Abstract
Official abstract text for this publication.
A eutectic composite may be utilized in oil and gas servicing. For example, a method of making such a composite may include: crosslinking a mixture including a polymer, a metaphosphate salt, and a plurality of eutectic alloy particles to yield a eutectic composite; and producing a plurality of eutectic composite particles from the eutectic composite. Furthermore, an example composition may include: a cement; water; and a plurality of eutectic composite particles including eutectic alloy particles dispersed in a polymer crosslinked with a metaphosphate salt.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: introducing a cement slurry into a wellbore penetrating a subterranean formation, wherein the cement slurry comprises a cement, water, and a plurality of eutectic composite particles that comprise eutectic alloy particles dispersed in a polymer crosslinked with a metaphosphate salt; and allowing the cement slurry to set to a concrete in a downhole zone of interest. 2. The method of claim 1 , wherein the downhole zone of interest is an annulus between a wellbore wall and a tubular therein, an annulus between two tubulars, a microannulus, or a combination thereof. 3. The method of claim 1 , wherein the metaphosphate salt comprises sodium hexametaphosphate, sodium trimetaphosphate, or a combination of sodium hexametaphosphate and sodium trimetaphosphate. 4. The method of claim 1 , wherein the eutectic alloy comprises a bismuth-tin alloy, a bismuth-lead alloy, a bismuth-tin-lead alloy, or any combination thereof. 5. The method of claim 1 , wherein the volume ratio of the polymer crosslinked with the metaphosphate salt to the eutectic alloy is about 3:7 to about 9:1. 6. The method of claim 1 , wherein the plurality of eutectic composite particles have a specific gravity of about 1 g/cm 3 to about 4 g/cm 3 .
