Recent geophysical research has made widespread use of depth migration and velocity analysis in our efforts to improve seismic images in structurally complex areas. Such structural exploration problems include the imaging of salt intrusions and faulted structures from offshore Newfoundland, and the delineation of thrust faulted structures from the Alberta foothills. We show that methods such as reverse-time migration and Kirchhoff migration can lead to significant improvements in our knowledge of geological formations. We are increasingly convinced that structural interpretation of intermediate processing results should play an important role in the development of the seismic velocity model for further iterations.

Dr. Larry Lines received the B.Sc. (1971) and M.Sc. (1973) in geophysics from the University of Alberta, and the Ph.D. (1976) in geophysics from the University of British Columbia. In 1976 he joined Amoco Canada where he worked as an exploration geophysicist until 1979 when he transferred to Amoco's Tulsa Research Center. He worked with Amoco . Research until 1993, attaining the rank of research associate. In 1993, Larry was appointed NSERC/Petro-Canada Chair in Applied Seismology at Memorial University of Newfoundland. As a professor at Memorial University, he also serves as Editor of the Canadian Journal of Exploration Geophysics, Assistant Editor of Geophysics, Associate Editor for The Leading Edge, SEG Translations Editor, and an editor for the Journal of Seismic Exploration. With coauthors Schultz and Treitel, he received the Best Paper in Geophysics Award in 1988, and served SEG as the Spring Distinguished Lecturer in 1991. His interests are in geophysical imaging and inversion. Dr. Lines is a member of SEG, CSEG, Sigma Xi, EAEG, GST, and is registered as a Professional Geophysicist in Alberta and Newfoundland, Canada.
