dc.description.abstract Production management of produced water has become a major issue of hydrocarbon production, since the produced water increases as the field grows older and the cost of water handling, such as separation, treatment and repair is dramatically increasing. Management of produced water presents challenges and costs to operators. If the entire process of lifting, treating, and re-injecting can be avoided, costs and environmental impacts are likely to be reduced. With this idea in mind, during the 1990s, downhole separation emerged, in which the oil or gas rich stream is produced to the surface, while the water-rich stream is injected to an underground formation without ever being lifted to the surface or it can be produced separately to the surface. These devices are known as downhole oil/water separators (DOWS) and downhole gas/water separators (DGWS). Liquid-Liquid Hydro-Cyclones is an integral part of a down-hole oil water separation system. Despite performance and functionality of cyclones not being fully understood, they have created new ways for separating fluid down-hole for the producing formation and injecting separated water far away from the production interval. This study provides a full description of downhole separation technology, showing the types, advantages, requirements and limitations of the technology. The report also provides data on a wide range of field trails and from different locations. Computational Fluid Dynamic (CFD) was used to understand the behavior of the liquid-liquid hydro-cyclone in downhole conditions. It was also used to simulate the applicability and efficiency of separation using Liquid-Liquid Hydro-Cyclones in Well-04 in Heglig field in Sudan. en_US
