Prod Cums tab

 

The Prod Cums tab displays and modifies cumulative production values for the selected well on the well list.  To modify an entry, select the "Details" button.

Prod Cum data by itself isn't easily mappable or used in calculations.  It's often useful to use the Extract PdCum Data To Zone tool to copy some of these variables to a zone data item.

The ProdCums tab displays the selected well's cumulative production

Details

The PdCum Details Tool changes the data in an individual well and column names for the entire project.  This tool also deletes all production cums from the project.

Data tab

The Data tab changes individual data for a specific well.  This includes changing the formation name, top and base, dates, and production cums.

Fixed Column Labels

The Fixed Column tab changes the names of the columns as they appear on the Prod Cums tab.  Most users will want to leave these alone.

User Column Names

The User Column Names tab sets the column definitions for the user column names.  Here, select the desired column and change the name and type.  Note that numerical fields can have a set number of decimal places

Options

The Options tab sets options for:

  • Substitute FMNAME when ALTNAME is BLANK - Replaces missing entries for altnames with the formation name.

  • Date Format - Selects how Petra displays dates.  By default, Petra uses mm/dd/YYYY

Advanced tab

Performs additional maintenance tasks, including global PdCum deletion and locking wells.

  • Global Deletion - Deletes all PdCum entries with a set FmName.  Note that the name must match exactly.

  • Locks - Locks and unlocks the PdCum entries for the selected wells.

  • Set ZERO Top and Base Values to NULL - Replaces PdCum tops and bases with "0" values to a null.  This can be useful for eliminating erroneous calculations involving depths.

Report tab

The Report tab creates CSV file of PdCum data.

  • To add a data column to the report, double-click the desired data field in the "Available Columns" list.  

  • To remove a column, double-click the desired data field in the "Report Columns" list.

  • To rearrange the list in the Report Columns list, select the desired field, and use the up and down arrows to move the individual data field up or down.  Entries on the top of the list will appear first (and to the left) on the CSV.
