DERIVATIZATION OF POLYMERS AND WELL TREATMENTS USING SAME |
摘要 |
Polymers are derivatized and then may be introduced into a wellbore, such as in a hydraulic fracturing treatment. A polymer may be a guar powder that is mixed with an organic solvent and derivatized using a derivatizing agent, such as sodium chloroacetate. The polymer is typically derivatized in bulk prior to introduction into the wellbore. The derivatized polymer may be hydrated and/or cross-linked prior to introduction into the wellbore.
