Produced water quality has become an increasingly large area of concern for the oil production industry. Production facilities have been re-evaluating their conventional approaches to oil removal from water due to increasing water cuts caused by the maturation of their oil wells as well as a need for cleaner water for re-injection or disposal purposes. As such, the main concerns for produc- ers are that not only do many facilities require an upgrade to their existing equipment to handle higher capacities, but also that their facilities require a more rigorous and reliable system to maintain their water quality for re-injection or disposal specifications. Sigma delivers simple and economic systems for an efficient oil/water separation with complete process containment.
