This paper describes the production chemistry management process undertaken during the design, commissioning and start-up phases of the Schoonebeek redevelopment. Challenging separation issues, saline water, together with a multitude of other process conditions, resulted in complex, but robust application portfolio. This was established during the design stages of the project. Early involvement of the production chemistry discipline aided this process. Chemical selection was conducted in adherence to HSSE directives and focusing on unique produced fluid properties. Since start-up, the success of chemical performance has been due to the availability of chemical treatment programs and surveillance/sampling plans. No contingency chemicals have so far been needed at the facilities since start-up. Export oil and water key performance indicators have been for the majority of the time met. Further optimization of chemical applications is an ongoing process which will follow the life of the field.
