  3. Introduction

  4. Introduction – Multiphase Flowmeters Well / production monitoring Production optimization • Gas lift and ESP Allocation metering Flow Assurance Immediate detection of water/gas breakthrough Calibration of reservoir models Material balance Mapping remaining reserves Reservoir monitoring • Water/gas breakthrough Introduction –Multiphase Flowmeters

  5. Introduction – Multiphase Flowmeters Introduction –Multiphase Flowmeters • OneSubsea™ has a focused and proven portfolio of subsea multiphase meters and measurement systems: • PhaseWatcher Subsea Multiphase and Wet Gas Flow Meter • Subsea sampling • Additional measurements: sand burst rate, H2S, scale identification, conductivity • Proven, accurate flow measurement of three-phase flow in all environments

  6. Introduction – Multiphase Flowmeters Introduction –Multiphase Flowmeters • 15,000 psi rated: tested, approved and in operation • 3500 m / 11,500 ft water depth rated • 205º C / 400º F rated

  7. Introduction – Subsea Boosting Enables production from remote locations/deepwater fields Kick off dead wells Accelerate production and extend production plateau Increase recovery by lowering well head pressure Overcome static height and header frictional losses Stabilize flow conditions in flowlines Combine high and low pressure reservoir in single flowline Flexibility and ease of installation and operation Introduction – Subsea Boosting

  8. Introduction – Subsea Boosting Introduction – Subsea Boosting • Up to 300,000 bpd (~ 2000 m3/hr) • Differential pressure 30 – 200 bar (~3000 psi) • GVF up to 95% (0-100% Mechanical) • Pressure rating up to 13,500psi • Water depth to 3000m • Shaft power rating 300 – 3000 kW • Height ~ 5m • Weight 7 – 20 metric tons • < 4m2 foot print

  9. Introduction – Subsea Boosting Introduction – Subsea Boosting Motor Section Pump Section • HELICO-AXIAL Pump design • Oil submerged electric motor • Integrated flow homogenizer Impeller Diffuser

  10. FRIEND® Concept

  11. FRIEND®Concept - Objectives • Facilitate 24/7 Remote Expert Assistance • Increase Equipment availability • Improve Lifespan of Subsea Equipment • Support Intervention Campaigns • Improve Communication and Collaboration w/ Operators • Enhance production performance FRIEND® Concept

  12. FRIEND®Concept - Services FRIEND® Concept TM 24/7 Support Portal with online tools Alarms and notifications Condition Monitoring Performance Monitoring Updated documentation Expert reporting Product improvement

  13. FRIEND®Concept - Data Collection FRIEND® Concept

  14. FRIEND® Concept - Monitored Equipment Pumps & Subsea Process Systems 17 |12 more on the way Multiphase Metering Systems 84 | 33 more on the way Swivels & Marine Systems 2 | 2 more on the way Subsea Trees & Production Systems New service offering!

  15. FRIEND®Concept - Statistics The availability of the FRIEND service has been 99.82 % since the startup in 2006 FRIEND® Concept FRIEND has proven to be an important tool in pursuing a preventive maintenance philosophy and promoting collaboration with client personnel and experts

  20. FRIEND®Concept – Vx Dashboard FRIEND® Concept

  21. FRIEND®Concept – Vx Solution Triangle FRIEND® Concept

  22. FRIEND®Concept – Vx OPI FRIEND® Concept

  23. Monitoring Methodology

  24. Monitoring Methodology FRIEND® Monitoring Methodology OneSubsea

  25. Operational Experience

  26. Operational Experience Operational Experience • Excellent relationship with client, OneSubsea always updated. • Planned maintenance/upgrade of equipment done in minimum time. • Reduced operating and maintenance costs. • Optimal use of the equipment (configuration).

  27. Operational Experience - Corrective Sequence Operational Experience Observation High variations in both suction pressure and pump power consumption Action Recommended the Customer to open the recirculation choke

  28. Operational Experience - Corrective Sequence Operational Experience Observation A drop in barrier pressure during a flowline pressure test caused negative seal dP towards process Action Called the Operators, and recommended bleeding off the flowline pressure

  29. Operational Experience - Corrective Sequence Operational Experience Observation Diverging temperature readings from two neighbouring transmitters, which if left unattended will reach HH and trip the pump in 2-3 months Action Inform Customer & Agree on Solutions

  30. FRIEND® Applications

  31. FRIEND®Applications - Trending Tools FRIEND® Applications

  32. FRIEND®Applications - Equipment Operational Envelope FRIEND® Applications

  33. FRIEND®Applications - Operational Performance Indicator (OPI) Monitoring operational health. Highlight information to identify suboptimal conditions. Status indicators for continuous operational improvement. Metrics to measure performance. Utilize expert experience. FRIEND® Applications

  34. FRIEND®Applications - Monthly Status Report / Review Status of the delivered equipment, as seen from an equipment vendor’s perspective. Evaluation of condition and performance Recommendations / Areas of Concern Actual data from the field used as input List of ongoing work (reports, studies, status of ongoing work orders, repair jobs, site work) Commercial details (progress reporting on open PO’s) FRIEND® Applications

  35. The Way Forward • OneSubseaAlignment • Knowledge Base System • Equipment ReliabilityClassification • FurtherFootprint Analysis • EnhancedConditionBasedMaintenance • Cross-functionalDecision-making • Real-time Flow Assurance Management • Applications • Offline Studies • Reporting Summary

  36. Summary

  37. Summary Summary • 7 years experience with real-time data • We perform equipment integrity monitoring and performance evaluation • Real-time data allows for effective 24/7 proactive service approach • This integrated working methodology has greatly improved the working relationship with Customer ! Main Goal: Increased Availability of the Equipment
