Abstract

In the CO2CRC Otway Project, seismic monitoring has evolved from traditional campaign based seismic acquisition towards techniques using continuous seismic acquisition based on permanently deployed sources and receivers. Permanent reservoir monitoring facilitates assurance of safe CO2 storage, while reducing the cost and the environmental impact of geophysical surveillance. Two Surface Orbital Vibrators were deployed in late 2015 to test their capability as permanent sources. After the optimisation of the SOV design in 2016, the existing buried geophone array was utilised to record continuously for several months. In this study, we analyse the data and outline a methodology for data processing. Promising seismic repeatability is obtained that validates the long-term applicability of the SOVs.

Keywords: Monitoring, geophysical methods, GHGT-14, permanent reservoir monitoring, surface orbital vibrators, repeatability
