Application of Distributing Acoustic Sensing in Geoscience and Beyond

20 November | 7:00 AM Central Time

At the Center for Geophysical Forecasting (CGF) at NTNU we have focused on acquisition and analysis of DAS (distributed acoustic sensing) data for several years. I will discuss and show various examples of DAS-data and how such data can be utilized for geophysical analysis. On a fiber optic cable between Ny Ålesund and Longyearbyen at Svalbard in the Arctic, we have recorded a large number of whale calls and earthquakes. Examples of how distant storms in the South Atlantic can be observed in an Arctic fjord will be shown. Currently we are investigating if DAS can be used to monitor changes in quickclay during a road construction period in Norway.

From 1989 to 1996, he was employed at IKU Petroleum Research as a research geophysicist and manager. From 1996 to 1998, he worked as a specialist at Statoil’s research center in Trondheim. Since 1998, Landrø has been a professor at the Norwegian University of Science and Technology. He received the Norman Falcon award from EAGE in 2000 and the award for best paper in GEOPHYSICS in 2001. In 2004 he received the Norwegian Geophysical award, and in 2007 Statoil’s researcher prize. He received the SINTEF award for outstanding pedagogical activity in 2009. In 2010 he received the Louis Cagniard award from EAGE and in 2011 the Eni award (New Frontiers in Hydrocarbons). In 2012 he received the Conrad Schlumberger award from EAGE. Landrø’s research interests include seismic inversion, marine seismic acquisition, and 4D and 4C seismic. This includes geophysical monitoring of CO2 storage. In 2014 he received the IOR award from the Norwegian Petroleum Directorate. He is a member of EAGE, SEG, The Norwegian Academy of Technological Sciences and The Royal Norwegian Society of Sciences and Letters. He is currently director at the Centre for Geophysical Forecasting at NTNU.
