Course Objectives

This course presents the fundamentals of seismic attenuation in the context of hydrocarbon exploration, where anisotropy and poroelasticity play an essential role. The emphasis is on geophysical applications for oil exploration, but researchers in the fields of earthquake seismology and material science may also find the material useful. Moreover, the course illustrates the use of seismic modeling, including applications mainly in the field of geophysical prospecting.
