Well Control Instrumentation

Advanced Choke Control SystemElectro-Flow Controls has been providing Well Control Instrumentation (WCI) to the global offshore drilling industry for more than 15 years. EFC's WCI has proved its worth on numerous occasions during well control incidents.

The WCI package is a real speciality of EFC, adding value to the Choke Control System of any rig. The family of systems can be integrated, combined or provided on a stand-alone basis.

The 2 key equipment elements comprise:

  • Finescale Gauges (FSG), large, high resolution analogue gauges displaying small scale pressure changes in the Standpipe and Choke & Kill Manifolds.
  • Liquid Seal Monitor (LSM), provides continuous indication of the integrity of the rig's Liquid Seal with an audible and visual alarm on loss/reduction of integrity.

EFC's additional Well Control Instrumentation systems include:

  • HPHT Monitoring Systems
  • Overboard Valve Controls
  • Choke Control
  • Advanced Choke Control Systems

Value Added Benefits include:

  • Increased operational safety
  • Cost-effective enhancement
  • Easily integrated into existing systems
