IAH NSW Meeting 14 May 2019: Dr Hamid Roshan (UNSW)

IAH NSW is pleased to announce that our next meeting on Tuesday 14 May 2019 features a talk by Dr Hamid Roshan, Senior Lecturer at the UNSW School of Minerals and Energy Resources Engineering.

Physics-based measurement of formation permeability using widely available downhole logging data

Formation permeability is of fundamental importance in many engineering disciplines such as groundwater, petroleum, civil and construction and others as it predominantly controls the flow of fluids in the sediments. The only reliable technique to measure the formation permeability at the moment is to acquire core from the formation during drilling. Such coring operations are however costly and therefore are often avoided. Thus indirect measurements using downhole logging data have been of interest. Unfortunately the techniques developed so far to estimate the permeability of the formation along the borehole are of empirical nature and therefore cannot be extended beyond their measured laboratory values. Needless to say that significant error has been observed when these empirical correlations were used to fit the values out of their measured range.

In a recent attempt in petroleum industry, Stoneley wave has been used to measure the permeability right at the borehole wall however the operation is quire costly and the obtained results are very sensitive to borehole conditions thus reducing the applicability of the method. We, for the first time, propose to use the resistivity logs and inverse modelling of coupled porous media fluid-ion transport to estimate the permeability of the formation with good accuracy and high vertical resolution. This is the first attempt to estimate the permeability from downhole logging data using direct physics based inverse modelling.

IAH NSW Meeting 9 April 2019: Brendan Dimech and Dr Andrew Frost (Bureau of Meteorology)

IAH NSW is pleased to announce that our next meeting on Tuesday 9 April 2019 features talks by Brendan Dimech and Dr Andrew Frost (Bureau of Meteorology).

A presentation on Bureau of Meteorology’s suite of national groundwater products – Brendan Dimech

Brendan is a Hydrogeologist at the Groundwater Unit with the Bureau of Meteorology. He will present the updates to the Bureau’s suite of national groundwater products (bom.gov.au/water/groundwater) including the National Groundwater Information System (a database of spatial information on more than 800 000 bores and their attributes), the Australian Groundwater Explorer (mapping portal for visualising and analysing groundwater data) and the Australian Groundwater Insight (user-friendly map portal with curate spatial maps designed for non-experts). These products are freely available from the Bureau website. Brendan will discuss the latest updates of data from the February 2019 release, how they relate to NSW groundwater users and some future groundwater product developments

An overview of the Bureau of Meteorology’s Landscape Water Balance website and the Australian Water Resources Assessment Model – Dr Andrew Frost

Dr Andrew Frost is a Senior Hydrologist within the Water Resources Modelling Unit. He will present an overview of the Bureau’s Landscape Water Balance website (www.bom.gov.au/water/landscape) and underlying Australian Water Resources Assessment (AWRA-L) Model; detailing outputs, performance and use. The AWRA-L model produces publicly available national gridded estimates of soil moisture, runoff, evapotranspiration and deep drainage from 1911 until yesterday and are used for retrospective studies and for operational purposes. The modelling system has been released as a community modelling system (https://github.com/awracms/awra_cms), enabling application and development by the wider research community. Further planned development includes implementation of flow routing, application at the 1km scale, operational data assimilation, forecasting (1-10 day and seasonal) and hydrological projection products, and comparison and collaboration with other national/global efforts in this space.

Venue: WSP office Level 27, 680 George Street, Sydney

IAH NSW Meeting 27 November 2018: Dr Jennifer Stauber, NCGRT Distinguished Lecture Series

IAH NSW is pleased to announce that our next meeting features the 2018 NCGRT Distinguished Lecture Series talk by Dr Jennifer Stauber, Chief Research Scientist, CSIRO Land & Water, entitled Groundwater Quality: An Ecotoxicology Perspective.

Dr Stauber is a Chief Research Scientist at the Centre for Environmental Contaminants Research, CSIRO Land and Water in Sydney and a fellow of the Australian Academy of Technological Sciences and Engineering.  She has over 35 years’ research experience and has written over 350 scientific papers and technical reports in the fields of aquatic ecotoxicology and human toxicology.

Jenny has chaired and served as expert ecotoxicologist on several World Health Organisation review boards, together with the NSW EPA Board and a large number of expert advisory panels to the Australian government on areas as diverse as contaminants, reef water quality, uranium mining, coal seam gas, hazardous waste, chemicals risk assessment and water quality guidelines.  She is a member of Australia’s Independent Expert Scientific Committee on Coal Seam Gas and Large Coal Mining Development which advises the Commonwealth Minister on all water-related aspects of coal seam gas.

From 2008 to 2014 Jenny was Deputy Chief and then Acting Chief of CSIRO Land and Water. From 2006-2008 she was a Visiting Professor in the Department of Biology and Chemistry at City University, Hong Kong. In 2006 she was a joint winner of Australia’s Eureka Prize for Water Research for research into the assessment and regulation of contaminated sediments.
