报告摘要
I investigate waves and oscillations in a coupled conduit-crack system and aspire to address challenges faced by both volcanology and oil industry. I perform numerical simulations in 2D and 3D to capture rich resonant modes in such systems, understand the oscillation physics of distinct modes, and identify general controls on their periods and decay characteristics, such as finite crack length, width, crack non-planarity, conduit geometry, fluid viscosity, buoyancy, etc. I establish the link between physical parameters in the coupled system with observables, such as downhole pressure data in oil wells and broadband seismic data on Earth’s surface, and develop inversion procedures to obtain the optimal parameters that best explain observations.
