Webinar - Geological Knowledge Discovery using Machine Augmented Intelligence.

Thursday, January 28, 2021
1300 AEDT
1400 AEDT

We have another exciting year of ASEG webinars kicking off next week with a new webinar on Thursday 28 January, 1pm AEDT by Professor Eun-Jung Holden from the University of Western Australia on Geological Knowledge Discovery using Machine Augmented Intelligence.

Geological interpretation is a complex task where an interpreter’s bias plays an important role. As a result, interpretation outcomes are variable and uncertain, but nevertheless, these outcomes form the basis of decisions with significant environmental, social and financial implications. With the increasing use of artificial intelligence and machine learning in our daily lives such as for information search, online shopping, and virtual assistant AI, the geoscience domain has also been active in the uptake of machine learning and AI to assist in interpreting geology from data.

This talk presents innovative machine-assisted technologies that improve the efficiency and the robustness of geological interpretation of different types of geodata used in the resource industry. A number of applications of machine learning were developed in collaboration with the mining industry for the analysis and integration of multi-modal drill hole data. These applications integrate the algorithms and workflows to assist human decisions. The approach is to provide end users the control of the algorithmic process as much as possible; and to enable a seamless integration of algorithms in the interpreter’s workflow using interactive visualisation. This talk also presents an on-going AI research that extracts geological insights from documents using machine reading of text. It applies advanced text mining methods and constructs a graph based knowledge base called a knowledge graph to store and access geological information. Case studies on different mineral deposits demonstrate the effectiveness of the methods for rapidly and robustly transforming text data into structured information that faithfully represents the contents of the source reports.

WA Webinar CASE STUDY : Efficient exploration in the Bonaparte Basin Using Unstructured Data Analytics with ElasticDocs

Wednesday, December 16, 2020
1200 AWST
1300 AWST

Presenter: Ain Nadrah Noor Sazali, Iraya Energies

Title: CASE STUDY :  Efficient exploration in the Bonaparte Basin Using Unstructured Data Analytics with ElasticDocs

Abstract:

Mining and Oil and Gas companies are awash with data from many different disciplines, the amount of data is growing exponentially and is estimated to double every 12 to 18 months. The diversity of the available data is such that it is impossible for any single user to efficiently access this information and knowledge. In recent years, these industries have been turning to finding new ways of tackling this challenge, using Big Data and Machine Learning technologies. In Iraya, we have developed ElasticDocsTM,  an intuitive knowledge container, capable of automatically ingesting and structuring reports, images and presentation using machine learning.

We will present a case study covering the entire Bonaparte Basin for Play Based Exploration (here, for Oil and Gas potential).The technology will be used to address the five most common potential challenges during a geological study: (i) Discrepancies in formation tops, (ii) Limited understanding of lithology distribution, (iii) Limited mineral composition understanding, (iv) Fluid distribution, (v) Pressure/temperature patterns. We will demonstrate how such analysis can be conducted in ElasticDocs and how much time and resources are saved by the geoscientist mining these vast amounts of unstructured data such as reports (G&G, drilling, production), presentations (studies, analysis, summaries), images (cores, thin sections), spreadsheets and tables.

Bio:

Ain Nadrah Noor Sazali is a Digital Earth Scientist in Iraya Energies. With her diverse background of domain expertise (geology, petrophysics) and  also in Data Science, she designs and deploys innovative machine learning and artificial intelligence solutions for unstructured data using ElasticDocs to support the geoscientists and engineers decision making. She holds a MSc in Petroleum Geology, a BSc in Industrial andComputational Mathematics, and a Diploma in Science Physics.

Webinar: Exploring for minerals, not anomalies: Developing quantitative interpretations of MT models. Dr Kate Selway, Macquarie University

Thursday, February 25, 2021
1300 AEDT
1400 AEDT

1pm AEDT February 16th,

Dr Kate Selway, Macquarie University.

Title: Exploring for minerals, not anomalies: Developing quantitative interpretations of MT models.

Abstract: Exploration geophysicists are well acquainted with making quantitative interpretations of near-surface geophysical data. There is a good understanding of how shallow anomalies in potential field, resistivity or EM datasets relate to mineralisation. However, as exploration models begin to include the lower crust and the lithospheric mantle, there remain significant gaps in our interpretation of deeper geophysical data. In this talk, I will highlight some new advances in our ability to produce quantitative interpretations of these deeper geophysical data, with a particular focus on MT and its joint interpretation with seismics. I will show the newly released software 'MATE', which allows MT models to be interpreted in terms of temperature and composition, and discuss new results from the Eastern Goldfields Superterrane of the Yilgarn Craton, which show how quantitatively interpreted MT models can feed into improved exploration strategies.

Bio: Dr Kate Selway is a geophysicist and researcher who specialises in the MT method and improving interpretations of mantle geophysics. She recently completed an ARC Future Fellowship based at Macquarie University and has previously held research positions at the University of Oslo, Lamont-Doherty Earth Observatory, Yale University and the University of Adelaide, after completing her PhD at the University of Adelaide in 2007. Her research has spanned giant mineral deposits in Australia, active rifting in East Africa, and mantle uplift in Greenland and Antarctica.

Webinar - Seismic imaging of the crust using Bayesian joint Inversion of teleseismic P-wave coda autocorrelation waveforms.

Tuesday, February 2, 2021
1230 AWST
1330 AWST

On Tuesday 2 February, 3:30pm AEDT FedEx is bringing you a talk by Dr Mehdi Tork Qashqai from the CSIRO on Seismic imaging of the crust using Bayesian joint Inversion of teleseismic P-wave coda autocorrelation waveforms.

Deep crustal-scale structures are critical for controlling and development of a wide range of mineral deposits. Incoming seismic waves generated from teleseismic earthquakes can be used to image the deep crustal structures. Traveltimes of the teleseismic P and mode-converted S-waves and their reverberations place a tight constraint on the Vp/Vs ratio, and their amplitude ratio provides tight bounds on the P and S wave velocity jumps across the main discontinuities/boundaries in the subsurface structure below a seismic receiver. Teleseismic P-to-S converted waveforms have been used for decades to estimate the shear-wave velocity of the subsurface and depths of major discontinuities below a seismic receiver through a method known as the P receiver functions. In this presentation, a new and alternative approach is presented. Waveforms associated with the P and all mode-converted shear waves are extracted by the autocorrelation of the teleseismic P-wave coda recorded on the radial and vertical component of a three-component receiver. Then, these waveforms are jointly inverted using a probabilistic joint inversion framework to simultaneously estimate seismic properties of the crust (Vp, Vs and Vp/Vs). This approach is particularly useful when there are no high-quality and reliable receiver function waveforms. This approach is cost-effective and can be used in conjunction with the inversion of receiver function, or the deep active seismic reflection profiling to obtain additional/complementary information on the subsurface structure, especially at middle and lower crustal depths where the deep seismic reflection method has penetration problem. In this presentation, I will show some synthetic and real data examples to confirm the feasibility of this imaging technique and also to encourage further application of this approach.
