Automation totalflow measurement control systems example applications

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

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.


Valve controller options

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

Pressure override feature

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

Nomination features

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


Nomination ccu setup

Nomination CCU Setup


Proportional sampling on flow computer

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)


Kansas deliverability test kdt

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


Pressure buildup test

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
