Well Access Systems
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.
Evolving Beyond Traditional WOCS Solutions
The offshore industry is moving away from conventional Workover Control Systems (WOCS), which require heavy, cumbersome topside equipment with a large footprint on rigs and vessels. Traditional systems also demand extensive management of large XT umbilicals, leading to operational complexities and increased safety risks.
Advantages of Transitioning to a Next-Generation Solution
- Reduced safety risks by minimizing red zone activities and personnel exposure
- Decreased equipment requirements and smaller operational footprint
- Simplified handling with smaller umbilicals
- Shorter rig and operation times, enhancing efficiency
- Lower personnel on board (POB) requirements
- Compatibility with multiple XT vendors and control fluids
- All the capabilities of an XT umbilical parking frame—with added advantages
Our solution supports a safer, more efficient, and versatile approach to workover operations, meeting the demands of modern offshore environments.
