Abstract
A method of removing oxygen from a drilling fluid includes pumping the drilling fluid into a first inlet of a mixer, such that the drilling fluid is flowing in a first direction. Further the method includes pumping a gas including nitrogen into a second inlet of the mixer to mix the gas with the drilling fluid, the second inlet being downstream of the drilling fluid. The method includes flowing the gas in an opposite direction from the first direction, thereby permitting mass transfer of the oxygen from the drilling fluid to the gas to produce a deoxygenated drilling fluid; and discharging the deoxygenated drilling fluid from an outlet of the mixer.
