Image Area Condition Monitoring of Subsea Equipment for Enhanced Equipment and Production Performance Tomi Entaban Sabah Oil & Gas Conference & Exhibition 26th May 2014
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 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, H 2 S, scale identification, conductivity Proven, accurate flow measurement of three-phase flow in all environments Introduction – Multiphase Flowmeters
6 15,000 psi rated: tested, approved and in operation 3500 m / 11,500 ft water depth rated 205º C / 400º F rated Introduction –Multiphase Flowmeters
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 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 Introduction – Subsea Boosting
9 Motor Section Pump Section ImpellerDiffuser Introduction – Subsea Boosting HELICO-AXIAL Pump design Oil submerged electric motor Integrated flow homogenizer
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 FRIEND ® Concept The availability of the FRIEND service has been 99.82 % since the startup in 2006 FRIEND has proven to be an important tool in pursuing a preventive maintenance philosophy and promoting collaboration with client personnel and experts
26 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
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 OneSubsea Alignment –Knowledge Base System –Equipment Reliability Classification –Further Footprint Analysis –Enhanced Condition Based Maintenance Cross-functional Decision-making Real-time Flow Assurance Management –Applications –Offline Studies –Reporting Summary
37 Main Goal: Increased Availability of the Equipment 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 !
