Abstract
Methods of treating a subterranean formation are described. The methods include introducing a treatment fluid that includes a friction reducing polymer (e.g., a cationic friction reducing polymer or an anionic friction reducing polymer) into the subterranean formation. The cationic friction reducing polymer is allowed to degrade and release choline chloride or polyDADMAC, which can each act as a clay stabilizer. The anionic friction reducing polymer is allowed to degrade and release AMPS, which can act as a surfactant, a scale inhibitor, a paraffin inhibitor, or an asphaltene inhibitor, or polyacrylic acid, which can act as a scale inhibitor.
