PetraMatrix loads, edits, splices, and quality-checks LAS well log curves in one focused desktop app — built around how petrophysicists actually work through a well, track by track.
These are the tools petrophysicists reach for most — laid out like the tracks of a log plot itself, because that's the mental model the whole app follows.
Freehand, erase, flatline, and interpolate-line tools for hand-editing a curve directly on the plot — spikes, tool failures, washouts, corrected in place.
Merge a primary and backup run into one continuous curve, or patch a specific interval from a secondary log — with a visual pin-based interface.
Stretch-and-squeeze depth correction with draggable tie pins, for aligning a run against a reference log or known formation tops.
Build conditional output curves from rule-based term-and-condition logic — save the whole setup as a reusable named template.
Loading, organizing, and protecting the data is as much a part of the job as the editing itself.
Load and switch between multiple wells in one session, each with its own curves, layout, and edit history.
Merge a second run into an already-loaded well even at a different sample rate — depths reconcile automatically.
Multi-level undo across edits, with a dedicated history for the Log Editor's own drag-based tools.
Save a track arrangement — curve order, scales, colors — and apply it instantly to any other well.
Every edit saves continuously on your machine. A one-click Backup Workspace also exports everything to a portable file.
Straighten a drifting SP curve against a chosen shale baseline, interval by interval.
Standard arithmetic and unit-aware curve math without leaving the app to reach for a spreadsheet.
Every loaded curve listed, named, and unit-labeled — editable in place if a header comes in wrong.
