Introduction

The initial idea behind GIM was to create an automatic approach to seismic interpretation in the Geocap software. The idea arose late in 2006 and a project plan was put together with the main objectives to:

  1. Track all the sections of a 2D seismic dataset (alternatively 3D inlines and crosslines),
  2. Combine all tracking data to grid surfaces (1000's) into a surface database.
  3. Interpret seismic data interactively identifying/selecting and combining surfaces from the surface database.
  4. Analyze the surfaces in the surface database, and filter for geometrical shapes, e.g. clinoforms, truncations, onlaps, wedges, 4‐way dip closures etc.

In 2007, the project was accepted by the Norwegian Research Council as a SkatteFUNN project, and the additional support from RWEDea, Det Norske Oljeselskap, and Concedo, gave the project the financial framework needed to get going. Two new members joined the consortium in 2010.

The GIM workflow

To be able to operate GIM, it is assumed the the user has created a Geocap project with 2D or 3D seismic data. The GIM processing is given with the following main steps:
