Abstract
Hydrocyclone system for downhole oil-water separation provides an effective technique of enhancing the economic viability of higher water-cut wells while at the same time reducing the risk of environmental pollution. This paper describes the hydrodynamics of the liquid-liquid hydrocyclones and the flow fields within it are paramount for achieving successful separation process. Some of the important hydrodynamic flow phenomenon within the liquid-liquid hydrocyclone and how they influence the separation efficiency of water/oil was analyzed through analytical solution. The properties of the liquids were based on Bayan offshore field measured properties. The results indicated that there are two swirling zones separated by stagnant flow field. The inner is the light liquid zone, while the outer is the heavy liquid zone.
Highlights
The hydrocyclone nowadays finds many applications in the separation of solid–liquid streams, liquid– liquid streams and gas–liquid streams [1]

The mathematical models that describe the hydrodynamics of the LLHC and the flow patterns are presented. They were coded in excel spreadsheet taking into account the geometry of Fig. 1 and fluid properties similar to Bayan oil fields - Malaysia, to obtain information about the hydrodynamics and the flow fields likely to be observed in the course of using the LLHC
Summary
The hydrocyclone nowadays finds many applications in the separation of solid–liquid streams, liquid– liquid streams and gas–liquid streams [1]. Those that are used to separate suspended liquid droplets from another liquid stream are termed LLHC. LLHC can be employed downhole for the separation of oil-water products, due to its compactness, absence of moving parts and no chemical additives. This technology allows the produced water to be separated downhole and re-injected into the same formation at suitable depths. This paper presents the mathematical models that can be used to predict flow fields within LLHC and their influence on the separation performance of the system
