Expro, the international oilfield services company, has expanded its subsea intervention capabilities, introducing two new well access solutions in addition to its established subsea landing string system technologies.
The Intervention Riser System (IRS), pictured above, will establish and maintain well access throughout riser to surface operations, replicating the functionality of the blow-out preventer and providing a safe and reliable means of well control, connected directly to the production tree. With increased coil tubing cutting and disconnect capability, the IRS system provides an alternative dual barrier, through-tubing system.
Expro's new RWI system
The new Riserless Well Intervention (RWI) system provides a wire through-water integrated solution for carrying out cost effective intervention and/or abandonment operations on all types of subsea wells. With a dedicated intervention vessel, all operating, deployment and retrieval efficiencies can be delivered safely and efficiently to clients.
These solutions add to the company’s existing subsea offering, which also includes Subsea Test Tree Assembly (SSTTA) solutions, which form part of a subsea landing string.
Expro’s latest development to the SSTTA is the Next Generation Landing String (NGLS), designed to fully comply with all aspects of the industry’s new API17G standard. It features a range of new functionality across its 7 3/8 valves, including high debris tolerant ball mechanism and hydraulic latch mechanism, and dual seal protection to both environment and control systems.
