Complete Toolkit for Faults and Fractures

OpendTect Pro supports many attributes, filters and utilities for imaging faults and fractures. We have now combined all these tools in a new commercial plugin called the Faults & Fractures (FCF) plugin.

Highlights are new image processing algorithms originating from the Colorado School of Mines. These algorithms produce superior fault imaging and filtering results. In addition, the Faults & Fractures plugin supports tools to automatically extract fault planes, to un-fault data and to compute fracture-specific attributes such as fracture density and fracture proximity.

"I am overwhelmed with the results from F&F plugin, I feel this is far superior than the results from Petrel's AntTrack."

The Thinned fault likelihood attribute provides razor-sharp fault images on horizontal slices as well as on vertical sections (Figure 1). This attribute (and/or volume curvature-type of attributes) can be used as input attributes for fracture density and fracture proximity attributes (Figure 2).

This new plugin also comes with a new, edge-preserving smoothing filter. This smoothing algorithm uses Thinned Fault Likelihood attribute as input. It generates seismic volumes with razor-sharp edges that are very well suited for structural interpretation (Figure 3). For further quantitative work milder filters such as the dip-steered median filter are needed.
