15. A method for selectively optimizing water chemistry within a wellbore, the method comprising:
positioning a system tubing in the wellbore, the system tubing comprising an electrochemical cell, a first chamber, and a second chamber;
injecting a fluid into the electrochemical cell;
directing an electrical current into the electrochemical cell, wherein the fluid separates by charge into a first fluid and a second fluid;
passing the first fluid into the first chamber and the second fluid into the second chamber;
rotating the system tubing, wherein the first fluid flows from the first chamber to the wellbore though a first radial conduit and the second fluid flows from the second chamber to the wellbore through a second radial conduit.
