Abstract
A method and system for treating a water stream which contains Fouling Organics, where the water stream is recovered from an underground hydrocarbon-containing formation during SAGD oil recovery operations conducted on said formation. The method comprises injecting an oxidizing agent, preferably air, into the water stream when first recovered from the underground formation, and using a porous membrane to separate oxidized Fouling Organics and/or filter separable compounds formed due to injection of the oxidizing agent into the water stream, prior to transferring the water stream to a boiler for re-heating the water stream and turning same to steam for re-injection into said formation.
