Abstract: 

In this presentation we present some of the activities from the MinEx CRC/Loop Consortium/DARE ITTC work on building 3D geological models using geophysical data. The talk will briefly highlight the following areas:

Integration of automatic implicit geological modelling in deterministic geophysical inversion (https://doi.org/10.5194/se-15-63-2024)

Some results from the Tomofast-x inversion platform, with its ability to use detailed petrophysical statistics as constraints on gravity/mag inversion (https://doi.org/10.5194/egusphere-2023-2243, https://doi.org/10.1190/geo2019-0633.1)

The use of a massive library of synthetic 3D geological models and their gravity and magnetic response as a Machine Learning training set (https://doi.org/10.1016/j.cageo.2021.104701, https://doi.org/10.5194/essd-14-381-2022) and

Our latest work on navigating regional geophysical data using a combined feature extraction/non-linear dimensionality reduction technique method.

It is my pleasure to invite you to the upcoming SEG Distinguished Instructor Short Course, on Thursday 8th February at Ayres House, 288 North Tce, Adelaide.

We have Phil Ringrose speaking on “Storage of Carbon Dioxide in Saline Aquifers”

PESA will be hosting the SEG Distinguished Instructor Short Course (DISC) on “Storage of Carbon Dioxide in Saline Aquifers – Building Confidence by Forecasting and Monitoring” presented by Phil Ringrose. This one-day short course will be held in Adelaide on Thursday, February 8th 2024. In this course, the science and technology underpinning CO2 storage in deep saline aquifer formations is reviewed using insights from several industrial-scale projects. The main factors, which limit storage capacity are analyzed - constraints governed by flow dynamics, injectivity, pressure development, and geomechanics. Then, this physical basis provides a framework for determining how to optimize monitoring methods.

All those interested in understanding the state of play in saline aquifer CO2 storage technology will benefit from this course. The primary target audience is multi-disciplinary subsurface teams, and the content covers relevant aspects of geoscience, geophysics, and reservoir engineering.

Philip S. Ringrose is a Specialist in reservoir geoscience at Equinor and Adjunct Professor in CO2 Storage at the Norwegian University of Science and Technology. He has been engaged with many CCS project developments over the last 15 years and has published widely on reservoir geoscience and fluid flow in rock media, including the textbooks Reservoir Model Design and How to Store CO2 underground.

Ringrose holds a BSc in geology from the University of Edinburgh and a PhD in applied geology from University of Strathclyde in Scotland.  He is a member of SEG, EAGE, and the Geological Society (London), and was the 2014-2015 President of the EAGE. In 2018 he was appointed as Honorary Professor at the University of Edinburgh and in 2020 he was elected as a member of The Royal Norwegian Society of Sciences and Letters (DKNVS).

ACT Tech Talk: An Interactive workflow for MT data using open-source packages and HPC

Thursday, November 23, 2023
1600 AEST
1640 AEST

Title: An Interactive workflow for MT data using open-source packages and HPC

Presenters: Jared Peacock (USGS) and Karl Kappler (DIAS Geophysical and Space Science Institute)

Date and time: 4pm (AEST time), 23rd Nov 2023

Abstract: 

The magnetotelluric (MT) community has traditionally been composed of specialists, however with the advancement of accessibility to equipment, data, and high-performance computing more non-specialists are interested in MT data.  Open-source tools exists for working with MT data; however no publicly available coherent workflow exists.  We present a workflow for MT data that demonstrates how to use existing open-source software packages to go from raw data to a 3D resistivity model. This workflow increases the capacity of MT data to be used for open science following FAIR principles.
