OpendTect supports the most advanced fault attributes available in the market through its Faults and Fractures plugin. Thinned Fault Likelihood or TFL is designed particularly for mapping and imaging faults and fractures based on their dips and strike range. The output is a probability volume with a razor-sharp image of the faults that can be used to extract fault planes.

Superior fault imaging using OpendTect's Faults and Fractures plugin

In this short demo, we use the Parihaka 3D dataset, which is known for its fault system that is defined by a series of NE-SW trending segments forming an en echelon fault (Giba et al., 2012).

To understand the detailed geometry of the faults, their orientation, and the evolution over geological time, TFL is computed and extracted along densely mapped horizons. The purpose of this step is to visualize the fault volume using a 3D slider. TFL results on sections and along the stratal slices depicts the differently oriented Parihaka fault segments.
