MODIFICATEURS DE LA PERMÉABILITÉ RELATIVE MODIFIÉS PAR VOIES HYDROPHOBE ET CATIONIQUE ET PROCÉDÉS ASSOCIÉS

摘要

Methods comprising introducing a hydrophobically and cationically modified relative permeability modifier into a portion of a subterranean formation. The hydrophobically and cationically modified relative permeability modifier comprises a hydrophilic polymer backbone with a hydrophobic modification and a cationic modification. The cationic modification may comprise at least one cationic compound comprising an alkyl chain length of from 1 to 3 carbons.
