Abstract
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.
Claims6
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.
