SEG is awarding Honorary Membership to Virgil Bardan for his distinguished contributions to exploration geophysics. Bardan is a senior geophysicist at Prospectiuni S. A. and at the Geodynamical Institute of the Romanian Academy. His scholarly publications span the period from 1973 to 2003 primarily covering diverse topics in seismic acquisition and processing. Bardan was awarded Honorary Membership in EAGE in 2002.

Virgil Bardan is internationally recognized for his contributions to seismic data acquisition and digital data processing related to inversion, sampling, and multiple attenuation. His solid scientific efforts, numerous publications, and erudite presentations at geophysical meetings, in a career that has extended for more than 45 years, have established him as a leader in exploration geophysics, especially in reflection seismic methods. Bardan, born on 4 November 1939 in Strehaia-Mehedinti, has lived all his life in Romania, a country with a long history (more than 150 years) of petroleum exploration and production. Before World War II, Romania was the uncontested leader in European oil production and has repeatedly served as experimental ground for many geophysical methods. It is in this fertile ground for resource exploration that Virgil’s passion for the mathematical aspect of geophysics and for seismic data processing was anchored.
Bardan received a master’s in electronic engineering (1961) at the Polytechnic University of Bucharest (PUB) and a master’s in mathematics (1970) at the University of Bucharest (UB). Subsequently, he obtained a Ph.D. in applied mathematics (1978) from UB and a Ph.D. in data processing (1992) from PUB. He worked for more than four decades (1961–2004) for the Prospectiuni S. A. Bucharest, the leading national geophysics company, in acquisition/processing of geophysical data, research and field work, and oil and gas exploration.
During the same period, he was a part-time professor at PUB and a consultant for Western Geophysical. In 1991–2006, he was a part-time professor/invited lecturer at PUB and since 2004 he has been a part-time research geophysicist at the Geodynamical Institute Sabba S. Stefanescu of the Romanian Academy. Retirement from a profession he profoundly loves was never an option!
Bardan is a theoretician as well as practitioner, a rare combination of scientific talent and professional skill. He has published more than 80 papers in geophysical periodicals and presented numerous papers at international conferences. His papers have appeared in GEOPHYSICS, Geophysical Prospecting, First Break, Journal of Imaging Systems and Technology, and various Romanian journals. His contributions to the development of the geophysical inversion theory, highly appreciated internationally, have important applications in many areas—including dynamic predictive deconvolution, vibroseis deconvolution, migration, and dip moveout. His contributions to sampling and interpolation are also significant to the foundations of modern seismic data acquisition and processing. Among his other publications are noteworthy contributions to trace interpolation for spatially aliased seismic data; sampling 2D seismic data to evaluate linear Radon transforms; hexagonal sampling and hexagonal binning in 3D seismic data acquisition; and dealiasing of common midpoint gathers and constant-offset sections. Other important works treat the time-space domain, and a poststack, multiple elimination method that uses an eigen-image technique.
Bardan is an esteemed and inspiring educator. He has published in several volumes that are used as university texts and has taught numerous generations of young Romanian geophysicists. Processing of Geophysical Signal (published in 2004 in Romanian) has proved an extremely useful monograph for graduate students and professionals.
Bardan is an intense, dedicated geophysicist with a high sense of teamwork. He is a modest, communicative colleague always ready to share his expertise. He has received seven Romanian patents. His honors include the Gheorghe Murgoci Award (1983) from the Romanian Academy and EAGE Honorary Membership (2002).
He is truly an ambassador of the Romanian school of geophysics that has produced through the years highly educated professionals who work all over the world. We, his colleagues, are very proud of Virgil’s achievements—past, present, and future (he continues to publish and present recent research at meetings). It is only appropriate that he receive SEG Honorary Membership for a lifetime of contributions.
