Downhole Oil/Water Separation System Effective in Horizontal Wells

The paper presents a system for separation of water in downhole horizontal wells in which the water produced from the well is not lifted to the surface but reinjected into the reservoir.

Examples of effect of total well production with downhole water separation. The left axis represents oil rates with/without separator, while the right axis represents the total liquid rate for the two same cases.

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.
