Low salinity reservoir environment

A method to enhance oil recovery from a hydrocarbon-containing formation, the method comprising:

• a. injecting a mixture of high salinity brine and low salinity brine into the formation, wherein the mixture is injected into the formation through a first pump, wherein the first pump is a automated control pump, wherein the mixture is injected at a flow rate based on the physical characteristics of the formation, wherein the flow rate of the mixture gradually and continuously decreases, wherein the flow rate of the mixture gradually and continuously decreases the concentration within the formation;
• b. simultaneously with step(a), injecting fresh water into the formation, wherein the mixture is injected into the formation through a second pump, wherein the second pump is an automated control pump, wherein the fresh water is injected into the formation at a flow rate based on the physical characteristics of the formation, wherein the flow rate gradually and continuously increases;
• and
• c. introducing surfactants and/or polymers into the formation, wherein the surfactant acts as a motive force to drive the hydrocarbons towards one or more production wells.
