Workshops

The Scientific Committee invites you to participate in the pre-conference workshops on offer at AGC2022. All pre-conference workshops will take place on Sunday 20 November 2022 at The University of Western Australia. 

Bookings essential through the Registration Form.

Workshop 1 – Characterising aquifers with wireline logging using petrophysical techniques
Date Sunday 20 November 2022
Time 1000 – 1630
Price $250.00 standard
$125.00 students
Lead Facilitator TBC
Description In the oil and gas industry the reservoir is characterised using a range of geophysical techniques that measure properties such as porosity, permeability, fluid salinity and others. Recently, many of these techniques and workflows have started to migrate across to the groundwater sector, driven both by a greater access to these logging technologies, and by the need to better understand and manage the aquifers. This workshop will review some of the key wireline logging tools that can be used in the groundwater arena, focusing on developing a general understanding of the physics behind the measurements, as well as their application to compute geophysical properties. Basic interpretation concepts will be discussed to show how combining different measurements can be used to determine in-situ properties such as water salinity, amount of resource in place and producibility of the well.
Workshop 2 – Methods and perspectives for uncertainty quantification
Date Sunday 20 November 2022
Time 1000 – 1600
Price $250.00 standard
$125.00 students
Lead Facilitator Dr Adam Siade (University of Western Australia) and Dr Jeremy White (Intera Inc.)
Description

Models are widely used to assess groundwater management strategies; however, uncertainty in model properties and conceptualisation plague their ability to make reliable predictions. While a number of uncertainty quantification methods are available to aid in decision support, groundwater models often suffer from high parameter dimensions and long CPU run-times, rendering most of these methods impractical. This workshop will focus on recent ensemble-based methods that show great promise in overcoming these limitations. Background theory behind ensemble methods will be presented along with a series of exercises and real-world case studies. Attendees will gain experience with the iterative ensemble smoother (IES) via the highly-parallelised model-independent PEST++ software platform.

Workshop 3 – Coastal Hydrogeology
Date Sunday 20 November 2022
Time 1000 – 1600
Price $250.00 standard
$125.00 students
Lead Facilitators Prof. Adrian Werner, Dr Cristina Solórzano-Rivas, and Prof. Brett Harris
Description Attendees will learn fundamental concepts of coastal hydrogeology from leading scientists in this field. The workshop will have two parts: (1) Theory and modelling methods for coastal aquifers (Prof. Adrian Werner and Dr Cristina Solórzano-Rivas; Flinders University), and (2) Field-methods for characterising coastal aquifers (Prof. Brett Harris; Curtin University). Desktop approaches to the investigation of coastal aquifers will include simple, first-order methods (e.g., analytical approaches) and numerical modelling using MODFLOW-6 through the USGS graphical user interface ModelMuse, along with an example of Python scripting to build simple seawater intrusion models. Field-based techniques will include geophysical approaches to the characterisation of coastal sediments and the nature of the freshwater-seawater interface, and geochemical methods for evaluating coastal groundwater processes.
Workshop 4 – Assessing groundwater-dependent ecosystems
Date Sunday 20 November 2022
Time 1000 – 1300
Price Free of charge
Lead Facilitators Dr Andrew Boulton, Dr Tanya Doody, Dr Jodie Pritchard, Dr Peter Hancock.
Description

Groundwater-dependent ecosystems (GDEs) are ecosystems whose species and ecological processes rely on groundwater, either entirely or occasionally. Although subterranean, aquatic and terrestrial GDEs are widespread in Australia, they are seldom adequately considered in environmental impact assessments. Therefore, the Independent Expert Scientific Committee on Coal Seam Gas and Large Coal Mining Development (IESC) has commissioned an Explanatory Note (EN) on Assessing groundwater-dependent ecosystems to help proponents address this need. The EN outlines a logical framework for assessing potential impacts to GDEs and presents useful tools and methods for describing the distribution, condition and groundwater-dependence of diverse GDEs.

This interactive workshop will be presented by the EN authors Tanya Doody and Jodie Pritchard (CSIRO) and Peter Hancock (Eco Logical Australia), facilitated by IESC member Andrew Boulton. After briefly reviewing the main points in the EN, they will demonstrate the various tools and methods, illustrated by worked examples to show how to interpret results and acknowledge constraints.
