Abstract: Compositions for water treatment are provided. In some embodiments, the composition comprises: a cationic polyacrylamide-type polymer having a charge density of about 10% to about 40% and a molecular weight of about 600×104 g/gmol to about 900×104 g/gmol; and a cationic surfactant, the surfactant comprising an alkyl quaternary ammonium salt. Also provided are related methods and kits for treating wastewater with dispersed and dissolved organic matters and oils. Embodiments of the compositions, methods, and kits can be used to treat oil-in-water emulsions, produced water, and process water containing dispersed and/or dissolved organic matter such as hydrocarbons from various process industries including Steam Assisted Gravity Drainage (SAGD) oil operations.

Abstract: A method of monitoring a reservoir during an oil recovery process includes placing a plurality of electrodes proximate the reservoir, injecting a nanoparticle dispersion into the reservoir with an injection fluid, and recording a current measurement and a voltage measurement from the plurality of electrodes with an electronic control module during the oil recovery process.
