Customer’s Requirement
As exploration and development projects moved into deeper and deeper waters, there was a requirement to improve the valve and control systems on Subsea Landing Strings during well testing, completion and interventions. This was required to reduce the response times so that an emergency disconnect could be carried out within the time requirements of dynamic positioned drilling units. Shell needed a system for the commissioning of subsea wells in deep water off the coast of Egypt.
Expro’s solution
An electric hydraulic system which provides a safe and environmentally secure operating system for the Exploration and Appraisal applications. The Subsea EXPRESS E-H control system was used in conjunction with an ELSA – EA.
Results
Expro recently successfully completed the ultra deepwater job off the coast of Egypt using the ELSA E-H system. This was the first ultra deepwater test performed in North Africa. This was carried out in a water depth of 7,861ft, using a 10,000ft reel pack. The system response time was 10 seconds to close the valves and disconnect the subsea test tree (SSTT). The ELSA system and associated package was in the hole for 19 days without any operational issues and all of the operator’s objectives were met on this project.
Technologies used
Expro designed the industry’s first 10,000psi, 250°F-rated electro-hydraulic system to be used during exploration and appraisal applications. This system is used so that well operations can be carried out safely during the exploration and appraisal application in water depths up to 10,000ft.
