02 Arrange the log

Rounded scales, 1.6 px curves and subtle fills. Overlay limits expand together to include source values.

Colours describe plotted curve position only. They do not identify gas or rock type.

Plot density and neutron together on fixed, opposite axes to see crossovers.

Axis limits use the selected curve's units.

Track grid

03 Shale proxy

Set reference values in the selected gamma ray curve's units.

Clean referenceShale reference

Linear index = (GR − clean) / (shale − clean), clipped to 0–1. This estimates relative shale response; it does not identify rock types.

Scale ranges & clipping

From subsurface data
to a shareable image.

Depth-aligned curves, a patterned shale proxy
and clear annotations in one export.

PNG/SVG are overview images. For true 1:200 vertical scale, use Print / PDF: A3 portrait, 100% / actual size, browser headers and footers off. Each full page covers 200 ft or 60 m.

Bring your LAS

Supports wrapped and unwrapped LAS 1.2/2.0. Nulls remain gaps. Choose up to three additional curve tracks, with linear or logarithmic scales.

Interpret with context

Crossovers need geological context. The default overlay scales use a limestone-compatible display; confirm the neutron matrix basis. Shale colours remain a preliminary gamma-ray estimate.
