> Install Geo Toolkit to load LAS well logs, SEG-Y seismic, and collar surveys as entities, then krige horizons and export a watertight 3D geological model — all as native LSD steps.

## What it does

Geo Toolkit turns LSD into a subsurface modelling environment. It adds:

- **Loaders** for LAS/LAS2 well logs, SEG-Y seismic, and collar/assay CSVs.
- **Shape steps** for kriging horizons, flagging outliers, and stitching fault blocks.
- **Delivery** to a watertight 3D mesh plus a per-model report.

## Typical pipeline

Load your logs and seismic, add an interpolation step between holes, and deliver the lithology to the 3D viewer. As new holes are logged, the model re-interpolates live.

## Install

Open the package in LSD and click **Open in LSD**. Once installed, the Geo loaders and steps appear in the node palette.

## FAQ
### Which subsurface formats does Geo Toolkit load?

LAS/LAS2 well logs, SEG-Y seismic volumes, and CSV collar/assay tables, all as typed LSD entities.

### Can it update the model when new wells are logged?

Yes. Because the interpolation runs as reactive steps, adding a new log re-kriges the affected horizons automatically.
