The Filter wizard creates reusable filters that restrict well-related operations (property calculators, well-based gridding, petrophysics selections, well export) to a subset of the project's wells. In the current build, filters only support Wells data. Two modes are available:

• By expression (automatic) — the filter is defined by a regular expression (ECMAScript syntax, case-insensitive) matched against the well name and, if present, its LAS curve names, checkshot names, comments, and raster/inclinometry names; membership is re-evaluated automatically whenever the well list changes.
• Manual — the user picks items explicitly from a tree of all project objects.

Launching the wizard

In Data manager, expand Wells and right-click the Filters folder, then choose Add filter to create a new filter, or Edit filters to open the wizard on the existing set.

Input Parameters

• Filter name — unique label. The wizard refuses duplicates.
• The filter name is edited in place in the All filters list; the editor turns red with a tooltip while the name is empty or already used.
• Mode — By expression or Manual.
• Expression editor / tree view — both sit together in the left-hand Filter parameters group; the expression text also narrows which rows the tree displays. In By expression mode the tree's checkboxes are hidden (membership comes from the regular expression); in Manual mode checkboxes appear so items can be picked explicitly.
• All filters list — right-click an existing entry for Copy or Remove, or right-click empty space for Create new filter, so multiple filters can be maintained in parallel.

Results

Saved filters appear under Filters in the Data manager and can be applied to any procedure that accepts a filter argument (exports, property modelling, QC tools).
