Abstract
A viscoelastic fluid composition includes a viscoelastic surfactant composition ranging from about 0.1 wt. % to about 10 wt. % based on a total wt. % of the viscoelastic fluid composition. The viscoelastic fluid composition further includes crystalline sodium sulfate cellulose (NaSC) nanoparticles ranging from about 0.1 wt. % to about 10 wt. % based on the total wt. % of the viscoelastic fluid composition.
Claims21
A viscoelastic fluid composition comprising:
- a viscoelastic surfactant composition ranging from about 0.1 wt. % to about 10 wt. % based on a total wt. % of the viscoelastic fluid composition, wherein the viscoelastic surfactant composition is selected from a group consisting of betaines, modified betaines, alkylamidobetaines, sultaines, modified sultaines, alkylamidopropyl sultaines, and combinations thereof;
- and
- crystalline sodium sulfate cellulose (NaSC) nanoparticles ranging from about 0.1 wt. % to about 10 wt. % based on the total wt. % of the viscoelastic fluid composition.
A method comprising:
- mixing a viscoelastic surfactant composition and NaSC nanoparticles to form a viscoelastic fluid composition comprising:
- the viscoelastic surfactant composition ranging from about 0.1 wt. % to about 10 wt. % based on a total wt. % of the viscoelastic fluid composition, wherein the viscoelastic surfactant composition is selected from a group consisting of betaines, modified betaines, alkylamidobetaines, sultaines, modified sultaines, alkylamidopropyl sultaines, and combinations thereof;
- and
- the NaSC nanoparticles ranging from about 0.1 wt. % to about 10 wt. % based on the total wt. % of the viscoelastic fluid composition;
- and
- providing the viscoelastic fluid composition to a wellbore to treat a subterranean formation.
3 more elements
A system comprising:
- one or more vessels disposed in a subterranean formation, wherein the one or more vessels contain a viscoelastic fluid composition comprising:
