Optimize well performance with electric completions
talk to an expertThe Volta™ all-electric control system is Halliburton’s most advanced SmartWell® intelligent completion solution. It delivers precise bi-directional zonal control, real-time reservoir management, continuous health and condition monitoring, and long-term reliability without hydraulic infrastructure. By replacing traditional hydraulics with electromechanical actuation, the system helps operators reduce complexity, lower emissions, and improve operational efficiency across multi-zone wells.
This solution combines electrification, intelligence, and reliability in one streamlined design. It delivers faster actuation, proactive health monitoring, and seamless integration with subsea architecture to help you maximize uptime and minimize intervention risk.
The Volta all-electric control system brings efficiency and flexibility to completions. Its hydraulic-free design simplifies installation and logistics, helping operators reduce both well OPEX and CAPEX. The standardized configuration provides multi-zone flexibility, making it easier to adapt to changing reservoir conditions.
It provides real-time reservoir optimization through bidirectional flow control, which helps keep production uninterrupted. Advanced condition monitoring improves well integrity by detecting early-stage scale build-up and addressing flow assurance issues before they become critical.
Electrification also reduces CO₂ emissions, supporting a more sustainable approach to operations. It features the field-proven HS-ICV valve, which has more than 2,000 deployments worldwide, giving operators confidence and reliability in every project.
At the core of the system is a single tubing-encapsulated conductor (TEC) line paired with a smart downhole network. This integrated design monitors, controls, and actuates the entire completion, delivering precise, real-time performance management across every stage.
Electromechanical actuation uses position sensors to deliver near-instant choke adjustments for accurate flow control. Bidirectional capability allows dynamic management of production and injection rates without shutting in the valve. Integrated pressure and temperature gauges provide real-time digital surveillance, helping operators manage water and gas breakthrough at the zonal level.
The system is compatible with any SmartWell® intelligent completion installation, including:
Subsea and dry tree wells
Extended reach and multilateral wells
Water-associated gas applications
Its proven reliability and flexibility make it ideal for challenging reservoir conditions and large step-outs where operational efficiency and uptime are critical, minimizing operational risks.
