Abstract
A composition including a coated nanoparticle including a nanoparticle and a cross-linked carbohydrate-based coating and an ion selected from the group consisting of Li+, Na+, K+, Rb+, Cs+, Be2+, Mg2+, Sr2+, Ba2+, and mixtures thereof; methods of making and using the composition; and systems including the composition.
Claims18
A nanoparticle composition for treatment of a subterranean formation, the nanoparticle composition comprising:
- a coated nanoparticle comprising a nanoparticle and a cross-linked carbohydrate-based coating, wherein the cross-linked carbohydrate-based coating is the reaction product of a cross-linking reaction between an epoxide-based compound and a carbohydrate;
- and
- an ion selected from the group consisting of Li+, Na+, K+, Rb+, Cs+, Be2+, Mg2+, Ca2+, Sr2+, Ba2+, and mixtures thereof.
