Expro Launches Solus™ – The Single Valve Solution For Subsea Well Access
Advanced equipment technology delivers one valve shear and seal on wire and coiled tubing.
Replacing the conventional requirement for two valves with just one, Solus™ revolutionizes the industry’s approach to subsea well access, reducing operational risk and complexity while accelerating the drive toward more cost-efficient subsea intervention technologies.
Tested and validated in accordance with API Std 17G, Solus™ is the first fully NACE MR0175 compliant fail- close bi-directional high-debris ball valve system that can shear and seal on wire and coiled tubing.
Expro’s Solus™ advanced equipment technology can be used in both in riser and open water applications across the entire well lifecycle - from exploration and appraisal and completion intervention to plug and abandonment (P&A) and decommissioning.
Solus™ has already been deployed for a new in-riser completions development in the Gulf of America and installed in an open water system for a North Sea P&A campaign. The system provides shear and post-shear seal for gas and liquids on slick line, braided electrical cable, and coiled tubing. It delivers bi-directional sealing for liquids and gas, even aſter a pump-through.
Solus™ has also been included in the Expro lightweight P&A Open Water Intervention Riser System (OWIRS). By achieving a Shear and Seal in a single valve, this technology allows Expro to introduce Solus into the open water application.
Solus™ modular design allows isolation and disconnection from the well. Its compact design and increased flexibility match the industry’s advance in next generation smaller-sized BOP (blowout preventer) stacks and enables more efficient supply chain management.
The system’s fail-close design reduces risk of emissions and provides a
unique well safety barrier. Expro’s world-class integration or ‘whole system’ experience provides user surety and confidence. Replacing a two-valve system with just one valve simplifies operations management.
Solus™ offers superior high debris (HD) flexibility for a wider range of complete well lifecycle challenges, with 15% solids ingress qualification size.
Solus™ is the latest technology from Expro that demonstrates the company’s innovation and expertise in systems integration, engineering excellence, and deep understanding of the industry’s needs. The system advances Expro’s 40-year legacy of leadership in the global subsea sector.
Solus™ is available in Expro’s ELSA landing string assemblies equipment offering. It is available in-riser as a single valve, a single valve with a latch mechanism, or within a subsea test tree, and within an OWIRS.
