PRODUCTION ENHANCEMENT SYSTEMS

Dewatering Production Unit

Among the main issues encountered with mature fields is the increase in water production which in many cases is not able to be handled by the production system and the flowlines resulting to significant increase in  backpressure imposed on the wells.

About the System

The SEP-iSYS™ Dewatering Production Unit (DPU) is a compact system designed to perform efficient oil water separation in order to be able to send only the crude oil to the processing facility, thus significantly reduced imposed backpressure caused by undersized flow-lines and processing system. This novel system consist of two vessels and a hydro-cyclone with the surge vessel upstream of the hydro-cyclone operating in batches, thus ensuring very stable flow to the hydro-cyclone.

This fully automated system is a compact, self-contained system with no external requirement and no rotating equipment allowing for easy installation and operation on unmanned well-head platforms. The system can also operate as a low pressure production unit when the well pressures decline as it can operate down to as low as atmospheric pressures.

Benefits

  • Perform oil-water separation on well head platform to reduce the flow into the production header and the processing system, thus reduces backpressures on the well

  • Allows optimum performance of hydro-cyclone by providing stable and fixed flow

  • Reduces the controls and instrumentation associated to the hydro-cyclone

  • Increases production and extends the lifespan of wells

  • No manning requirement

  • Compact, lightweight and cost effective making it suitable for unmanned remote wellhead platforms

Application

  • Onshore and offshore unmanned wellhead platforms
