Abstract
The present embodiments generally relate to methods and compositions comprising one or more polymers which gradually increase in charge, thereby providing for an increase in viscosity in an aqueous solution or aqueous composition, such as when present in a desired aqueous environment. Use of such compositions and methods comprising one or more polymers which gradually increase in charge, thereby providing for an increase in viscosity in an aqueous solution or aqueous composition during enhanced oil recovery may result in an increase in oil production relative to methods and/or compositions which do not comprise one or more polymers which gradually increase in charge, thereby providing for an increase in viscosity in an aqueous solution or aqueous composition.
