Scope of Work
West Wandoan 1 was the first exploration well to be drilled in CTSCo’s Greenhouse Gas Exploration Permit EPQ7, which fell under the jurisdiction of the Greenhouse Gas Storage Act (2009). The permit interests EPQ7 are CTSCo Pty Ltd 100%. CTSCo is a 100% owned subsidiary of Xstrata Coal Pty Ltd.
The West Wandoan 1 well is in the Surat Basin, a Jurassic sequence that is around 1260m thick and overlies part of the Triassic age Bowen Basin. The Surat Basin is a sub-basin of the Australian Great Artesian Basin (GAB) and contains fluvial, lacustrine, and marginal marine sediments, and coal- bearing successions.
Key project objectives included:
- Obtaining high quality data and water samples from the coring, logging, and testing program.
- Benchmarking the aquifer water quality in the Hutton Sandstone and Precipice Sandstone.
- Obtaining high quality data and water samples from the coring, logging, and testing program.
