Method of controlling particulate flowback in subterranean wells and introducing treatment chemicals

摘要

A subterranean formation is treated with a particulate-laden fluid and a treatment chemical, whereby particulate flowback is reduced or prevented while also providing a controlled release of the treatment chemical within the formation. A fluid suspension including a mixture of a particulate, a tackifying compound and the treatment chemical, is pumped into the formation and depositing therein within whereby the tackifying compound retards release of said treatment chemical and also retards movement of at least a portion of the particulate within the formation upon flow of fluids from the subterranean formation.
