Title:
ELECTROCHEMICAL METHODS OF REMOVING DISSOLVED OXYGEN FROM DRILLING OR COMPLETION FLUIDS
Document Type and Number:
WIPO Patent Application WO/2019/055602
Kind Code:
A3
Abstract:
A method of treating a fluid in a subterranean formation comprises injecting a fluid into the subterranean formation, the fluid containing dissolved oxygen; contacting the fluid with an oxygen removal device, the oxygen removal device comprising an anode, a cathode comprising metallic nanoparticles loaded on a support, an ion exchange membrane disposed between, and electrically separating the anode and the cathode, and a power source electrically coupled to the anode and the cathode; and reducing the amount of the dissolved oxygen in the fluid.
