ABSTRACT:
A method is provided for reducing the corrosiveness of an aqueous fluid, particularly water containing dissolved oxygen and corrosive chemical agents such as naturally-occurring brine. According to the method, an enzyme which reacts with a substrate and consumes oxygen is added to the water along with a suitable substrate. Crude oil or other hydrocarbon material is also added to the water. The resulting water is less corrosive than water not containing the described system. In another embodiment of the invention, a water-flood method of post-primary oil recovery is provided in which the brine used is made less corrosive to metal drilling equipment by the addition to the water of an oxygen-consuming enzyme, a suitable substrate for the enzyme, and crude oil or other hydrocarbon material.
