METHODS AND COMPOSITIONS OF IMPROVING WELLBORE CLEANOUT TREATMENTS

摘要

Methods of performing a cleanout treatment including providing a wellbore in a subterranean formation having unconsolidated particulates therein; providing a treatment fluid comprising an aqueous base fluid and a hydrophobically modified flocculating water-soluble polymer; introducing the treatment fluid into the wellbore in the subterranean formation; flocculating at least a portion of the unconsolidated particulates by exposure to the hydrophobically modified flocculating water-soluble polymer; removing the treatment fluid comprising the flocculated unconsolidated particulates from the wellbore in the subterranean formation.
