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
