SVSA Integration Challenges

1
SVSA Integration Challenges

• On one typical platform there are
• Well Test Separator
• Gas Lift Manifold Valve Positioner
• Pressure Instrument
• RTD
• Turbine Meters
• Multi Variable Meters
• Downhole Gauges
• Multi-phase flow meters
• Pressure Instrument
• Electrical submersible pumps
• Data needs to be gathered and transmitted to main
  platform
• Remote control capability
• Minimize Cabling (high cost and logistics).
• Minimize use of solar panels (eliminate if
  possible)

SVSA Wireless Architecture is Critical for
Success

• Cluster Architecture
• On a single platform 18 monitoring units
  interfaced to various equipment creating a
  wireless mesh
• Data from platform is captured in a single
  Gateway which transmits data to main platform.

ADCO Objectives

• Prevent well shutdown which is impacting
  production by more than 7-10 annually.
• Real-time operation monitoring from the office is
  critical.
• Extending ESP life.
• Control of pumps is essential for production
  optimization and pump life.

ADCO Challenges

• Getting real-time data from high-value wells with
  Electrical Submersible pumps.
• Integration with existing well Pump surface
  systems.
• Wells are remote, distances are hundreds of
  Kilometers.
• Radio technology was not adequate for bringing
  data from such far locations.
• GPRS was a good option because of good coverage.

vMonitor ADCO Real-time Well Production
Monitoring and Control

• vMonitor deployed real-time ESP well monitoring
  using GPRS technology.
• Now wells can be monitored and controlled
  continuously.
• Problems can be predicted well in advance.
• Well shutdown can be reduced and even eliminated
