Tag Archives: Intervention Riser System. The system is integrated with a custom-fit subsea intervention lubricator (SIL) and is run using a deepwater umbilical with a pulling capacity of up to 20 tons. Intervention Riser System (IRS) This type of intervention unit has a surface BOP with a subsea emergency disconnect package (EDP) on top of the tree/wellhead connected via a riser. A dedicated riser system is not needed; the tree can be run on drill pipe. Intervention Riser System - exprogroup.org PDF Subsea Well Intervention The IRS enables access to subsea well trees while isolating the wellbore pressure as downhole tools like wireline or coiled tubing are deployed or changed out. Intervention access is possible with a mono-bore riser system, available as a rental package when required. The Intervention Riser System (IRS) will safely establish and maintain well access throughout riser to surface operations, replicating the functionality of the blow-out preventer and providing a . Our rigless intervention and stimulation offerings provide the same high levels of control and reliability as rig-based operations, with less mobilization time and cost. The project will require Expro to deliver an integrated subsea solution, including its industry-leading Intervention Riser System (IRS), to access the wells and undertake plug and abandonment work. The well intervention scope used Expro's integrated Open Water Intervention Riser System (OWIRS), deployed from the drillship Pacific Santa Ana for the intervention and barrier placement on 15 wells for PCMPL's Chinguetti Field Phase II works. Also in Australia, Expro has been commissioned to deliver an integrated program for a new subsea development. This method employs a marine riser with a drilling BOP and a subsea test tree to pressurize the well. The system's compact nature provided considerable time savings by retrieving the subsea trees without an . The 5 1/8" 10K IRS was required for a range of water depths covering all operations in the Central and Northern North Sea extending from 80m to 200m. The announcement for the 15,000-psi intervention riser system is one of the first steps we are taking on the road to become the pioneers in subsea well intervention." For further information, please visit www.subseaservicesalliance.com ### About Helix About Leader in the subsea well access space Expro signs four major subsea well access contracts in Australia and Malaysia. The intervention riser system, built and tested by Worldwide Oilfield Machines (WOM), is the largest of its kind operating in the Gulf of Mexico. Both systems are based on the Multi Purpose Tower which is responsible for all vertical movements of the equipment on board. To perform intervention/completion operations in open water mode, a riser system is required from the subsea well to the rig floor and a large surface equipment stack is required above the rig floor. The main riser sections are of pipe-in-pipe type construction with the outer pipe acting as a conductor. Both systems are based on the Multi Purpose Tower which is responsible for all vertical movements of the equipment on board. The Trident System, initially delivered in the Intervention Riser System (IRS) configuration, provides a 6-3/8" through bore and is suitable for all types of well intervention operations up to 15,000 psi and in water depths up to 10,000 ft. The MPT has the same functionality as a normal derrick but offers improved accessibility to the well . Subsea Intervention Systems: All Products Riser Systems-10K and 15K Riserless Systems - 10K and 15K 13 5/8-10K Wellhead / XT (H4 Connector) 13 5/8-15K Subsea Well Cap (Capping Stack) 6 3/8-15K Coil Cutting Valves 6 3/8-15K Deepwater Riser System (DRS) 6 3/8-15K Safety Head (Compact Cutting Device) 6 3/8-15K Surface Tree (Flow head) Riser-based intervention uses a high-pressure riser to contain the pressure during a workover or intervention operation. It can be configured for GE's latest Vetco Gray subsea tree systems in addition to legacy and other . Our Revolution PowerPlus In-Riser valve, launched in 2019, has all the attributes of the original technology but includes an integral accumulator power source within its housing to deliver super-fast closure and a failsafe solution below the BOP shear rams. Deployed from a mono-hull vessel, this wire through water system can be rapidly mobilized and deployed for all subsea well access requirements. Intervention Systems It currently enables access to both conventional vertical and horizontal subsea trees in up to 5,000' water depth, with the capability of the system being extended to 10,000'. Intervention (RWIS) technologies. Riser based operations can be performed by semi-submersible drill rigs or increasingly mono hull DP intervention vessels. The well intervention scope of the P&A project utilized Expro's integrated Open Water Intervention Riser System (OWIRS) for successful intervention and barrier placement on 15 wells for PCMPL's Chinguetti Field Phase II works. The well intervention scope of the P&A project, utilized Expro's integrated Open Water Intervention Riser System (OWIRS) for successful intervention and barrier placement on 15 wells for PCMPL . The WCP is a system of valves/rams utilized for well control purposes. The innovate system is designed, tested, and classed to DNV standards operational in water depths up to 1,500 meters in riser mode and 2,500m in riserless mode. GE Oil & Gas announced the introduction of a new Completion Work Over Riser (CWOR) system for its Well Access Intervention product line. Intervention riser system integrity needs to be established for both strength and fatigue performance. an intervention riser for an oil or gas well, which forms a connection between the well head and a floating surface vessel, is sufficiently flexible to accommodate the relative vertical movement. The Siem Helix 2 is an advanced well intervention vessel capable of completing a wide range of subsea projects Intervention Riser System (IRS) Wireline intervention, production logging, coiled-tubing operations, well stimulation and full plug and abandonment operations. Intervention Riser System for CT Deployment • As water depth increases, the cost of intervention increases. Our fully integrated LWI systems offer the industry's broadest functionality, resulting from extensive field experience and post-deployment analysis. Our rigless intervention and stimulation offerings provide the same high levels of control and reliability as rig-based operations, with less mobilization time and cost. Riser System Enabling efficient operations by reducing interface complexities and minimizes operational risk. Completion & intervention horizontal tree systems; Completion & intervention vertical tree systems; Control systems; Technology, design and certification; Award Winning Next Generation Landing String; Intervention Riser System; Riserless Well Intervention System; Light Well Intervention Vessel; Well Intervention and Integrity. International oilfield services company Expro has successfully completed an integrated Plug and Abandonment (P&A) contract worth more than $20 million for PC Mauritania 1 Pty Ltd (PCMPL), a subsidiary of PETRONAS.The well intervention scope of the P&A project in Mauritania, West Africa, utilised Expro's integrated Open Water Intervention Riser System (OWIRS), which was deployed from the .
