PHY2605H1: Advanced Exploration Seismology

Description Seismic exploration methods illuminate the subsurface using elastic waves.  The signals of interest arise from reflection, refraction and scattering of those waves at lithologic and structural boundaries, where abrupt changes in physical rock properties occur.  A sound geological interpretation of seismic signals requires a complete understanding of the pertinent rock types (e.g., Compressional waves velocity, shear wave velocity, density, anisotropy, absorption) and how they relate to specific exploration targets, as well as how they are influenced by stress, temperature, porosity and pore fluid conditions. In this course, we cover topics such as 3D seismic wave propagation in acoustic, elastic and viscoelastic media ; 3D/4D seismic imaging; acquisition, processing and interpretation of 3D seismic data, hardrock seismic exploration, reservoir geophysics and reservoir monitoring.
