Notes:
1. Remote Flow Calculations
1.1. PMWO supports using Flow Calculations from a remote device. They must be stored in a
Softpoint in the following order for PMWO to be able to access all of the values it needs.
1.1.1. Data 1 = DP
1.1.2. Data 2 = Pressure
1.1.3. Data 3 = Temperature
1.1.4. Data 4 = Instantaneous Daily Rate
1.1.5. Data 5 =Accumulated Flow Today
1.1.6. Data 6 =Accumulated Flow Previous Day
1.1.7. Data 7 =Accumulated Flow Month
1.1.8. Data 8 =Accumulated Flow Previous Month
1.1.9. Data 9 =Running Accumulator
1.2. When pointing the Point Definition of a configurable Flow to a Softpoint:
1.2.1. If Rate is selected PMWO will automatically select Data Register 4
1.2.2. If Accumulator is selected PMWO will automatically select Data Register 9
2. Many Point Definition fields will auto‐select the appropriate parameter
2.1. When browsing for AGA meters, select the AGA Type either Orifice or Linear and the correct
Logical Number and PMWO will select the appropriate Parameter.
2.2. When browsing for PID Loops, select the correct logical number and PMWO will select the
appropriate Parameter.
2.3. When selecting Discrete Outputs on the GAPL configuration
2.3.1. If the DO’s Auto Output is selected only One DO can be configured. It is assumed a single
DO opens and closes the GAPL valve.
2.3.2. If the DO’s Momentary Mode is selected a second DO is made available to use for pulse
open and pulse close operation.
3. Well TLP Update Rate
3.1. All calculations and values that must be stored to insure proper boot up without losing
resolution are done every second.
3.2. But in an effort to drastically reduce MPU loading, monitored only parameters are only written
to TLPs based on this setting. The default is 5 seconds. Increasing this time does not affect the
operation of the well, only slows down the updating of monitored values.
4. Insufficient Configuration Error
4.1. This is based on minimum configuration requirements and the type of Gas Lift being used.
4.1.1. Minimum Requirements and Gas only Optimization
4.1.1.1. Production/Sales Meter
4.1.1.2. Injection Meter
4.1.1.3. Injection PID
4.1.2. Maximum Hydrocarbon or Max Revenue
4.1.2.1. Minimum plus Hydrocarbon Meter (or Tank Manager Accumulators)
4.1.2.2. Water recommended for Total Revenue calculation
4.1.3. Maximum Water
4.1.3.1. Minimum Plus Water Meter (or Tank Manager Accumulator)
5. Non‐Optimizing Wells
5.1. Configure Core only and use PM Surface Controls (PMSC) to manage shutdowns
6. PM Auto‐Choke Controlled Wells
6.1. Configure Core only and use PM Surface Controls (PMSC) to manage shutdowns
7. Plunger Assisted Gas Lift (PAGL)
7.1. Defined as: A gas lift well with a plunger to assist with lifting liquids
7.2. Enable Gas Lift and Cyclic on the same instance
7.2.1. Define Cyclic type as Continuous Plunger
7.2.1.1. Define Triggers to run the Continuous Plunger
7.2.2. Configure the Valve Closure and Abort Testing
7.2.2.1. Set the Max Production Closed Minutes greater than the amount of
time the production valve is closed to send the Continuous Plunger back down the
well.
8. Gas Assisted Plunger Lift (GAPL)
8.1. Defined as: A plunger lift well with gas assist to bring the plunger up
8.2. Enable GAPL as one of the options for the Plunger Type
8.2.1. Configure the GAPL Flow Meter
8.2.2. Configure the GAPL Control Valve
8.2.2.1. PID
8.2.2.2. DO (Single or Dual see 2.3)
8.2.3. Define when to use and open the GAPL valve
9. Venting
9.1. Venting is still supported in this version in the same method as in the past.
10. Offset Gain Factor is a new function that will automatically adjust the amount of Injection Setpoint
change at the end of an averaging cycle. It monitors the “Improvement” amount for each averaging
cycle and if the amount of improvement is less than the Max Step Change amount, it will adjust the
Injection Setpoint +/‐ the Improvement * Offset Gain Factor. This will allow smaller step changes to
the injection amount as the well gets closer to steady state operation.
11. Gas Lift Valve Sequencing Auto‐Run is a new feature that allows the operator to select an amount of
time to allow the well to be down and when exceeded will automatically restart the well using the
parameters of the Gas Lift Valve Sequencing function. Allows exercising of the mandrel valves down
hole if the well has been down for too long.
