The purpose of this study is to perform simulation studies for a specific coal bed methane reservoir. First, the theory and reservoir engineering aspects of coal bed methane reservoirs, such as dual porosity concept, permeability characteristics of CBM reservoirs and...
-
A method integrating geochemical and petrographic analysis, reservoir engineering diagnosis, geophysical data and production characteristics has been developed, and used to determine the initial permeability of coal seam on a metre by metre scale. This overcomes the constraint of conventional...
-
In this study, a nodule structure model was developed based on the nucleation and growth and dual mode sorption model to gain a comprehensive understanding of the plasticisation phenomenon and to link the bridge between membrane formation mechanisms with membrane...

This is the first academic study of well costs and drilling times for Australia's petroleum producing basins, both onshore and offshore. I analyse a substantial database of well times and costs sourced from government databases, industry and over 400 recent...
-
Key petrophysical properties of reservoir sequences are determined by their individual mineral compositions, and are routinely evaluated through the analysis of cores and geophysical well logs. However, mineralogical studies are seldom incorporated in reservoir assessment. The objectives of the study...

Yildiray and his team are exploring how to maximise the extraction of methane from coal beds by injecting CO2. Nitrogen can also be used for this purpose, but - if the coal bed is deep and not going to be...
-
This thesis looks at the techno-economics potential of co-optimising enhanced gas recovery (EGR), enhanced gas condensate recovery (EGCR) and CO2 storage in gas and gas condensate reservoirs. This thesis aims to demonstrate when it is best to inject CO2 for...
-
An integrated approach to optimise hydraulic fracture treatments in reservoirs under complex conditions is developed in this thesis. The optimisation methodology integrates a fracture geometry model which predicts fracture geometry for a given set of treatment parameters, a production model...
-
A major challenge to the accurate evaluation of these reservoirs is accounting for pore scale heterogeneity on multiple scales. This is the topic of this thesis. Conventionally, this micron scale information is achieved either by building stochastic models using 2D...
-
The program will characterise both the hydraulics and chemistry (major anions, cations, stable isotopes) of low permeability strata with the view to better estimating the potential impact of water derived from these strata on groundwater quality and regional-scale aquifer dynamics...
-
Evaluation of the origin, distribution, migration and accumulation of coal seam gas (CSG), contributes to a better understanding of the CO2 storage potential of coals and the production of CH4 from coal seams. This study aimed to analyse the origin...
-
This thesis is aimed to calculate the effective permeability tensor and to simulate the fluid flow in naturally fractured reservoirs. This requires an understanding of the mechanisms of fluid flow in naturally fractured reservoirs and the detailed properties of individual...
-
The new centrifuge facility is one of only two of its kind in the world, providing capability for assessing aquitards. Aquitards, or low permeability sediment or rock that that can store water, are critical to disconnect or partially disconnect flow...
-
Ashri's research will mainly focus on experimentally studying the flow behaviour of gas-water in unconventional shale gas reservoirs and the effect of shale on permeability and productivity. The study will focus on steady-state relative permeability measurements on shale plugs, taking...

This document is a background paper prepared for the Office of the NSW Chief Scientist and Engineer (OCSE), providing information and a discussion about the geological characteristics and history of NSW, with a focus on coal seam gas (CSG) resources...
-
This research focuses on reservoir geomechanics; specifically in the area of wellbore stability for anisotropic formations using both analytical and numerical methods. With the recent emergence of shale gas, simple isotropic models that predict shear and tensile failure will produce...
-
Amin is currently studying the geomechanical behaviour of hydraulic fractures under complex stress states. Using numerical methods (such as FEM and XFEM), the propagation of induced fractures and their interaction both with other fluid-driven and natural fractures are being studied...
-
The purpose of this study is to perform simulation studies for a specific coal bed methane reservoir. Simulation studies were carried out by using the CBM reservoir simulator, SIMED II. Injection/fall-off test pressure data were interpreted based on the pressure...
-
This study addresses the issues of how to integrate different information from various field data sources and construct comprehensive discrete fracture networks for naturally fractured reservoir. The methodology combines several mathematical and artificial intelligent techniques, which include statistics, geostatistics, fuzzy...

This project seeks to: increase biogas yields by redirecting electron flow towards biogas producing microbes using electrochemically active phenazines; understand the molecular mechanism by which phenazines increase biogas yields; and, assess the environmental consequence of phenazine application to coal seam...

The Office of Water Science at the Department of Environment, Australia, is seeking to identify recently commissioned or completed projects researching the potential impacts of coal seam gas (coal bed methane) and coal mining on water resources and water dependent...
-
This research uses micro-computed tomography (uCT) as a means to precisely characterise coal, including the pores and cleats within the coal. Specifically, we are investigating the effects of different mineralisation on coal structure and behaviour by taking 3D images under...

This research is centred in two areas: Firstly hydraulic fracturing, where I'm interested in the optimisation in brittle/ductile shale gas reservoirs, and secondly modelling of multiple fracture propagation in a naturally fractured formation.

Zou's research interest is multiphase flow in porous media and pore-scale reservoir characterization. I study wettability effects on relative permeability using experiments and high resolution micro-CT image.
-
Guo's research interests are in enhanced gas recovery of coal seam gas, coal permeability damage and gas sorption onto/from coal.
