  • POLYMERIC COMPOSITIONS FOR DOWNHOLE APPLICATIONS
    Publication number: 20160032169
    Abstract: Methods for treating a wellbore and compositions used for same are provided that include emplacing a polymer-forming composition in the wellbore, and initiating polymerization of the polymer-forming composition to form a polymerized material in the selected region of the wellbore. In some aspects, polymeric compositions provided may also be useful for isolating pressure differentials downhole.

  • COMPOSITION OF POLYBUTADIENE-BASED FORMULA FOR DOWNHOLE APPLICATIONS
    Publication number: 20140305646
    Abstract: A method of treating a wellbore may include emplacing in at least a selected region of the wellbore a formulation that includes at least one diene pre-polymer; at least one reactive diluent; at least one inert diluent comprising an oleaginous liquid or a mutual solvent; and at least one initiator; and initiating polymerization of the at least one diene pre-polymer and the at least one reactive diluent to form a composite material in the selected region of the wellbore.
