Deep Water Control System

Overview Library

SenTREE 3 well testing operations

The deep water control system (DWCS) provides fast-acting control of the SenTREE 3 subsea test tree for well testing operations performed from floating vessels.

Sequenced shut-ins

This combination of technologies performs a sequenced shut-in and unlatches from the landing string in as little as 15 seconds in water depths to 15,000 ft.

Applications

  • Well tests
  • Well cleanup operations

Benefits

  • Configuration flexibility to meet specific requirements without custom systems for each operation
  • Integration with any subsea system and BOP stack
  • Safety and reliability improvements through standardization of modular components
  • Reliable performance from proven technology, extensive testing, and 30-plus years of subsea experience
  • Support by Schlumberger personnel from program design to project completion
