Nigel Allister Anstey, British geophysicist, has made major contributions to seismic exploration, which are the foundations for many of the techniques used in today?s oil and gas exploration. Anstey?s contributions impact every major area of seismic exploration -? from seismic acquisition to seismic processing to interpretation to research. He is the holder of over 50 multinational patents. He is best known by many geoscientists for distilling the geophysical concepts of the seismic method into non-mathematical teachings for seismic interpreters. Anstey?s work in seismic exploration has spanned 7 decades. Upon graduation from the University of Bristol in 1948, he joined Seismograph Service Ltd. and spent five years in the Middle East and the West Indies as an observer on a seismic crew. In 1953, he returned to the UK as a research geophysicist. He wrote a number of seminal papers while at SSL. In 1968, he established the European offices of Seiscom Delta. In 1975, he left the company to focus on teaching and consulting. He has written many books, monographs, and journal articles, as well as being a Distinguished Lecturer for the SEG.
