For a number of years CSIRO has been carrying out research, development and application projects on CSG reservoir characterisation in the areas of geological/rock framework, stress, geologic structures, gas content and composition, coal characterisation, permeability, hydrology and water chemistry.
The overarching objective is to improve evaluation of CSG resources and its production using specialist expertise and techniques for integrated resource characterisation.
Research and development priorities include the assessment of:
- reservoir compartmentalisation relative to geologic structures and in situ stress
variations in gas content and coal composition, including the causes for variation
permeability behaviour during gas desorption and pressure drawdown
the effects of coal properties on reservoir characteristics and resource delineation
the role of microbial gas generation on the resource.
