This project involves research aimed at a cheaper and more effective method to plug and abandon coal seam gas wells and other oil and gas wells. Currently coal seam gas wells and all oil and gas wells are required to be plugged with cement. But this process has limitations because cement is expensive and can require maintenance over time. This research will investigate the use of a naturally occurring clay called bentonite to plug the wells. Bentonite is cheaper and...

CSG companies and regulatory agencies use geological models in decision-making processes regarding the industry. The geological models used by each organisation can vary based on data availability and interpretation and are often focus on specific locations relevant to company operations. This project aims to develop a consistent and unified Surat Basin framework model to provide an improved shared understanding of the geology of the basin. It will provide a regional scale reference model for all users. This model will be...

A technical feasibility study was completed to determine if there is sufficient groundwater quality data available to develop a Water Chemistry Atlas with the capability to address key technical questions regarding regional water quality trends and provide valuable information to government, industry and the community. Key steps included: Developing a test database structure for the Atlas and use of a subset of data from the Office of Groundwater Impact Assessment (OGIA) water quality database for trial purposes. using a range...

The connectivity of coal beds is an important consideration for the economics and feasibility of coal seam gas production. The areal extent of coal is related to the environment of deposition and factors affecting preservation. It is critical to understand the cyclicity within the succession and the lateral shifts in coal forming environments over time The exploratory phase of the CCSG Seismo-Stratigraphic Interpretation pilot project successfully defined a skeleton for a chronostratigraphic framework. The results show differences with previous (pragmatic)...
UQ Business School (University of Queensland)
This broad-scale survey examines stakeholder trust in the Queensland coal seam gas industry. The results of the research will provide high quality, comprehensive insights to inform understanding and practical strategies for enhancing stakeholder trust in the industry. It is the second in a planned series of triennial surveys. The first survey was conducted in 2015 and will provide valuable benchmarking data to build a picture of changing perceptions and attitudes over time. The research provides a rigorous, independent and empirical...

Production of coal seam gas (CSG) wells is associated with producing a significant amount of water. The produced water needs to be removed from the wellbore to reduce the flowing bottom-hole pressure (FBHP) to allow gas to flow into the wellbore. Progressive cavity pumps (PCPs) are widely used for dewatering CSG wells. The PCPs are prone to failure from gas and/or solid interference resulting in high downtime and maintenance costs. The aim of this project is to improve the performance...

The prediction of coal seam gas (CSG) well productivity is heavily dependent on modelling the effective permeabilities of gas and water for the reservoir throughout the production life. Two-phase flow of gas and water in the complex, heterogeneous cleat structure of coal is dependent on many factors which are not well represented in current modelling applications. Consequently, current models typically provide poor predictions of CSG reservoir performance, which limits the effectiveness of these simulations in evaluating well productivity. This project...

Petrophysicists use information about the physical and chemical properties of rocks and rock fluids to develop an understanding of where hydrocarbons and aquifers occur in the subsurface and the way fluids (oil, gas and water) flow through the subsurface system. Reservoir modelling, one of the main techniques used in the identification and evaluation of hydrocarbon reservoirs such as coal seam gas reserves, relies on using geostatistical techniques to estimate the distribution of these properties over large areas. Current techniques, which...

Outdated models still pervade about the hydrogeological nature and connectivity of the Great Artesian Basin (GAB). These concepts give rise to incomplete and in some cases over-simplistic and/or incorrect understanding of the basin. It is critical to revisit and update these concepts with the most recent information now available, and put important new understandings about the workings of the GAB into the public domain. The last 10 years have seen large investment in improving scientific understanding of the GAB’s hydrogeology...

There are significant differences in natural fracture and stress orientations inherent in the geology of each basin. Better understanding of the stress field and its interaction with natural cleats and fractures should improve completion, design and well placement. Our ability to interpret key data is limited by current modelling software. Newer more advanced modelling techniques are emerging that can allow better representation of natural fractures, visualization and integration into analyses to better define design choices This project aims to identify...
