1.1. About OpendTect

OpendTect is a seismic interpretation system, as well as an R & D platform, for developing innovative seismic interpretation tools. The system is released as an Open Source Base system that can be extended at run-time with (commercial) plugins. The Base system runs without license managing restrictions and is free for R & D, education, and evaluation. Commercial users are asked to pay a modest maintenance fee (see License Agreement). Commercial plugins are closed source and require a license key to run.

This manual describes the functionality in the Base system. Manuals for the commercial plugins have their own help files (e.g. the commercial plugins by dGB--dip-steering, neural networks, SSIS, inversion plugins--are described in the "dGB plugins Help file").

This version of OpendTect Base system features:

Visualization and analysis of 2D and 3D seismic data in a single survey
Sophisticated 2D and 3D horizon tracking including auto-tracking, plane-by-plane, line and manual tracking
On-the-fly calculation and visualization of various attributes and filters
Multi-platform distributed computing
Plug-in architecture
