I thank the sponsors and faculty of the Stanford
Exploration Project (SEP) for technical and financial support given to
me during my studies.  My colleagues at SEP provided invaluable
expertise, resources, and ideas to facilitate all of my work and make
the study of Geophysics engaging and rewarding.

BP provided a data set as yet unique in the world for analysis in this
thesis.  The timely installation of the acquisition system at the
Valhall reservoir in the North Sea provided an excellent opportunity
to test the theory of passive seismic imaging at the kilometer scale.  BP
also gave me the opportunity to work with the data at their Advanced
Imaging research group as an intern for a summer.  While there, Ken
Matson helped flesh out my ideas related to multiple prediction while
I waited for computers to process the enormous passive data volume.
