December 2014

As part of a grant from the Australian Government Australian Renewable Energy Agency (ARENA) researchers Prof. Pavel Bedrikovetski and Dr Zhenjiang You have created a new software module for determining two phase flow (gas and liquid) from geothermal reservoirs. This software is now available to participants in the Australian Geothermal community free of charge.
A description of the software's capability, and application, can be found here. The output will be an executable computer software code compatible with MATLAB, a user guide, and an example of the code's usability and functionality.

Dr Craig O'Neill from Macquarie University presented to the SACGER team a synopsis of the geoscience conference entitled "Interdisciplinary Micro to Macroscale Geomechanics. Geomechanical approach for optimization of unconventional reservoirs" he attended  in November 2013. It was held at the  Houston Geological Society in collaboration with ARMA (American rock mechanics association) . The conference contained four sessions distributed over two days and addressed topics such as: "Play scale geomechanics", "Petrophysical & Geomechanical integration", "Microseismic and geomechanics", and "Engineering & geomechanical integration". Craig presented material to the group illustrating how this information could be applied to future Australian geomechanical related unconventional projects.

The Geophysics research group won The Australian Innovation Challenge this month Dr Stephan Thiel, Postdoctoral Fellow (SACGER) and fellow SACGER geophysicists in the 4D Electrical Earth Imaging group, won the Minerals and Energy category of the competition with their new way  to monitor groundwater

The team  have developed a low-cost, low impact, 'game-changing' approach to assessing the impacts of coal seam gas exploration and production on groundwater. "A viable and sustainable coal seam gas industry will bring domestic energy security, export growth and substantial economic prosperity for Australia. But to do this sustainably we need to address concerns surrounding potential impacts on groundwater aquifers," Dr Thiel says. Extracting gas from coal seams typically involves taking water from the aquifer to allow the gas to flow. Sometimes water is also injected at high pressure to stimulate the coal seam - the process known as fraccing.

The research group at Adelaide has pioneered the technique in a geothermal "frac" operation in South Australia, imaging changes underground as they occur. Instead of mapping fractures, we are mapping groundwater flow, which is much less invasive and lower cost than existing methods such as drilling monitoring wells or using microseismic technologies.

The Australian Innovation Challenge is an annual competition in association with Shell and supported by Innovation Australia, the Federal Government organisation supporting industry innovation.

A project led by Professor Graham Heinson is helping address the unique problems associated with extracting energy from unconventional resources like shale gas, geothermal reservoirs and coal seam gas. The researchers are responding to growing demand from the energy and resources sector for sophisticated three and four-dimensional electromagnetic geophysical imaging for sub-surface resources. Funded by Adelaide Research and Innovation's Commercial Accelerator Scheme, the project will integrate hardware, software and technical expertise to provide a low-cost, low-impact method of detecting where sub-surface fluids connect.

Currently, sub-surface changes during exploration and development are monitored either by drilling observation wells or by using microseismic techniques which rely on detection of small ruptures in rocks. Microseismic techniques can lead to ambiguous results and they also require an observation well to be drilled - this may not always be feasible and can add considerable expense to a project. Electromagnetic techniques are amongst the few methods available that can estimate the direction and distance of sub-surface fluid penetration in natural fracture networks without the need for drilling of additional boreholes.

$1.25 million to tackle geothermal challenge
The University of Adelaide has been awarded $1.25 million to lead research into one of the geothermal industry's biggest technical challenges. Supported by the Australian Government through the Australian Renewable Energy Agency's (ARENA) Emerging Renewables Program, the two-year research project will investigate how the industry can reliably produce economic flow rates from geothermal wells.

The research will be led by the South Australian Centre for Geothermal Energy Research (SACGER), part of the University's Institute for Mineral and Energy Resources, in collaboration with CSIRO and partnered by South Australia's Department for Manufacturing, Innovation, Trade, Resources and Energy and geothermal companies Panax Geothermal Limited and Geodynamics Ltd, with total investment of $3.5 million.

SACGER Director and Chief Investigator, Professor Martin Hand, said this research would have significant implications for the geothermal potential of sedimentary basins (Hot Sedimentary Aquifers (HSA)) in Australia and the development of a "near zero" emission energy industry. "Tapping the full potential of this energy source, however, requires that we gain a much better understanding of natural and engineered geothermal systems both within sedimentary basins and the rocks underneath them."South Australia is home to Australia's most advanced geothermal energy projects, with around 30 km of drilling targeting both deep fractured rock and high temperature sedimentary systems. "But predicting permeability and well productivity ahead of drilling in order to generate the required economic fluid flow rates is the most significant technical challenge confronting the Australian geothermal industry."

The project, "Reservoir Quality in Sedimentary Geothermal Resources, will evaluate why the fluid flow rates from Australia's only two geothermal wells in hot sedimentary aquifer reservoirs - Celsius-1 in the Cooper-Eromanga Basin and Salamander-1 in the Otway Basin - have been significantly lower than expected. The researchers aim to determine the causes of the low flow rates and how to evaluate reservoir quality before drilling. They also hope to identify better geothermal targets, devise remediation strategies to reverse causes of low flows and develop mitigation strategies for future geothermal drilling.

Grant to Assist Geothermal Exploration. The Australian Government has awarded a $1.9 million grant to National ICT Australia Ltd's (NICTA) $5 million project to provide enhanced data for targeted geothermal exploration as part of the Australian Centre for Renewable Energy (ACRE) Emerging Renewables Program. NICTA is looking to find better, automated ways to define geothermal targets, using machine learning techniques and adata analytics instead of drills.

The ACRE initiative, Data Fusion and Machine Learning for Geothermal Target Exploration and Characterisation, is a two-year, $5 million dollar program. The ACRE Emerging Renewables Program will fund $1.9 million of this total. NICTA said it would work closely with the School of Information Technologies at the University of Sydney to develop machine learning algorithms, and the Schools of Earth Science at the Australian National University, University of Melbourne and University of Adelaide to apply these methods to the problem of geothermal target characterisation and exploration.

The project teams will also work with ASX-listed geothermal exploration and development companies Geodynamics and Petratherm, as well as GeoScience Australia and the South Australian Department of Manufacturing, Innovation Trade Resources and Energy. Read more.

Better understanding of scaling in geothermal systems through new research facility
Dr Yung Ngothai, Professor Allan Pring, Dr Joel Brugger and Associate Professor Brian O'Neil

This work involves corrosion and scaling in Enhanced Geothermal Systems (EGS) and follows on from a pilot study using a hydrothermal cell at representative reservoir temperatures (100-250°C) to study fluid-rockinteractions in geothermal reservoirs.

However, the pilot study cell operated at pressures well below pressures (~ 300 bars) typical of EGS reservoirs in South Australia Researchers have built and tested a high-pressure flow-through cell which allows probing of fluid-rock interactions at temperatures up to 250°C and pressures of up to 600 bars. These conditions realistically simulate geothermal reservoir conditions. This flow-through rig has worked successfully in the laboratory and has also been used for in-situ experiments on one of the neutron diffraction beam lines on the Open Pool Australian Lightwater reactor at Lucas Heights. These experiments allow the dissolution and precipitation process to be studied in real time. In collaboration with TRaX researchers, a CAMECA SX-5 electron probe has been purchased through Australian Research Council funding. South Australian Premiers Science Research funds have been used for a trace element mapping facility to better characterise the outcomes of dissolution and precipitation experiments.
