S.W.I.S. surface water injection system

S.W.I.S. surface water injection system

Surface-driven converted centrifugal pump is used in pressure maintenance systems with low-pressure pipelines.


Separate water injection into discharge wells in reservoir pressure maintenance systems.


  • Installation within 1 RIH/POOH operation;
  • Pump and drive replacement without well killing;
  • Easy wide-range injection control;
  • Use of TMS data for injection control;
  • Safe tubing pressure release into annular space during workover;
  • Well killing and discharge equipment included;


  • Use of low pressure pipelines in reservoir pressure maintenance systems;
  • Specified geological parameters achieved through controlled injection;
  • Reduced maintenance and repair cost;
