摘要

The present invention relates to fluids useful for treating injection wells to prevent or to reduce migration of particulates therein. Some embodiments of the present invention describe methods of introducing a tackifying treatment fluid through an injection well and into a portion of a subterranean formation surrounding the injection well, wherein the tackifying treatment fluid comprises a base fluid and a tackifying agent.
