Ava Clastics delivers key functionality updates


Wednesday, December 13th, 2018:
Today we announce the 2018.12 release of Ava® Clastics sedimentology and analogue database software, which marks the completion of the original vision set out for our product.
Updates include extensive visualisation and filtering capabilities for all three sedimentary analogue databases (FAKTS, SMAKS and DMAKS), created by world-leading researchers at the University of Leeds; the ability to model facies at different scales with three different algorithms; a combined Ava Clastics-Saturation plugin supporting the latest versions of Petrel; options to share depositional concepts between users; the ability to export a comprehensive report for each depositional concept, and more.

Improved Facies Modelling of Shallow Marine Environments

Using facies proportions, spatial distributions and relationships, Truncated Gaussian Simulations (TGS) allows the reproduction of a depositional setting over an area of interest. Ava Clastics now supports modelling using the TGS algorithm (without trends) to model shallow marine systems. To do this, we’ve developed a new suite of GeoCypherTM logic rules to translate analogue data ranges into the numerical parameters required for the TGS algorithm.


Ava Clastics Modelling Scale


In addition, to allow the modelling of depositional belts and tracts in shallow marine systems, which can also be combined with the TGS facies modelling algorithm, we’ve added three new hierarchical scales of analogue-informed modelling.

Facilitating Collaboration
With multiple stakeholders and transitory teams, keeping a detailed record of modelling workflows is vital, especially when it comes to compiling reserves estimates, production volumes and field development plans.

Ava Clastics DC Sharing

To facilitate collaboration across multi-user teams, Ava Clastics now allows users to share Depositional Concepts (DCs) with colleagues. But we take confidentiality seriously. DC sharing is restricted by default to peer groups within the same company. External DC sharing with other parties (e.g. university collaborators, PDS geoscientists or joint-venture partners) can securely be arranged if required.
We’ve also enhanced the automated report generation. A single click will produce a comprehensive PDF file report of all the details in your Depositional Concept, including charts, filters, references, modelling parameters and comments, as a record or audit trail.

Continuous Improvements to the Ava Experience and Making it More Intuitive
Our fluvial, shallow marine and deep water databases continue to grow and Ava Clastics now includes the most recent versions from November and December this year. And it’s not a one-time only thing. Growing the databases never stops. As and when the researchers at Leeds incorporate new data, we’ll ensure it is included in Ava Clastics too.
We’ve also optimised the loading of the data within the databases meaning browsing and filtering of the analogues is now quicker and more efficient than ever before.
Based on user feedback, we’ve implemented a range of improvements across the application to ensure the user interface is intuitive and easy-to-use.
Finally, we wanted to provide a seamless experience for users who hold licences for both Ava Clastics and Ava Saturation. To that end, we’ve combined the Petrel* plug-ins for each application, so you can now utilise them from a single plug-in.

Let us know what you think
Although it’s widely considered best practice to use analogue data in facies models, the process is time consuming, somewhat subjective, and highly variable depending on domain expertise. We’ve built Ava Clastics seamlessly inform reservoir models, so asset teams can quickly assess the impact of incorporating high-quality analogue information. We have many ideas on where Ava Clastics can grow, but no idea is as important to us as yours. If you have ideas of how Ava Clastics can be improved, please visit our website to leave your feedback.
More information about the 2018.12 release is available in the release documents (User Guide, Known Issues and FAQs) which subscribers can download directly from the Ava Clastics landing page.
