PetroLog — LAS Viewer

scroll = zoom · drag = pan

Drop LAS files to begin

Load one or several wells — everything is parsed and plotted in your browser, nothing is uploaded. Stack, overlay, map, build logs, and correlate tops.

LAS 2.0 · wrapped & unwrapped · multiple files

Coordinates stay local — only background tiles come from OpenStreetMap.

No well coordinates yet.
Add latitude / longitude in a well's Settings.

Crossplot

No matching curves. Load wells with common curves, then pick axes in the sidebar.

Toolbox computed curves & QC

Well preview scroll = zoom · drag = pan

Load wells first, then use the tools to compute new curves.
