Abstract
The CO2CRC Otway Project is Australia's first demonstration of geological storage of CO2 within deep underground reservoirs. The project has undergone many phases of implementation and the latest work program, Phase 2C, is aimed at injecting between 10,000 and 30,000 tonnes of CO2 into the saline Paraatte Formation located around 1,400m below surface. One of the key measures of success for Phase 2C is successful seismic detection of the injected gas stream. The geophysics team from Curtin University of Technology have previously conducted three 3D surface seismic surveys, and numerous smaller experiments, at the Otway CO2 re-injection site. These tests were completed during Phase 1 of the Otway Project whereby an (80-20%) CO2-CH4 gas mixture was re-injected into the depleted Warre-C gas reservoir. The feasibility of seismic monitoring of the CO2-CH4 gas mixture injected into the Paraatte Formation is expected to be improved over the Warre-C reservoir due to the increased fluid property contrast between brine and the CO2-CH4 mixture and the shallower depth of the reservoir. A comprehensive desktop feasibility study has been completed by the Curtin/CSIRO geophysics team to assess the probability of successful seismic detection and the preliminary results are encouraging. A Seismic Assurance Review workshop was completed incorporating seismic expertise from both academia and industry to assess the risk of unsuccessful seismic detection. The workshop was held on the 3rd and 4th of November, 2011, at Curtin University of Technology.
