Getting warmer: the search for geothermal resources in Tasmania

Title: Getting warmer: the search for geothermal resources in Tasmania

Presenter: Dr John Bishop, Spa*ark Energy

Date: Thursday 28th April

Registration: https://us02web.zoom.us/webinar/register/WN_NRi6Imp9T9-en85l2oSRdQ

Abstract:

Geothermal power plants provide emission-free, baseload or load-following (i.e., dispatchable) electricity 24/7 from the smallest footprint of all generators. And excess heat from the plants has several applications including drying, aquaculture, spas, etc.  Two large, code-compliant inferred geothermal resources have been defined in eastern Tasmania, associated with some of Australia’s highest recorded heat flows. A suite of geophysical surveys suggests that one has zones of high permeability, making it akin to a conventional hydrothermal play, albeit a non-volcanic one.  Recent developments in mineral extraction from geothermal brines add to the potential utility of the resources.

Asia Pacific Meeting on Near Surface Geoscience & Engineering

Asia Pacific Meeting on Near Surface Geoscience & Engineering returns for its 5th edition and the flagship conference on Near Surface APAC is set to be held from 6-9 March 2023 in Taipei, Taiwan. As we concluded the last edition, we  are pleased to welcome all of you to a yet another successful conference in Taipei, Taiwan next year. 

This year's conference is Co-Organized with Taiwan Geotechnical Society (TGS) and National Yang Ming Chiao Tung University, Taiwan under the overarching theme of: Global Challenges and Regional Experiences. The theme is set as it is important to welcome submissions that focus on the challenges faced by the Near-surface industry; regional centric as well as globally. 

If you are interested to share your work and be part of the speakers' line-up, submit your extended abstract  before 15 November 2022.

Title: Would you know a good decision if you saw one?

Presenter: Emeritus Professor Steve Begg, University of Adelaide; and, Decisions, Decisions

Date: Friday 29th April

Time: 1730 (for 1815)

Cost: Free (members). $10 - non-members

Abstract:

Making decisions is a key component of most technical and managerial jobs – the only bit of control an organization has over its future are its decisions (and their implementation), the rest is  up to nature, chance, decisions of others … all uncontrollable.  Like many other spheres, good decision-making abilities do not arise from “natural talent”, but from learning and developing a set of skills, honed by experience.  But most people have not been taught how to make good decisions in uncertain, complex or novel situations – or even what a good decision is.  This talk will introduce some key decision-making concepts (based on decision science) including the six dimensions of Decision Quality (DQ) that enable the user to make, and know they have made, a good decision (the only thing they can control) before they know the outcome.    The concepts are decision-agnostic, so equally applicable to personal decisions.

Bio:

Steve is an Emeritus Professor and former Head of School at the Australian School of Petroleum & Energy Resources (formerly ASP), University of Adelaide. His focus is on: tools and processes for decision-making under uncertainty; project/ asset and portfolio evaluations; and psychological factors in eliciting expert opinions. Steve’s prior roles include: Director for Decision Science and Strategic Planning with Landmark (a Halliburton company), a variety of senior roles for BP Alaska that spanned uncertainty in geological, engineering and economic models and Researcher and Project Manager with BP Research, where his focus was on uncertainty and variability modelling. He has twice been an SPE Distinguished Lecturer on uncertainty & decision-making topics. In 2014, he was elected to the Board of the Society of Decision Professionals (SDP). In 2016 he received the SPE’s top international award for the Management & Information discipline for his work on biases in decision-making. Steve is co-author, with Reidar Bratvold, of the book “Making Good Decisions”. He holds a PhD degree in Geophysics and a BSc degree in Geological Geophysics from Reading University in the UK and has taken executive education courses at MIT and U. Texas, Austin.

ASEG Tech Talk - Multi-parameter FWI imaging: high-resolution imaging directly from raw field data

Title: Multi-parameter FWI imaging: high-resolution imaging directly from raw field data

Abstract:

Traditional seismic processing workflows can be extremely time-consuming since subsequent stages are only begun after extensive testing and QC of the current process. This linear approach takes the raw field data and passes it through a plethora of conditioning tools (such as designature, deghosting, demultiple and regularisation) to transform the data into a form that can be imaged by legacy migration algorithms, such as Kirchhoff 3D preSDM.

Full waveform inversion (FWI) imaging is a multi-scattering least-squares approach uses the raw field data to estimate many subsurface parameters, including reflectivity, simultaneously ahead of a conventional processing workflow. Since it is using the primaries, multiples and ghosts during imaging, the result is a set of higher resolution subsurface models but in a fraction of the time of a conventional processing workflow due to the fact that little to no pre-processing is required.

In this presentation we demonstrate an 85 Hz comparison between a conventional processing workflow and a novel FWI imaging technique that utilises an augmented wave equation and an advanced optimisation scheme. The FWI imaging approach is simultaneously inverting for velocity and an intercept-reflectivity vector which is fit for structural and amplitude analysis.
