ESP Optimization

• Surveillance

Display operating point on performance envelope, trends for measured/calculated operating parameters and generate alert notification when value outside operating envelope

• Real-time measurements from SCADA
• Bottom-hole pressure, temperature, vibration
• Surface pressure, choke setting
• Frequency/speed, current, voltage
• Well Test / Production Allocation
• Liquid rate, GOR, water cut
• Surface fluid characteristics - oil, gas and water gravity
• Model computed values
• Gas Volume Fraction (GVF) at pump intake
• Motor winding temperature

• Diagnostics

Enable operations engineer to drilldown via engineering analyses and identify the cause of surveillance alert notifications and proactively take remedial action

• Examples
• Excessive gas at intake - adjust choke to lower production and increase flowing BHP
• Overheating motor - increase velocity past motor (shroud)

• Optimization
• Increase production - determine optimal speed through nodal analysis
• Extend pump life - maximize operation within the operating envelope
• Lower lifting cost
• operate within BEP region
• adjust operations so gas breakthrough in tubing occurs at a lower depth
• minimize choking
• debottleneck gathering system (network analysis)
