Biography 2023

Lasse Amundsen is Senior Advisor at Equinor and since 1995 has been Adjunct Professor at the Norwegian University of Science and Technology (NTNU). He received a M.Sc. in astrophysics in 1983 and a Ph.D. in physics in 1991 from NTNU. From 1983 to 1985 Amundsen worked with Geophysical Company of Norway (GECO) as a geophysicist and from 1985 to 1991 with IKU Petroleum Research as a research geophysicist. In 1996, he was visiting scientist at Schlumberger Cambridge Research, and in 1997, he was visiting scientist at University of California San Diego (UCSD) Scripps Institution of Oceanography. He was Adjunct Professor, University of Houston, Texas, from 2005 to 2008, and Chief Researcher at Statoil from 2006 to 2014.

He received the Norwegian Geophysical Prize in 2002 and EAGE’s Conrad Schlumberger Award in 2010. He is co-author (with Dr. L Ikelle) of SEG’s Introduction to Petroleum Seismology: 2nd ed. in 2018, and co-author (with Dr M Landrø) of Bivrost’s Introduction to Exploration Geophysics (2018) and From Arrhenius to CO2 Storage with Physics-based Educational Models for Radiation in the Atmosphere (2023). Amundsen is the author of about 200 articles and expanded conference papers, and 100 popular science papers in semi-technical journals. He is a member of SEG, EAGE, Norwegian Physical Society, and The Royal Norwegian Society of Sciences and Letters.

SEG Reginald Fessenden Award 2023

Lasse Amundsen is well known for his work in seabed seismic acquisition and in a variety of areas in seismic and electromagnetic data processing and analysis. He is an adjunct professor at the Norwegian University of Science and Technology and a senior leader at Equinor. He coauthored, along with Luc Ikelle, SEG’s Introduction to Petroleum Seismology, second edition in 2018. In addition, he coauthored, along with Martin Landrø, Bivrost’s Introduction to Exploration Geophysics in 2018 and From Arrhenius to CO2 Storage in 2023. For his many contributions and writings, SEG is pleased to recognize Amundsen with the Reginald Fessenden Award

Biography Citation for the Reginald Fessenden Award

by Johan Robertsson

Lasse Amundsen is one of the most creative scientists in our field. He has inspired generations of researchers in applied geophysics. His research has delivered impact solutions to our industry. Lasse’s work has been driven by curiosity from day one, and that curiosity has not diminished over the years. His passion is not only to understand the science himself, but to teach and inspire others. He has held an adjunct professorship at the Norwegian University of Science and Technology since 1995 while also progressing to senior technical ranks at Equinor. Lasse received the Norwegian Geophysical Prize in 2002 and the European Association of Geoscientists and Engineers’ Conrad Schlumberger Award in 2010 in recognition of outstanding contributions to the scientific and technical advancement of geophysics.

I have known Lasse since 6 November 1996, which was my first day of work in the industry at the Schlumberger Cambridge Research Center, where Lasse spent an industry sabbatical stay. Since then, we have had close collaboration on a range of scientific topics. Lasse is extremely inspiring to work with and brings out the best ideas through collaboration by always questioning and querying findings in a positive and constructive way. Recently, the multisource encoding and decoding (signal apparition) technology coinvented by Lasse has been commercialized by Apparition Geoservices. Apparition allows time and cost savings through faster acquisition or denser sampling on the source side for high-resolution imaging. To date, industry field projects with two to 10 simultaneous sources have been carried out by different vendors across the world.

His research has been taken into technology qualification, implementation, and practice. Lasse and his colleagues designed the first 3D ocean-bottom cable survey over the Statfjord Field offshore Norway, with the purpose of detailed structural P-wave seismic imaging of complex geology from high-fold full-azimuth seismic data. From 1997 to 2004, he led the four-component ocean-bottom seismic (OBS) research processing and development team, demonstrating that the acquisition geometry of the OBS survey gives superior P-wave imaging compared to imaging from conventional streamer seismic data. As a result, Equinor and partners acquired OBS data over a large number of their North Sea fields for improved P-wave imaging. In addition, Lasse has followed several large development projects with external partners.

To many, Lasse is best known as one of the pioneers in seabed seismic acquisition and processing. His 1993 seminal paper in GEOPHYSICS lays the foundation for the up-down deconvolution method for source designature and free-surface demultiple of ocean-bottom node data. The breadth of his work is impressive. He has made major contributions in a variety of areas in seismic and electromagnetic data processing and analysis including modeling, inversion, multiple attenuation, fast 3D tau-p transform, reciprocity, amplitude variation with offset/amplitude variation with angle, deghosting, up/down decomposition, P/S splitting, particle velocity-pressure relationship, 2D to 3D geometrical spreading correction (Abel transform), Q-factor estimation, wavelet estimation, source array signature estimation, Scholte wave attenuation, potential scattering, asymptotic airwave modeling, airwave attenuation, and transverse-electric-transverse-magnetic splitting.

In addition to his technical achievements, Lasse has focused on writing and teaching for the geophysical industry. He has authored three books, 200 articles and expanded conference papers, and 100 science papers. His coauthored book, Introduction to Petroleum Seismology, second edition, is widely used as a reference and as a text in the classroom of many universities. Lasse’s most recent coauthored book, From Arrhenius to CO2 Storage, is a great compilation of articles for anyone interested in understanding the physics and impact of the greenhouse gas effect on our planet.

Lasse’s exceptionally extensive and always innovative and impactful contributions to geophysics, along with his endless interest in novel geophysical ideas, is recognized through the Reginald Fessenden Award
