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:

  1. Optimize the cube
  2. Test different tracking parameters to achieve best possible result.
  3. Track the whole dataset according to the tested tracking parameters.
  4. Generate GIM seismic which makes it possible to bring the high resolution of the GIM tracking into other seismic interpretation systems.
  5. Generate GIM surfaces from tracking data.
  6. Generate attributes.
  7. Seismic interpretation by combining surfaces from the database.
  8. Generate 3D bodies

Menu system

The GIM menu system can be found under Tools. The system is divided into 5 main parts:

  • Data generation  
    • This is where all GIM data is generated: GIM seismic, tracking, surfaces, and attributes.
  • Data visualization 
    • This is where one visualizes surfaces by graphical selection, surface scan, tracking or surface data from list selection, or tracking scan
  • Interpretation 
    • Seismic interpretation based on GIM surfaces.
  • Analysis
    • The is where one performs analysis on tracking, and surfaces + body generation.
  • Data management
    • This where one can look at properties, rename, and delete datasets in the GIM database.
