AI Technical Summary

Benefits of technology

The patent is about using electrolyzed water to improve the recovery of oil from reservoirs. The system involves injecting electrolyzed water into a well and driving the oil from the reservoir to a production well, where it can be recovered. The invention has been found to enhance the effectiveness of oil recovery.

Problems solved by technology

While the aforementioned methods for treating subterranean reservoirs may be useful for enhancing hydrocarbon recovery, such methods are not necessarily without their shortcomings.

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.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 507,458, filed Jul. 13, 2011, entitled “Treatment of Hydrocarbon Containing Petroleum Reservoirs with Electrolyzed Water,” the entire disclosure of which is hereby incorporated by reference.FIELD OF THE INVENTION[0002]This invention relates to systems and methods for enhanced recovery of hydrocarbons from a hydrocarbon containing reservoir. More specifically, in some implementations, this invention relates to the use of electrolyzed water for hydraulic fracturing, water flooding, well stimulation, and other processes that can improve recovery of a hydrocarbon (such as a crude oil or natural gas) from the reservoir.BACKGROUND OF THE INVENTION[0003]Crude oil is the world's main source of hydrocarbons that are used as fuel and petrochemical feedstock. To enhance recovery of crude oil or other hydrocarbons from subterranean reservoirs, various methods for treating such ...
