Abstract

Example methods and systems for segregation and treatment of waste water streams for enhanced oil recovery are disclosed. One example method includes generating concentrated solution by treating, using a forward osmosis process, waste water of one or more gas streams from a gas plant associated with one or more gas wells, where draw solution of the forward osmosis process includes produced water from one or more crude oil production traps, and the waste water contains kinetic hydrate inhibitor (KHI). The concentrated solution is treated using an oxidation process to generate oxidized solution by decomposing the KHI in the waste water. The oxidized solution is injected into an oil reservoir through a water injection well for enhanced oil recovery.
