BAGS Seminar – Biondo Biondi
August 18, 2017 @ 11:00 am - 12:00 pm
Starting the beginning of September 2016, we have been continuously recording seismic data as sensed by a fiberoptic cable placed under Stanford University campus and measured by an OptaSense DAS system. Our array has recorded hundreds of seismic events. We have performed preliminary analysis of some of these events and are building a continuously updating database with all the events recorded by the array. We are using ambient (mostly anthropogenic) noise to perform interferometry and to estimate and monitor subsurface properties under the array. Finally, we recorded an active seismic survey with multi-component nodes placed on the top of one of the sides of the DAS array. In my talk, I will show some results of our data analysis and discuss future plans for the project.
Biondo Biondi is Professor of Geophysics at Stanford University. He graduated from Politecnico di Milano in 1984 and received an M.S. (1988) and a Ph.D. (1990) in Geophysics from Stanford. He is director of the Stanford Exploration Project (SEP). SEP is an academic consortium whose mission is to develop innovative seismic imaging methodologies and to educate the next generation of leaders in applied seismology. SEP’s activities are supported by about 20 companies involved in Oil & Gas exploration and production. He is also co-director of the Stanford Center for Computational Earth and Environmental Science (CEES). CEES leads the Stanford School of Earth Sciences’ computational-oriented research and educational programs. He has made contributions on several aspects of seismic imaging, ranging from velocity estimation to parallel algorithms for seismic migration. Since the early nineties he has been at the forefront of the development of waveequation imaging and inversion methods. In 2004 the Society of Exploration Geophysicists (SEG) honored Biondo with the Reginald Fessenden Award. In 2006 Biondo published the book “3D Seismic Imaging” that was the first book to introduce the theory of seismic imaging from the 3-D perspective. In 2007 Biondo was the SEG/EAGE Distinguished Short Course Instructor, for which he gave a one-day course in more than 30 cities around the world.
