Columns in the Ownership Table

These are the standard columns in the ownership table. Click on the icon on the top left or hide specific columns on the grid.

• Case ID – The ID Code ties each record to a case in PHDwin. New rows should be populated with the proper Case ID. This is a required field when adding new ownership records and tells the program which case the ownership or ownership adjustment will be applied to when the Grid Editor is closed.

• Case Name – Displays the case title so users can easily recognize it. While the system uses Case ID internally for linking, the case name helps identify and manage records. If a new ownership entry is created, filling this field is optional.

  • Sequence – Determines the order of ownership records. Starts from 1 for the initial entry and increases with each revision.

  • Reversion Type – Used to define the initial setup or any changes over time. Available types include Payout, Cumulative, or Date-based.

  • Product – Relevant only for cumulative reversions. Select the product that will influence ownership changes based on production volume.

  • Reversion Date – Mandatory for date-based reversions. Each entry should follow predefined or linked dates. Initial ownership is always aligned with the case start date.

  • Interest Type – Required for payout or cumulative reversions. Specifies whether values are calculated as gross or net. Not applicable for date-based types.

  • Initial Balance – Represents the starting financial position of the case (revenue minus costs). Usually zero for new wells.
