ABSTRACT  Full text (pdf)

The oil reservoirs of the southeastern part of the Panonian basin are characterized by considerable presence of water,i.e.waterdrive. The hydrocarbon reservoirs are mostly in the middle and final production stages. The water production is especially significant in wells producing with an installed Electrical Submersible Pump (ESP). As production continues, it is a realistic expectation that the water cut increases as well.The rapid production of water has affected fluid production in a significant way.Produced water in the Elemir oilfield is gathered, treated and then injected into the porous layers through several wells.The current system for the preparation and treatment of produced water in the Elemir oilfield has functioned with evident technical issues.The main problems are increased volumes of produced fluids and the deposition of solids (scales) in water treatment system. In thisarticle, a new model for produced water treatment is presented, including technical, economic and environmental aspects. A new model fulfils volumetric requirements, improves oil/water separation and suspended solids removal which lead to better injection performance. 
Key words: Elemir oilfield, produced water treatment, scaling tendency, scale inhibition
