  • Patent number: 7886826
    Abstract: A method for treating a subterranean wellbore. More specifically, a method for removing wellbore solids. A first, polymer containing fluid is placed in the solids bed. A second, viscosifying fluid is then placed into the solids bed thereby agitating the solids in the bed and causing the formation of a gel capsules when mixed with the biopolymer fluid. These gel capsules are capable of trapping or entraining the agitated solids. The gel capsules typically have a relatively high volume and a relatively low density, thereby making their removal from the wellbore easier.
    Type: Grant
    Filed: April 23, 2010
    Date of Patent: February 15, 2011
    Assignee: Schlumberger Technology Corporation

  • Patent number: 7703529
    Abstract: Disclosed are methods of treating a producing well by removing wellbore solids. Accordingly, a first, polymer containing fluid is placed in the solids bed, and a second, viscosifying fluid is then placed into the solids bed thereby agitating the solids in the bed and causing the formation of a gel capsules when mixed with the biopolymer fluid. These gel capsules are capable of trapping or entraining the agitated solids. The gel capsules typically have a relatively high volume and a relatively low density, thereby making their removal from the wellbore easier.

  • Patent number: 7304019
    Abstract: Suspensions are provided of water-soluble materials in non-aqueous carrier fluids using suspension agents that include organophilic clays. Methods of forming such suspensions are provided. Methods are also provided for using such suspensions to prepare aqueous solutions, in particular thickened aqueous solutions, in particular for use in oilfield treatments.
