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...

Fault Enhancement - the fine print in Fault Expression

Posted by Peter Szafian on 07 Aug 2018

One of the most popular applications of GeoTeric’s Reveal module is the Fault Expression. Its example driven framework enables rapid optimisation and co-visualisation (CMY blending) of three independent edge attributes ensuring that faults of different sizes and seismic expressions are identified and detected with confidence. 

A great value of the Fault Expression tool is that the effects of the different parameters can be immediately assessed: there is no need for extensive testing and comparisons, because after adjusting the filter footprints, the resulting changes are seen in the preview window. However, there is a set of parameters, which are hard wired and cannot be changed. These are the fault enhancement filters, mentioned in fine print in the Detect tab of Fault Expression. Switching between the different preview swatches, we see that the detected faults are different, even without changing the detection filter parameters. So, what do these numbers in the brackets mean?

How to optimise frequencies in a RGB colour blend

Posted by Peter Szafian on 29 Jan 2018

RGB Blends of Frequency Decomposition results are very powerful in revealing fine details of the subsurface, but the amount of information that can be extracted from such blends depends on which band-limited response magnitude volumes are used as an input. Selection of the right frequencies depends on the interval, amount of detail and objective of the analysis.

Colour Blends and Iso-Proportional Slicing Attributes

Posted by Peter Szafian on 23 Nov 2017

GeoTeric's Iso-Proportional Slicing tool allows the interpreter to create iso-slices between horizons in a proportional or conformant manner to quickly gain a better understanding of the geology. Either volumes or colour blends can be used for input. A set of attributes are calculated within the slices and displayed as maps of the horizons. When we talk about reflection seismic data, most users can explain these attribute, such as e.g. Maximum +ve (Positive) Amplitude and RMS Energy. However, we frequently get the question: How are these attributes calculated in a colour blend and what do they mean?

Azimuth, Fault Trends, Instantaneous Phase: how to convert these values into degrees?

Posted by Peter Szafian on 03 Nov 2016

GeoTeric users know that some of the attributes calculated with the software have “strange” values, which are excellent for further attribute calculations or providing visual clues, however, they are not immediately meaningful for the interpreter. This blog post deals with three of these attributes – azimuth, fault trends and instantaneous phase – and shows how the GeoTeric values can be converted into ones that are more familiar for the geoscientist.

How to create a structural-topographic horizon map in GeoTeric?

Posted by Peter Szafian on 13 Jul 2016
Office walls of exploration teams frequently feature structural-topographic maps of key horizons: topography of the horizon is encoded into colours – usually using a spectrum or a rainbow colour scale – while faults are indicated by e.g. black or red lines. We’ve been recently asked whether such an image could be produced using GeoTeric.
