Auditable volumetrics for fast and effective evaluation of hydrocarbon resources Within the newest release 2018.2, GeoTeric is enhancing the exploration workflow by introducing a ‘Volumetrics’ tool which allows calculation of oil and gas resource estimates at any point during horizon interpretation ...
The latest GeoTeric patch contains extensions to our recently released Validate module as well as enhancements to the rest of the application.
GeoTeric’s Fault Expression is an intuitive and flexible tool that allows the user to produce fault attributes, blends and detect volumes in one simple workflow. By providing a range of different parameters, the results can be optimized for any size or style of fault. In this blog post, we will go through the process for successfully producing all of the products available in Fault Expression. Later posts will focus on optimizing for different types of faults.

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.
Tracking and Fill Modes
GeoTeric’s Adaptive Horizons have a variety of tracking and fill modes to allow the interpreter to extract a horizons surface in a fast and accurate way, while being cognitively intuitive. GeoTeric’s tracking modes are interactive as all the possible routes through the data are determined using Graph Theory, and can be previewed in both the 3D viewer and in the 2D Interpretation window. The Fill modes can be easily chosen in the Base Map window or in the 3D window if tracking on a probe.
As part of the Cognitive Interpretation workflow, GeoTeric’s new Adaptive Horizons use Regional Structural Awareness to create the fastest and most accurate 3D seismic interpretation. Any seismic, attribute or HSV colour blend volume can be used as a source for the Adaptive Horizons (which can be interpreted in both the 3D scene or using a 2D interpretation window), with different auto-track fill options ranging from Waveform, Amplitude, PDF and Graph Theory depending on the source data and objectives. A variety of tracking modes are also available: Full line, Piecewise and Manual, all with interactive previews due to the Regional Structural Awareness. More details on these and other options will be covered in the next blog post.
GeoTeric 2017.1 is our biggest release yet with lots of new functionality. 2017.1 launches our brand new unified seismic interpretation platform with the new Adaptive Horizons, harnessing the power of cognitive decision making.
With the release of GeoTeric 2016.2.1, the user can now take advantage of the new Stratigraphic Slicing workflow. This workflow allows the user to rapidly create a series of stratigraphically conformant slices which can then be used to extract data from any of the volumes or colour blends available in their project. The Stratigraphic Slicing workflow consists of the following steps:
GeoTeric’s Adaptive Geobodies changed the paradigm of geobody generation. The tool doesn’t rely on the standard threshold technique, where the user sets an opacity value in order to tell the software which attribute values to ignore.
