<p>A well treatment method includes drawing a solvent to a first pump (24), drawing a wetting liquid to a second pump (16), pumping the wetting liquid through a polymer mixer (20) using the second pump (16), combining polymer with the wetting liquid to produce a slurry containing undissolved polymer, and combining the slurry with the solvent upstream from the first pump (24). Another well treatment method includes increasing dissolution time of the polymer by providing a buffering agent (30) in the wetting liquid before combining the wetting liquid and the polymer. A well treatment system includes a polymer mixing subsystem with a mix loop having a mix loop inlet line from a first pump feed line and a mix loop outlet line back to the first pump feed line, the mix loop outlet line containing a polymer mixer (20).</p> |
