Publication number: 20090291864Abstract: The present invention provides aqueous viscoelastic compositions comprising a cleavable anionic surfactant which is a sulphonate and possibly also an electrolyte. The cleavable surfactants useful in the present invention comprise a chemical bond, which is capable of being broken under appropriate conditions, to produce oil soluble and water soluble products typically having no interfacial properties and surface activity compared with the original surfactant molecule. Further, the rheological properties of the aqueous viscoelastic composition are usually altered upon cleavage of the cleavable surfactant generally resulting in the elimination of the viscosifying, viscoelastic and surfactant properties of the composition. Aqueous viscoelastic compositions in accordance with the present invention are suitable for use in oil-field applications, particularly for hydraulic fracturing of subterranean formations.Type: ApplicationFiled: May 15, 2009Publication date: November 26, 2009Applicant: Schlumberger Technology CorporationInventors: Robert Seth Hartshorne, Trevor Lloyd Hughes, Timothy Gareth John Jones, Gary John Tustin, Jian Zhou
