This course will consist of 4 4-hour sessions, 10 AM – 2 PM

It will be done live on the Internet, using connections through Go-To-Meeting.

Each student will be given Internet access to the full live presentation, with an opportunity for interaction with the instructors and other students, while viewing the same Power Point Presentations (with audio) that are shown to other attendees.

Course Description
 
All rock masses are seismically anisotropic, but we often ignore this in our seismic acquisition, processing, and interpretation. The anisotropy nonetheless does affect our data, in ways that limit the effectiveness with which we can use it, if we ignore it. In this short course, we will understand why this inconsistency between reality and practice has been so successful in the past, and why it will be less successful in the future, as we acquire better seismic data (especially including vector seismic data), and hold correspondingly higher expectations of it. We will further understand how we can modify our practice so as to more fully realize the potential inherent in our data, through algorithms which recognize the fact of seismic anisotropy. The course is accompanied by numerous class exercises, presented in  Excel (.xls) format.
