Introduction

The seismic interpretation tool lets you interpret horizons, faults and observations. This can be done both manually and automatically. In your Geocap project you will typically have an interpretation folder with one or more Ihorizon datasets, one Faults folder and one Observations folder.

The structure of a horizon in Geocap is as follows:

• One horizon can contain interpretation for several seismic lines
• Each line can have many segments
• Each segment can have many picks

This means that each horizon will normally contain thousands of picks along different seismic lines. Each pick is stored with the following information:

• Time value
• Seismic line name
• Shot point

The way Geocap stores its horizon data is compatible with most other seismic interpretation systems.
