Register: Please register here by September 12th.


Course description: Geoscientists and engineers are very comfortable using seismic data sets acquired with geophones, hydrophones, and accelerometers because we have a long, well-defined set of standards for acquiring, processing, and interpreting them. However, distributed acoustic sensing (DAS) seismic measurements are rapidly augmenting, and in some cases replacing, the data from these conventional tools. Technologists are frequently unaccustomed to using DAS seismic data sets since it directly acquires relative strain or strain rate measurements and not the more familiar pressure, displacement, velocity, and acceleration data. There are also acquisition parameter selections that must be made to optimize the acquired data to accomplish the purpose of the seismic survey. This course is designed to build an intuition and understanding of the value, limitations, and applications of DAS seismic technology. In addition to the lecture and accompanying book, software will be provided, which will allow the student to interactively explore DAS seismic technology.

QLD Tech Night: Precision Impulsive: A high-productivity land impulse source.

Thursday, July 27, 2023

Title: Precision Impulsive: A high-productivity land impulse source.

Presenter: William Davie

Date/Time: 17:15, 27th July 2023

Registration: here


Precision Impulse (PI), a seismic source development company, will describe an actuator that drives a versatile seismic source. The source is portable with low environmental impact.

A new high productivity mode could acquire high quality 2D or 3D surface seismic data to find and analyze CO2 storage sites and critical minerals at lower cost with better logistics. The source can also be deployed to acquire 4D seismic data to monitor CO2 storage sites to prove integrity and to optimize geothermal energy production.


An electrical engineer with more than 35 years’ experience in the global oil and gas industry, Will Davie began his career at SLB in North Africa, including introducing early versions of wireline conveyed borehole seismic. In most areas this involved putting an airgun in a pit filled with water, a bit tricky in the desert, hence his interest in an easier to deploy seismic source.

Following operational, technical and marketing roles, Will was appointed as Chief Economist to look at how better understanding of the subsurface can be used to provide more reliable, affordable energy with lower environmental impact. This included the formation of groups to look at CCS monitoring and applications of better subsurface understanding to Water management.

Will has been working on the new seismic source with Precision Impulse since 2012.

QLD: ASEG-PESA Trivia Night

Thursday, May 25, 2023

ASEG-PESA Trivia Night Thursday 25th of May:

Henk's famous Trivia night is always a cracker; feel free to bring some friends and family or meet some new faces and make a team on the night.

Competition is fierce though and there are no prisoners in this battle of the brains.

Speaking of, Henk gave us a little teaser for this event to get the grey matter churning:


"Azaria , we know where she died "


What does it mean? Who is Azaria? 

Cryptic as ever, we look forward to seeing you there.


Please RSVP by the 22nd of May at the latest, so we can work out food and drinks. 

If you know any students or student contacts, let them know that we've dropped the charge for this event. 

AuScope Special Seminar with ChEESE Program Leader Prof Arnau Folch

Monday, February 6, 2023
1200 AEDT
1330 AEDT

HPC is increasingly being used in solid Earth Geophysics in Europe and AuScope has organised this Special Seminar with Arnau Folch, leader of the EU ChEESE Program

ChEESE is the EU Centre of Excellence for Exascale in Solid Earth and develops translational research capabilities in High Performance Computing to the Exascale in geophysics, enabling multiscale, multiphysics and multi-hazard analysis.

In this seminar, Arnau will present the results of ChEESE-1P Exascale Pilot Demonstrators, including:

·  Rapid probabilistic forecasts of tsunami inundations; 

·  Earthquake source prediction; and

·  The atmospheric volcanic ash dispersal models validated in real time against high-resolution geostationary satellite data.

And, introduce ChEESE-2P and highlight its role in an ecosystem of projects that are shaping Europe’s Digital Future, including:

·  A Digital Twin for GEOphysical Extremes (DT-GEO);

·  Destination Earth (DestinE); and 

·  European Plate Observing System (EPOS)

Date: February 6th from 12 pm to 1:30 pm AEST.

Please register here via Eventbrite.



The first phase (ChEESE-1P) ran from 2018-2022 and addressed scientific and technical computational challenges in moving existing systems to Exascale in seismology, tsunami science, volcanology, and magnetohydrodynamics. ChEESE-1P initiated the optimisation of 10 Community flagship European codes for the European pre-Exascale and Exascale supercomputers and developed 12 Pilot Demonstrators (PD) that enabled services oriented to critical aspects of geohazards, including hazard assessment, urgent computing, and early warning forecasting.

Following the success of ChEESE-1P, a second 4-year phase (ChEESE-2P) with funding of € 7.8 million was launched in January 2023. Arnau will lead a team of Earth and Computer Scientists across multiple programs that will further develop the ChEESE-1P codes and new codes in geodynamics and glaciology.

We are delighted to be hosting Arnau and welcome you to join us in what will surely be a great seminar.

ASEG-PESA "The Good the Bad and the Uncertainties - a Model of Stress State".

Friday, February 24, 2023

Presentation:The Good, the Bad and the Uncertainties – A model of the stress state

Venue: Hilton Hotel Brisbane, 190 Elizabeth Street, Brisbane QLD 4000
Victoria Room
(Detailed directions below)

Date & Time: Friday, 24th February 12:15 PM


Presentation Abstract:

The Good, the Bad and the Uncertainties – A model of the stress state

A profound knowledge of the undisturbed stress state is the basis for an understanding and prediction of effects that occur during subsurface operations. These issues, from wellbore stability to the potential for injection or production induced seismicity are relevant for safety. Safe operation is particularly important with the public as a stakeholder. An increase in subsurface usage in urban areas (for geothermal district heating) is expected in Europe due to the need to become independent from energy imports and meet the climate goals.

The limited availability of stress (magnitude) data records usually doesn’t allow a significant prediction of the stress state in an area of interest. Therefore, geomechanical-numerical modelling is applied. Available stress data records are used to calibrate a model of the subsurface that predicts the stress state at the area of interest. However, the models are subject to large uncertainties due to limited knowledge on rock properties, 3D geology, and stress magnitude data. To allow for a significant interpretation of the model results the uncertainties are quantified. Therefore, a range of different possible stress scenarios that are supported by data are modelled.

To reduce the uncertainties, additional indirect observations of the stress state are used. They are data from boreholes such as Formation Integrity Tests or the observation of Borehole Breakouts, recorded seismicity, or injection-induced stress rotations. The different stress scenarios are compared for their agreement with the indirect data. The more indirect data is in agreement with a certain scenario, the higher is the scenarios probability. Eventually, a Bayesian approach is applied to assign probabilities to individual stress scenarios. This leads to an increase in significance of the model which adds value to the interpretation.
