Clint W. Frasier and Don Winterstein received the 1990 SEG Best Paper in Geophysics Award for their paper Analysis of conventional and converted mode reflections at Putah Sink, California using three-component data.
Don Winterstein received a B.A. in English from Valparaiso University in 1964, an M.S. in solid state physics from the University of Idaho in 1969, and a Ph.D. in cosmic ray physics from the University of Michigan in 1972. He joined Chevron in 1974, doing geophysical research with Chevron Oil Field Research Co. most of the time since then. His research has focused on processing and interpretation of multicomponent seismic data with emphasis on velocity anisotropy since 1977. In recent years he served as a steering committee chairman of the ARCO Multicomponent Seismic Experiment and as Organizing Committee Chairman of the SEG Summer Workshop on Recording and Processing Vector Wave Field Data.
