Abstract: Systems and methods for using one or more electrolyzed aqueous solutions to treat subterranean reservoirs containing hydrocarbons are disclosed herein. In some cases, the methods include using an electrochemical cell to produce electrolyzed acidic water and electrolyzed alkaline water. In such cases, the electrolyzed acidic water or the electrolyzed alkaline water is introduced to the well. While the electrolyzed acidic or alkaline water can be used for a variety of purposes, in some cases, it is used to improve hydraulic fracturing, water flooding, and well stimulation techniques. In some cases, the electrolyzed acidic or alkaline water is mixed with one or more other materials, such as a proppant, a hydraulic fracturing fluid, a polymer, or another additive. Additional implementations are disclosed.
