Open a LAS file and plot well logs online
Load a well-log LAS 1.2 or 2.0 file and place any of its curves on four depth tracks. Use GR, resistivity, density, neutron or sonic logs together, with independent scales and line styles. File contents are processed in your browser.
Add meaningful fills
Fill to a baseline such as GR 75 gAPI, or between two curves. Left and right colours follow displayed positions, including reversed and unequal scales.
Save and reproduce
Export the visible plot as a PNG with legends. Save JSON settings and reload them alongside the same LAS to restore tracks, depths and fills.
