Geoscience Australia and CSIRO collected three years of continuous methane and carbon dioxide measurements at the Arcturus station in the Bowen Basin, Australia. The dataset supports a simulation study on the sensitivity of atmospheric techniques for detecting fugitive emissions from a simulated coal seam gas field. The poster presenting these results was delivered at the American Geophysical Union meeting in December 2013.
Use Cases
- Simulating fugitive methane emissions based on well density, production volumes, and field size typical of Australian CSG fields.
- Evaluating the statistical likelihood of detecting fugitive emissions at various emission levels using a single monitoring station.
- Developing a time series model of methane baseline signals to generate alternative realizations for sensitivity analysis.
- Comparing perturbed and baseline methane signal distributions to test for the presence of fugitive emissions.
Strengths
- Three years of continuous methane and carbon dioxide measurements provide a substantial baseline.
- Simulations are based on parameters typical of Australian coal seam gas fields, including well density, production volumes, and field size.
- Analysis includes measures of both detection likelihood and false alarm rate for fugitive emissions.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the Bowen Basin monitoring station.
