A NEW MODEL FOR PRODUCED WATER TREATMENT IN ELEMIR OIL FIELD
The oil reservoirs of the southeastern part of the Panonian basin are characterized by considerablepresence of water,i.e.waterdrive. The hydrocarbon reservoirs are mostly in the middle and finalproduction stages. The water production is especially significant in wells producing with an installedElectrical Submersible Pump (ESP). As production continues, it is a realistic expectation that the watercut increases as well.The rapid production of water has affected fluid production in a significantway.Produced water in the Elemir oilfield is gathered, treated and then injected into the porous layersthrough several wells.The current system for the preparation and treatment of produced water in theElemir oilfield has functioned with evident technical issues.The main problems are increased volumesof produced fluids and the deposition of solids (scales) in water treatment system. In thisarticle, a newmodel for produced water treatment is presented, including technical, economic and environmentalaspects. A new model fulfils volumetric requirements, improves oil/water separation and suspendedsolids removal which lead to better injection performance.
