• OpendTect Pro – “The seismic interpretation solution for professionals”
• New algorithms for HorizonCube, Faults and Smoothing
• When to expect
OpendTect Pro Motivation
•
OpendTect is used by thousands of specialist users for data visualization, attribute
analysis and advanced seismic interpretation work flows
•
The system is currently not used by many for conventional seismic interpretation
tasks like horizon tracking, fault interpretation and mapping
•
In the current market we believe there is a place for a modern, efficient, in-expensive
seismic interpretation solution
•
Against this background we started a series of development projects aimed at
improving OpendTect’s seismic interpretation work flows. To compete more
effectively in this space we will launch a professional version of OpendTect called:
OpendTect Pro

Improving Interpretation Work flows
• Overhaul of existing 2D viewers
• Improving 2D Horizon Tracking work flows
• Improving Fault Interpretation work flows
New 3D Auto-tracker
• Complete overhaul of OpendTect’s
3D tracker
• Highly interactive work flow
• Easy editing and switching between
modes
• New data structures for increased
speed

New 3D HorizonCube Algorithm
More Accurate HorizonCubes:
• Based on work by Wu and Hale*
• Constrained inversion of the dip-field
• Advantage: error is globally minimized
• Constraints are user-picked positions on
multiple seismic events
Additional Benefits:
• New set of fault attributes
• Automatic fault planes

Example New HorizonCube Algorithm
Australian NW Shelf
Interval is characterized by
successive phases of
erosion and sediment infill
The algorithm correctly
maps all major trends in this
very difficult setting
New Fault Attributes
OpendTect v5.0:
FEF+Similarity (current best
solution)
New thinned fault likelihood
Automatic Fault Planes
Automatically extracted fault
planes from new thinned
fault likelihood attribute
Fracture Attributes*
Fault likelihood attribute is
used as input to directly
compute denstiy of fractures in
a given area and the proximity
(or connectedness) of fractures
with each other.
Increasing threshold cut-offs
on the fault likelihood attribute
highlights the most prominent
areas in (c) and (f).
Fracture Proximity
* Already available in v5.0
Fracture Density
Example: Raw seismic + FEF similarity
OpendTect v5.0: current best
solution
Example: Smooth seismic + Fault Likelihood
