Hydrocyclone technology has been successfully applied to standard oilfield production separation in the North Cowden Deep Field of West Texas. A hydrocyclone was successfully tested as the primary means of water separation for a high water cut electric submersible pump (ESP) well, thereby eliminating the need for expanding the conventional water separation and handling facilities at the recipient battery. This hydrocyclone system was environmentally and economically preferred over conventional systems. A permanent unit has since been installed. With its feasibility proven, the hydrocyclone has countless applications to standard oilfield production separation; its proper use will substantially reduce capital investment for facilities and lower operating expenses for many oilfield leases.
