Abstract
An elastomeric material that includes a silicon-based polymer can be positioned in a wellbore to provide fluid control with respect to the wellbore, such as by isolating a well interval of the wellbore. The elastomeric material can be formed using a mixture of a matrix polymer and a heterobifunctional siloxane polymer that can be incorporated into the matrix polymer. The elastomeric material can be positioned in a wellbore tool to form a seal in the wellbore.
Claims15
A mixture comprising:
- a polymer mixture comprising:
- a matrix polymer;
- and
- a heterobifunctional siloxane polymer comprising a set of siloxane monomers, wherein each siloxane monomer of the set of siloxane monomers comprises a first terminating group on a first end and a second terminating group different from the first terminating group on a second end;
- and
- a curing mixture combinable with the polymer mixture to incorporate the heterobifunctional siloxane polymer into the matrix polymer to form a modified elastomeric material positionable to form a seal in a wellbore tool that is positionable in a wellbore, the curing mixture comprising:
- a set of curing agents to cure the matrix polymer with the heterobifunctional siloxane polymer, wherein a first curing agent of the set of curing agents is combinable with the polymer mixture to form chain entanglements in the set of siloxane monomers and a second curing agent of the set of curing agents is combinable with the polymer mixture to form crosslinking of the matrix polymer.
