Physics-based analytics for plunger lift

Combine data and models for incisive well monitoring.

• Identify operational IPR: the well driving function
• Identify plunger slip coefficient (wear state)
• Identify plunger location and velocity
• Control plunger arrival velocity
• Identify cycle-by-cycle liquid production
• Identify when and how the well loads with liquid

Well control for plunger lift

Implement stable control that optimizes production.

• Different strategies appropriate for different wells
• Take advantage of well's strengths and avoid its weaknesses
• Minimize bottom-hole pressure over time
• Accommodate system upsets
• Minimize burden to field personnel
• Optimize maintenance
• Implement as an instrument or an RTU

Dynamic Pattern Recognition (DPR)

Identify a well operating state from the flow noises it makes.

• Gas flow
• Multiphase flow (all flow regimes)
• Plunger fall state
• Liquid and plunger arrival

Multiphase flow modeling

Quantitatively understand the flow dynamics responsible for well behaviors.

• Liquid and gas inflow and storage
• Transport of liquid and gas
• Effect of bottom-hole configuration on liquid intake
