ASEG Webinar: Preconditioned Compressive Sensing for Wavefield Reconstruction

Thursday, September 2, 2021
1300 AEST
1400 AEST

Title: Preconditioned Compressive Sensing for Wavefield Reconstruction, Applications to tomography, Helmholtz-Hodge decomposition and Distributed Acoustic Sensing

Presenter: Jack Muir

Date/Time: Sep 2, 2021 1300 (AEST)

Registration: https://us02web.zoom.us/webinar/register/WN_Sr40IBw9SmiEnyMh5dOY4w

 

Abstract: The proliferation of large seismic arrays have opened many new avenues of geophysical research; however most techniques still fundamentally treat regional and global scale seismic networks as a collection of individual time series rather than as a single unified data product. Wavefield reconstruction allows us to turn a collection of individual records into a single structured form that treats the seismic wavefield as a coherent 3D or 4D entity. We propose a split processing scheme based on a wavelet transform in time and Laplacian preconditioned curvelet based compressive sensing in space to create a sparse representation of the continuous seismic wavefield with smooth second order derivatives. Using this representation, we will illustrate three applications that require accurate access to the full wavefield including spatial gradients -

IMAGE '21 is the integrated annual conference and exhibition of the Society of Exploration Geophysicists (SEG) and the American Association of Petroleum Geologists (AAPG) and in conjunction with the Society for Sedimentary Geology (SEPM).

Click on the image below to view the event. 

The Society of Exploration Geophysicists (SEG), the American Association of Petroleum Geologists (AAPG) and in conjunction with the Society for Sedimentary Geology (SEPM) are excited to host, IMAGE 2021 - the International Meeting for Applied Geoscience & Energy. The three societies agreed earlier this year to hold this integrated annual meeting over the next five years, the first of which will be a hybrid event held from 26 September to 1 October 2021, at the Colorado Convention Center in Denver, Colorado and online.

As global leaders in disseminating high-quality applied-geoscience knowledge and data, SEG, AAPG, and SEPM have joined forces to create this powerhouse event bringing together multiple disciplines of the geosciences sector. IMAGE ’21 combines all the great elements from each society’s previous annual meetings under one roof to offer a better experience and increased value for the industry.

IMAGE ’21 will welcome speakers, exhibitors, and attendees to participate in-person or online, or both. The comprehensive technical program will feature more than 1,000 presentations, nearly 200 sessions, 14 post-convention workshops, 10 special sessions, five field trips, countless networking opportunities, and a joint exhibition showcasing the latest geoscience products and technologies. One registration will give delegates access to the core technical sessions, the exhibition, and several other events.

Don’t miss the ultimate learning and networking event for applied geoscience and energy.

 

Tech talk - Application of Multi-Scale Magnetotelluric Data to Mineral Exploration: An Example from the East Tennant Region, Northern Australia

Title: Application of Multi-Scale Magnetotelluric Data to Mineral Exploration: An Example from the East Tennant Region, Northern Australia

Presenter: Wenping Jiang, Geoscience Australia

When: 12th August,2021 at 11am AEST

Registation: https://us02web.zoom.us/webinar/register/WN_gKKtAD8MRwaRCNUp-DNwNA

Abstract: 

The footprint of a mineral system is potentially detectable at a range of scales and lithospheric depths. Magnetotellurics is one of few techniques that can provide multi-scale datasets to image and understand mineral systems. We have used long-period data from the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) as a first-order reconnaissance survey to resolve large-scale lithospheric architecture for mapping areas of mineral potential in northern Australia. The 3D resistivity model reveals a broad conductivity anomaly in the lower crust and upper mantle to the east of Tennant Creek, representing a potential fertile source region. Results from a higher-resolution infill magnetotelluric survey reveal a favourable crustal architecture linking the lower, fertile source regions with potential depositional sites in the upper crust. This observation strongly suggests that the deep-penetrating major faults potentially acted as pathways for transporting metalliferous fluids to the upper crust where they could form mineral deposits. This result and its integration with other geophysical and geochronological datasets suggest high prospectivity for major mineral deposits in the vicinity of these major faults. In addition to these insights, interpretation of high-frequency magnetotelluric data helps to characterise cover and assist with selecting targets for stratigraphic drilling which, in turn, can validate the models and improve our understanding of basement geology, cover sequences and mineral potential.

This study demonstrates that integration of geophysical data from multi-scale surveys is an effective approach to scale reduction during mineral exploration in covered terranes.

Biography: Dr Wenping Jiang joined Geoscience Australia in 2012 after completing a PhD degree from the University of Sydney. Since Feb 2016, she has worked as a senior geophysicist in the Mineral Systems Branch, delivering precompetitive data and information to improve the understanding of mineral resource prospectivity. Her professional focus is mainly on Magnetotelluric data processing, modelling and interpretation.

Title: Managing Through (constant) Change And Uncertainty -  The Key Dilemmas Facing Resources Industry Personnel

Presenter: Michelle Henderson

Date: Tuesday  8th June

Time: 16:00 AEST  

Location: Joint Zoom virtual + physical presentation at Geoscience Australia

Abstract:

The cyclical nature of the resources industry creates very specific challenges across investment through to people management.  Faced with constant ‘instability’, often supply-limited expertise and the uncertainty over discovery, how do we hold on to our people, maintain their enthusiasm and continue to lead success?

As a professional coach across government and scientific agencies, Michelle brings extensive experience to the ‘problem’ and solution.  Her empathetic and pragmatic approach empowers professionals to not only manage change, but to enthusiastically grasp the opportunities it brings.

Latin Geophysics Explore

Tuesday, July 27, 2021

The initial geophysics conference “Looking into Our World”, provided us with a platform to develop and learn from. As such, this year’s event will come under the banner of “Latin Geophysics Explore 2021” which better reflects nature of the conference since the science is not dictated by political boundaries but by geoscientific ones.

Building on from last year we wish to grow the event to include a half day training course to complement the speaker program maintaining a similar structure to last year.

A programme can be accessed here.

A personal reflection on applied geophysics to the understanding of Australia’s geology and mineral potential

Tuesday, March 30, 2021
1730 AEST
1830 AEST

Date: 30th March 2021

Time: 5:30 - 6:30pm AEDT

Register: https://us02web.zoom.us/webinar/register/WN_J6zK4TXCTbCI1PxCI4uF9g

 

Richard retired from Geoscience Australia after more than a 30 year career of developing new geological understanding to open up provinces for exploration investment. Applied geophysics played a key component throughout his career, and this seminar will be a personal reflection on the key ‘geophysical-aha’ moments that have changed his understanding of a region’s geology and, through this new knowledge, Australia’s mineral potential.

The 30-year story begins in the field as a young geologist using geophysics to map Cape York, Pilbara and Yilgarn and seismic transects across a number of Proterozoic orogens, through the UNCOVER formulation to the lead designer of the Exploring for the Future programme.
