  14. Pump-Off Control • Maximizes ProductionWhile Minimizing Cost • Saves Lost ProductionDue to Frequent Workovers • Reduces Wear on Rod String, Pump and Gear Box • Fewer Pump Strokes Per Day • Protects Against Rod Parts Damage • Caused by Fluid Pound • Saves Energy Costs by Not Operating Partly Filled Pump • Protects From Gas Locking • Increases the Economic Life of Stripper Wells • Available as application using • Stand Alone Unit, as 6400 or 6700 Series Flow Computers or 6790 RTU-PLC

  15. Plunger Lift Plug-In RTU Performs: Plunger Lift Application and Valve Control Flow Computer Monitoring: Differential Pressure Line Pressure Computing Flow Rate Tubing Transmitter Control Valve Plunger Arrival Sensor • Increases gas production by keeping liquids off the formation • Generally speaking, used on wells that do not have enough constant downhole pressure to free flow into a gathering system • General Scheme • Steel Plunger is inserted into the production tubing • Shut-in causes plunger to fall allowing fluid to collect above plunger • Different methods used to decide how long to shut-in and flow well • Downhole pressure is used to life the plunger and fluid to surface • Adaptive algorithms make adjustments in order to optimize plunger rise time.

  16. Valve Controller Options • Digital controller • Uses two digital outputs to control direction of valve • Uses two digital inputs to detect full open and closed position • Only consumes current when moving valve • Analog controller • Uses one analog output to open and close valve • Uses two digital inputs to detect full open and closed position • Interfaces to standard I/P converters

  17. Differential Pressure Static Pressure Flow Rate Differential Pressure Overrides (High & Low) On/Off Timer and/or Pressure Operation Pressure Override Nominations Valve Control Modes

  18. Intermitter Controller Features Optional Timer Mode: On Time = Hours:Minutes Off Time = Hours:Minutes 6713 Flow Computer Optional Pressure Transmitter 100% 100% Restart Set-Point DP Low Limit 0% 0% Valve will shut-in after delay time Valve will open (Start control, Nominations etc.)

  19. Pressure Override Feature • Programmable pressure override limit • Override can cause valve to fail close • Programmable pressure restart value if valve is closed • Typical Application: Automatic Well shut-in ifcompressor goes down. Auto restart well when compressor is repaired 6713 Flow Computer Pressure Transmitter Control Valve Compressor

  20. Nomination Features • Flow Nomination Target Volume • Selectable Start and Stop Date • Monitors and Adjusts Valve Automatically to Insure Correct Volume Deliveries • Works in Conjunction with other On/Off Control

  21. Nomination CCU Setup

  22. Proportional Sampling on Flow Computer • Two Digital Outputs available to provide a signal to sampler(s) • User enters a volume set point in MCF • Output energizes for 5 seconds then resets (Standard 12 VDC, Optional contact closure)

  23. Kansas Deliverability Test (KDT) • Automatically conduct periodic Kansas State Deliverability Test on either a single or a Group of Wells. • Record data entered manually and/or automatically • Report Data From Test

  24. Pressure Buildup Test • Used in conjunction with Valve Control • Automatic Well Shut-in • User specified time period for test • Record increases in pressure after shut-in • Used by reservoir engineers
