Screen anomalies with RMS amplitude

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.  Learn more and follow our step by step guide to c...

Visualising Fault Trend Orientation

Posted by Randy Hee on 11 Oct 2018

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.

Using Curvature in GeoTeric 

Posted by Randy Hee on 15 Jan 2018

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.

Why Using Combined Fault Attributes Reveals More than Coherence Alone

Coherence Attribute

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.

First Method: Exporting RGB blend from GeoTeric to Petrel using GeoTeric's Link for Petrel

1. You need link-for-Petrel installed in your machine. If you do not have it installed, you can find the installer in C:Program FilesGeoTericGeoTeric 2016.2link-for-petrel. Petrel project need to be first open for you to transfer the RGB blend from GeoTeric.

Tuning Curve Analysis Part II: Creating a Tuning Classification Volume

Posted by Randy Hee on 26 Feb 2016
This is an extended workflow from an earlier Tuning Curve Analysis blog post where it shows how to generate a Tuning Curve using Terrace Amplitude and Terrace Thickness. The input for Terrace Amplitude and Terrace Thickness should be phase rotated -90 degree or Quadrature attributes of your seismic.
