For a faster way of screening anomalies to confidently interpret your geology, GeoTeric incorporates RMS amplitude calculations in the iso-proportional slicing tool and also allows the creation of a volumetric RMS cube using processes and workflows.

One way to incorporate information from FMI logs into GeoTeric is to classify fault by their trend (orientation along strike). This will allow the user to quickly correlate the orientation of open fractures/faults from FMI logs to the seismic volume, gaining a better understanding of the direction of these fractures/faults.
The Flexure attribute in GeoTeric is a mean curvature attribute, it measures the amount of deformation on a surface. The Flexure attribute is a second order measurement and therefore is not affected by the local orientation of the surface. Where the reflectors are steeply dipping or flat, the Flexure value is very low, the Flexure value will be greatest where the reflectors are deformed, for example at a fault break.

Coherence cubes calculated from 3D seismic provide a representation of the similarity (or dissimilarity) of the seismic waveforms and are therefore indicators of discontinuities in the seismic volume. One of the most common coherency algorithm employed is the well-known semblance, multi-trace correlation calculation (Marfurt et al., 1998) which identifies discontinuities and reflector distortions within the data.
