Short time-lapse seismic repeatability test, CO2CRC Otway Project, Victoria, Australia
MetadataShow full item record
High seismic repeatability is critical to the monitoring program of the Naylor Field because of the small time-lapse effect related to CO2 injection into depleted gas reservoir (Naylor). To be able to obtain reliable seismic from a time-lapse seismic survey, the repeatability of the time-lapse survey must be determined. This can be achieved by performing zero-time repeatability tests through the acquisition and reacquisition of data in the same area before any changes occur in the reservoir. By comparing the analysis of multiple repeated pre-stack 2D surface seismic and VSP data, differences maybe established to minimize near-surface system effects.
