The onshore gas industry in Queensland represents an approximately $80 billion investment whose export output, liquid natural gas (LNG), is flowing into an uncertain market. Given the high onshore gas unit development costs, in part due to the large numbers of wells required to access the permeability networks, marginal changes in the underlying cost structure can make significant changes to the profitability of these developments. Early identification of lessons learnt from the first stage of developments can improve standard operating...

Pressure dependent permeability (PDP) and stress dependent permeability (SDP) behaviour have been exhibited in Surat and Bowen Basin coal measures. Anecdotal and purported evidence from some areas indicates that this is generally a function of coals drawdown rates or observed more often in coals with higher permeability anisotropy. This project will define evidenced behaviour in terms of coal properties or variables using data analytics and analytical tools with production. Models will be developed to describe or methods to optimise or...

School of Information Technology and Electrical Engineering (University of Queensland)
This project builds on the database and prototype software tools that were developed in the Water Atlas Feasibility Study undertaken in 2014. This project will enlarge the scope of the Atlas from the pilot sub-region to the full extent of the Surat Basin and the prototype software tools will be refined to improve performance. Additional datasets will be added and new visualisation, analytical and reporting tools will be developed. Protocols for database access, sharing, security and maintenance will also be...
Centre for Coal Seam Gas (University of Queensland)
Rock properties and stress profiles are critical for understanding wellbore stability, fracture propagation and reservoirs dynamic response to dewatering and the subsequent gas extraction. However, sufficient amounts of sample material are commonly not available due to the inherence low core retrieval, as well as to high drilling and sample costs. This affects the quality or calibration of the well log information, resulting in high data uncertainty. The main aim of this project is to determine the rock properties by integrating...

CSG extraction is associated with production of a significant amount of water, which is removed to reduce the flowing bottom-hole pressure (FBHP) to enhance well production. Reducing the FBHP and therefore abandonment pressure (the point where the production of CSG wells is no longer economic) increases the CSG recovery factor. This project aims to develop novel mathematical models to precisely estimate the FBHP in CSG wells to replace the available models in industry simulators, which were designed for conventional wells...

Seismic surveys use reflected sound waves to map underground surfaces and structures. They are regularly used in the resources sector to map oil and gas deposits during the exploration phase. However they have not been used widely in the Queensland CSG industry due to difficulties in negotiating land access for this purpose and because the expected close spacing of CSG wells suggested that there would be minimal benefit from this type of investigation. This project investigated if detailed analysis of...

The CSG industry uses hydraulic fracturing processes to increase permeability in the coal seams in order to increase gas production. The overall aim of this project is to devise new and environmentally sound stimulation technologies capable of increasing the permeability of various coal seam types. Mineral and organic content varies in the coal formations and consequently the composition of the coal can affect the performance of an individual chemical stimulant at different locations. This research will build on previous work...

Key flow properties in CSG / heterogeneous reservoirs are dominated by end-members of property distributions. To properly reproduce the performance of bulk reservoirs needs a new approach. An innovative, new “Research code” has already been developed by the UQ-CCSG consortium. To make this useable every day by industry professional, it needs to be integrated with the most common modelling package (Petrel). This is an involved, complex commercialisation task. The project will also develop trial uses and demonstration data sets. It...

The production of fine solids is a key technical issue affecting CSG wells productivity in Queensland, and leads to 10-15 days production downtime a year. This project aims to develop a completely new approach to control solids production in CSG wellbores using a selective phase-inversion polymer coating that takes advantage of the low permeability of mudrocks to form a protective barrier across clay-rich layers but remains permeable across the gas-producing coal seams. The expected outcomes of the project include (i)...
Centre for Social Responsibility in Mining (University of Queensland)
QGC, Santos, APLNG and Arrow have entered in to the STEM Schools Partnership (SSP), which funds the delivery of science technology, engineering and mathematics (STEM) enrichment programs to schools in the Surat Basin. The SSP aims to stimulate interest in studying STEM subjects at school and increase awareness and knowledge of trade and professional career opportunities in the CSG/LNG industry and associated supply chain. This project aims to establish and pilot a framework to evaluate the effectiveness of the STEM...
