Data viewer

Drop in a LAS well log to explore its curves on a shared depth track, or a CSV/TSV to plot any columns — free, right in your browser. A better, faster alternative to the usual viewers, with more formats on the way.

Drop a LAS or CSV file, or click to browse

Free — nothing is uploaded. Your data is parsed and charted right here in your browser.

Supported today: LAS 2.0 well logs (.las) and delimited data (.csv, .tsv, .txt), up to 25 MB free. More coming.
