , wherein the inert oxide volume percent is from about 10% to about 40%.
