Action buttons include:

Open

The Balanced notation at the top of the screen displays the status of the battery (Balanced or Not Balanced), including all products. If a product is Not Balanced, the battery status is also Not Balanced.

Balance Checks

When the battery is Not Balanced, a Balance Checks link is displayed to the right of Not Balanced at the top left of the screen.

Open

When the Balance Checks link is selected, all battery balance validations are executed again, and a window is displayed with the Balance Check Details.

• A green checkmark is shown beside validations that are successful.

• A red X is shown beside validations that failed.

• A simple box with a dash is shown beside validations that were not run due to a previous validation failing.

The following visual indicators and associated descriptions provide additional information to help to identify why the battery is not balanced:

• Battery Validation - Displays all the validations performed related to the battery in general.

• Battery Oil Production Validation - Displays all the validations performed when balancing the oil at the battery.

• Battery Gas Production Validation - Displays all the validations performed when balancing the gas at the battery.

• Battery Water Production Validation - Displays all the validations performed when balancing the water at the battery.

• Battery Gas Flow Production Validation - This section appears if the battery is attached to a gas flow control group, and it displays all the gas flow validations performed.

Open

Well Input

The Well Input tab of the Battery Balance is where well level data is entered or viewed. Each well can have data inputted manually and/or loaded by the FDC process. 

When you select the Well Input tab, the Well Theoretical Summary grid will appear. The data entered here is considered theoretical until Step 1 is run for the battery. 

Open

Well Theoretical Summary 

This grid displays the following information:  

• Wells attached to this battery.

• Well production totals (once entered and saved).

• By default, wells are displayed in Well ID order, but you can change sorting using the column header options.

  • There are two sort options available within the UWI column in the grid: one for UWI (default), and one for Petrinex UWI.

    • Sorting by Petrinex UWI will use the following sort criteria:

      • DLS Wells are sorted by Survey System, Meridian, Township, Range, Section, LSD, Event Sequence, Location Exception.

      • NTS Wells are sorted by Survey System, Map, Sub, Sheet, Block, Unit, Quarter, Event Sequence, Location Exception.

• Several column filters are available to shrink the well list displayed.

• Information is provided below the grid to show both the Number of Wells Attached to the Battery and the Number of Wells Acknowledged. Acknowledging a well means you have either entered monthly data or have shut it in.

To Select Wells to Shut In or to Clear Well Production:

1. Use the Select column to select well(s) using the checkbox on the far left of the grid.

Once wells are selected, the Shut In Well and Clear Well Production buttons are enabled.

Action buttons include: 

2. To view well production details, select anywhere in the row of the desired well.

Well Production Input

If data has not been entered for the well yet, this grid will automatically add one row for data entry. The Measurement Type of this row will default to the Measurement Type from the Well Master (Test or Measured). This default can be changed by selecting the Measurement Type drop-down.

Note: If the battery is using a Calculated Battery Gas Oil Ratio, then there will be an indication in the well heading (after the Well ID), as to whether the well is Eligible or Exempt.

1. Click the Create New button to add measured and/or test rows as required.

• To delete an extra row:

  • Use the Select box to select the row and then click the Delete button. 

  • You can also Select All and Deselect All rows.

Arrow keys (Up and Down) can be used to move between rows while remaining in the same column.

Carry Forward test entries allow only the Production Hours to be entered or modified. However, the ability to change any/all fields on such a test exists if you have enabled this functionality.

• For more information, see How To: Edit Carry Forward Well Tests. 

The Edit Test and Modified Reason columns are related to System Generated Carry Forward test entries. The Edit Test column will include a link that will launch a pop-up that will allow you to modify any field in the test.  This will only appear when the functionality has been enabled (as per the above link).  When a System Carry Forward test has been modified with this functionality, the reason entered for the modification will appear in the Modified Reason column.

2. You can Save or Save and Advance to Next Well once all required data for a well is entered. 

Edits

• Any Measurement Type

  • Input Gas cannot be greater than zero when the Well has a GOR associated with it.

  • Input Oil/Condensate, Input Gas, Input Water and Hours cannot all be zero.

  • Effluent Wells should not have any oil/condensate or water production entered, including Measured Wellhead Oil/Condensate.

  • Wells attached to a Battery using Prorate Water on Gas = Yes should have no water production entered and no water production being calculated based on a WGR.

• Measured Measurement Type

  • Input Oil/Condensate, Input Gas and Input Water all zero and Hours greater than zero only allowed when the well is Heavy Oil.

  • Input Oil/Condensate can be greater than zero when Hours are zero under the following circumstances:

    • Well is Heavy Oil.

    • Well is attached to a battery that has Prorate Measured Oil = Yes.

  • Input Gas can be greater than zero when Hours are zero in one of the following circumstances:

    • Well is Heavy Oil.   Note: Alberta and British Columbia do not currently allow Gas production with no Hours even on Heavy wells, so an Alert message will be generated during Step01 - Step02 processing as part of the data generation for the Petrinex Volumetric submission.

    • Well is attached to a battery that has Prorate Measured Gas = Yes.

  • Input Water can be greater than zero when Hours are zero in one of the following circumstances:

    • Well is Heavy Oil.

    • Well is attached to a battery that has Prorate Measured Water = Yes.

  • Effluent Wells should not have any Measured production; Test to Test only.

• Test To Test Measurement Type
  
  

  • Only allowed when the Well has a Measurement Type = TEST - Test To Test.

  • Hours cannot be zero unless the record is for a Carry Forward test.

  • Hours must be greater than Test Hours when not a Carry Forward test.

  • Input Gas cannot be greater than zero when the Well is attached to a Gas Measurement Exempt battery.
    
    

Measured Wellhead Oil/Condensate

Measured Wellhead Oil/Condensate can be entered just beneath the Production grid. This is used when the well is recombining oil/condensate into the gas, but some of the oil/condensate is being measured and disposed of directly.

Injection/Recovery (Optionally Displayed)

An Injection/Recovery section may be displayed under the Measured Wellhead Oil/Condensate field when the battery has been set up with Recovered Load Entry Method = By Well. This will allow for the entry of any unrecovered load oil or water that remains downhole at the end of the month. It is also possible (depending on setup) for the Unrecovered Load Oil/Water fields to be displayed but disabled.

• For more information, see Injection/Recovery of Load Fluid.
