Well Access System

At 4Subsea we have leveraged our extensive expertise in subsea control systems and well intervention to provide an innovative solution that simplify well access and enhance oil recovery.

Revolutionizing Well Access

We are pioneering the development of the next-generation Electric Hydraulic Distribution Module (EHDM), a breakthrough in electric control for hydraulic XTs.

Our cutting-edge EHDM technology ensures safer, more efficient XT control during both intervention operations and production. It minimizes the size and footprint of rig equipment, boosts operational safety, and significantly cuts costs.

Key benefits

Choosing 4Subsea means investing in cost-effective, efficient, and sustainable solutions for your well access and oil recovery needs. Our technology not only reduces the cost of future tie-backs but also enhances control and operational safety.

By eliminating the need for hydraulic umbilicals and enabling the re-use of existing hydraulic XTs, we provide a forward-thinking approach that supports both current and future field operations.

  • Simplified Well Access: Our solutions streamline well intervention, completion, and plug & abandonment (P&A) processes.
  • Reduced Equipment Footprint: By eliminating the need for a hydraulic umbilical, we drastically reduce the weight and footprint of rig equipment.
  • Enhanced Efficiency: The electric tie-back of hydraulic XTs eliminates the need for costly hydraulic umbilicals, reducing subsea tie-back costs and improving XT control.
  • Battery-Powered Operations: Our system supports battery-powered operation, removing the need for power cables from the rig.
  • Future-Proof Technology: We are developing new generation hydraulic control pods for electrical XTs, ideal for all-electric fields of the future.
