Latest Release

Discover a deeper level of subsurface understanding with increased speed and accuracy. Geoteric 2020.1 now brings expertise in deep learning and combines it with 30 years of geological interpretation experience to revolutionise your workflows. With an easy-to-use interface, you can quickly integrate customised Geoteric networks into your workflows and start informing your decisions with an enhanced understanding of the Earth.

Collaborative Artificial Intelligence (AI) interpretation techniques are based on neural networks that extract fault information. These AI results directly integrate into your existing Geoteric interpretation workflow and also feed into the automated fault stick extraction, either regionally or within a reservoir zone of interest.

Desktop Geoteric 2020.1 also provides updates to the creation of multiple surfaces from interpretations in one easy selection and bug fixes which target interpretation workflows.

This release of Geoteric 2020.1 will be on Windows only, with a Linux version to follow.

Key areas of updates in Geoteric 2020.1

  • Collaborative AI Faults
  • Automated fault stick extraction between horizons
  • Create multiple interpreted surfaces at once
  • Bug fixes

Collaborative AI Faults

AI provides a significant new tool for fault detection and extraction in addition to conventional workflows. Geoteric includes collaborative AI interpretation techniques to extract fault information via pre-trained deep learning convolutional neural networks (CNNs). The networks have been pre-trained to recognise faults from different seismic basins and with varying data quality. Therefore, the input can be seismic amplitude from any region or geological environment, quantity, or scale, in time or depth. The output is an AI confidence visualisation which can be visualised using the many volume visualization techniques within Geoteric.

Fine-tuning is possible using interpreted fault sticks which are added to the network when it is submitted for calculation.

An interpreter can instil additional geological knowledge by fine-tuning the network with additional information. To achieve this, interpreted fault sticks are used to tune the network to the geological environment.

Automated fault stick extraction between horizons

For interpretation of faults targeting a zone or stratigraphic layer of interest, the automated fault stick extraction introduced in Geoteric 2019.1 has been greatly improved so that upper and lower constraints can be used to limit your fault stick extraction.

As well as an update to the algorithm to improve the quality of the fault stick extraction, parameters within the dialog now relate to real-world units of measurement instead of voxel units, and an interval velocity can be applied if a project is in time. Whilst you are free to manually choose the detection threshold, an automated method provides an enhanced extraction technique that uses enhanced parameters throughout the volume for better and fast extraction of fault sticks.

Create multiple interpreted surfaces at once

An update, which limits the repetitive task of creating surfaces from interpretations is enabled through selecting multiple interpretations at once for conversion to surfaces. When creating interpretations, they can be made into smoothed surfaces. In previous versions, this conversion was only possible one interpretation at a time. In Geoteric 2020.1 it is now possible to select multiple interpretations in one go and then create smoothed surfaces at once, with the same smoothing parameters.
