    摘要: There is set forth herein a method for providing a nanoparticle array. A nanoparticle network can be provided by nanoparticles combined with surfactant micelle chains. The nanoparticle network can be provided by distributing metal nanoparticles in a surfactant solution and agitating the surfactant solution comprising the nanoparticles to form a gel comprising the nanoparticle network which can be characterized by a distributed array of nanoparticles combined with surfactant micelle chains within a fluid. The gel can comprise a fluid in a continuous phase and the nanoparticles in a discontinuous phase. Apparatus having arrays of nanoparticles are also set forth herein.

    摘要: Fluids viscosified with viscoelastic surfactants (VESs) may have their viscosities reduced (gels broken) by the direct or indirect action of a composition that contains at least one metal ion source and optionally at least one second source. An optional second source may be a chelating agent where at least one reducing agent source may be additionally optionally used. Another optional component with the metal ion source includes a second, different metal ion source. The breaking composition is believed to directly attack the VES itself, possibly by disaggregating or otherwise attacking the micellar structure of the VES-gelled fluid, and/or possibly by changing the chemical structure of the VES to give two or more products.
