How LAS Import Works

From a .las file on disk to a worksheet of curves in three steps.

Open the LAS Import pane

Pick LAS Import from the Tools group on the Petroleum Office ribbon. The pane opens with three sections: file selection, curve preview, and import options.

Pane: Step 1 expanded with empty path, Steps 2 and 3 collapsed

Load the file and pick curves

Click Browse & Load and pick a .las file (both LAS v2.0 and v3.0 are supported). The pane parses it on the spot and lists every curve with its unit and description.

Import to Excel

Tick the curves you want, leave noise unchecked, then click Import to Excel. The pane confirms how many curves and samples landed.

Curves arrive as a dedicated worksheet

The curves land in columns next to the well-header metadata — one worksheet per file, ready for crossplots and petrophysical analysis.
