Improving earthquake detection and location using novel signal processing techniques to support carbon sequestration (CS) applications in the offshore Gippsland Basin

The UoM seismology group has been awarded $424,370 by ANLEC R&D to optimise seismic monitoring and establish a natural baseline for seismicity in southeast Australia in support of the commercial-scale carbon sequestration (CS) offshore Gippsland Basin (The CarbonNet Project), for which a demonstration project is currently under development. The outcomes of our research work provide means to assess the security of CS sites before, during, and after injections. This is necessary for managing reservoirs, fulfilling regulatory requirements, and providing assurance to the public. A key element in our research work is developing capabilities to detect and locate earthquakes accurately, and when possible, in near-real time. At present, our workflows are performed manually, which we intend to optimise by automatising detection and location workflows. The intern will test new algorithms that enable us to detect events and measure seismic phase arrival times automatically. With these new algorithms, we intend to lower the minimum magnitude detection threshold significantly, whereby the number of detected events can be increased. For instance, with template matching techniques, we could potentially increase the number of event detections by as much as ten times. The internship opportunity is likely to commence in January 2021.
