  • Hybrid cement set-on-command compositions
    Patent number: 9441147
    Abstract: The present invention relates to methods and compositions useful for isolating a portion of a wellbore. In one embodiment, a method includes preparing a sealant composition containing two phases. The sealant composition is placed into the wellbore where one phase sets upon subjecting the sealant composition to a thermal source followed by the setting of the other phase.
    Type: Grant

  • Hybrid cement set-on-command compositions and methods of use
    Patent number: 8770291
    Abstract: A method for isolating a portion of a wellbore including preparing a sealant composition includes an emulsion of an internal phase and an external phase. The sealant composition is placed into the wellbore where one phase sets upon subjecting the sealant composition to a thermal source followed by the setting of the other phase.

  • ELECTROLYTE
    Publication number: 20110189579
    Abstract: An electrolyte includes a continuous meso- or nanoporous component and a polymer electrolyte phase having a conductive matrix or continuous conducting component. The continuous meso- or nanoporous component includes an interconnected porous structure and may, for example, be a monolith. When the porous component is contacted with the electrolyte phase, the porous component is filled with and integrated into the electrolyte phase.
