Objective: Determine the residual CO2 saturation, (Sgr)
Five independent measurement approaches to determining residual trapping:
110 tonnes CO2 captured from Callide Oxyfuel Services Pty Ltd’s (COPL) Callide A Oxyfuel project in Queensland was stored at Otway. Some small amounts of carbon dioxide were also stored containing impurities commonly found in carbon dioxide collected from coal fired power plants. The impurities were found to not affect the storage capacity or the formation fluid of the geological reservoir.
2C: Spatially track injected CO2 in a saline formation
Otway Stage 2C preliminary results:
The combination of these results, with ongoing regular monitoring through to 2019, will de-risk the injection, monitoring and trapping of CO2 in a saline formation giving confidence to technology users and regulators.
