The complete paper focuses on a system for water separation in downhole horizontal wells. The water produced from the well is not lifted to the surface, but reinjected into suitable parts of the reservoir, either for pressure support or for diposal. The method of water separation and reinjection has been evaluated for oil-producing fields. The complete paper presents details of the technical solutions and an economic analysis.
Introduction
The concept of downhole oil/water separation (DOWS) has been oriented around hydrocyclone-based technologies.
