PRODUCTS

In this field we offer the following products developed by dGB, world leader in geophysical analysis and reservoir characterization:

OPENDTECT

Opendtect is the open source seismic interpretation environment that can be used to process, visualize and interpret multi-volume seismic data using seismic attributes and to develop your own innovative interpretation tools via an easy plugin system. Opendtect is currently supported for Windows, Unix and Linux systems.

GDI

GDI is a general-purpose, highly flexible, quantitative interpretation software system. Main applications are seismic lateral prediction, seismic pattern analysis and rock physical / petrophysical analysis. The system consists of a number of modules to integrate, manipulate, process and analyse the data. GDI runs on UNIX systems. Currently supported operating systems are Sun-SOLARIS and PC-LINUX.

The software can be purchased in three parts:


GDI-START

  • 2D, 3D and 4D reservoir characterisation
  • stratigraphic analysis
  • non-linear inversion using neural networks
  • facies/pattern analysis
  • rock physics studies
  • free-format integration of seismic, well and geological data

Porosity prediction


GDI-SIMULATE

  • more detailed reservoir characterisation
  • for areas with low well coverage
  • geology-based pseudo-well simulator
  • stochastic inversion
  • Gassmann fluid replacement module
  • Markov chains-based sequence analyser


GDI-PRESTACK

  • AVO modelling
  • PP, PS, SP, SS-wave modelling
