- •
The paper presents results of modelling examination of the seismic monitoring strategy for Stage 2C of the Otway project of the CO2CRC Ltd.
- •
A workflow for building a detailed seismic model was developed and justified.
- •
4D seismic synthetic datasets were created using FDTD approach for an actual field acquisition geometry.
- •
An analysis of the synthetic datasets confirmed detectability of the small CO2 plume in the presence of random bandlimited time-lapse noise.
