Produced Water Management Practices1. Prevent water from reaching the surface.2. Minimizing water production.3. Manage surface water.

Intelligent well completion (DOWS):

Oil is pumped to the surface. Water is injected back into formation.

2. Mechanical blocking devices: Duel completion Plugs Cement Polymer gels Packers Others

Final ThoughtsThe choice of produced water management method is site-specific.Large volumes of water is produced during oil and gas extraction. Current produced water management technologies are not sustainable. Produced water can be a valuable resource in water stressed regions.

recommendationsMore research is needed in the area of desalination and oilfield water treatment technologies to improve treatment of oilfield produced water for beneficial use.
