The CGF DAS-survey from Svalbard 2020 is mentioned in Science this week in a feature article written by Paul Voosen. The Science article is entitled "Researchers are weaving optical fibers into a low-cost network of seismic sensors that can probe Earth's hidden dynamics", and highlights how CGF researchers last year set a new record for DAS length detecting vibrations 120 km away from the interrogator. Several whale vocalisations were recorded on the DAS fiber. Read more here.

21.11.01 - Visit by MEP Markus Pieper
CGF was pleased to host a visit of Dr. Markus Pieper, Member of the European Parliament for Germany, on Monday 1st November. Dr. Pieper was visiting Trondheim as a part of a visit hosted by Equinor to present an overview of R&D on CCS, renewables and low-carbon hydrogen. Professor Philip Ringrose and Professor Martin Landrø presented an overview of C02 storage research with a focus on emerging geophysical methods, including the latest findings in fibre-optic sensing, that can support future expansion of CCS in a low-emissions society.
21.10.05 - More new arrivals at CGF!
After his Bachelors in Geoscience, Kevin worked for 1.5 years at GEOMAR Kiel and IPG Paris on seismic data from the Mid-Atlatic-Ridge, imaging crustal and upper mantle structures. Afterwards he pursued the IDEA LEAGUE Master in Applied Geophysics at TU Delft, ETH Zürich and RWTH Aachen. Within his Master’s Thesis he used ambient noise correlation techniques to constrain the subsurface reflectivity below NASA’s InSight lander on Mars. His PhD research here at the CGF will be anchored in WP3 and will focus on using DAS for monitoring shallow subsurface properties as a potential tool for landslide forecasting.
Kristoffer graduated with an M.Sc. in geophysics from the University of Bergen in August 2021. The theme of his Master’s thesis was the use of acoustic waves to estimate temperatures in the ocean over large distances. In particular, he worked on forward modelling in the Fram Strait, where the presence of non-geometric arrivals is causing difficulties in analysing the acoustic data. Here a new and efficient modelling technique based on the ray-Born approximation was introduced, which used a GPU to do the computationally-demanding raytracing. At CGF his research will focus on ray tracing and inversion in anisotropic media.
Nick studied his first master’s in Petroleum Geoscience at the University of Aberdeen and then worked as a logging geologist for a year before undertaking a second master’s in Applied Geophysics as part of the IDEA League programme between TU Delft, ETH Zurich and RWTH Aachen. His master’s thesis focused on leveraging advances in rotational seismology alongside applying machine learning techniques to efficiently classify and separate different wave-modes from large datasets. His research will focus on multi-physics modelling for in- well monitoring of production and injection wells using fibre-optic data as part of WP3.
One of the major focus areas for CGF is to develop and test methods for different types of geophysical monitoring of nature and the environment and to create innovative products in service of the community. CGF has been working with Indre Fosen municipality to identify a place that is of social interest to conduct research experiments. In connection with the construction of a new road between Sund and Bradden, we thought it might be valuable to drill some test wells and instrument them with geophysical measuring equipment such as hydrophone cables and FO for DAS.
CGF has previously made geophysical measurements over time in shallow wells, and shown that one can measure tube-wave velocities with quite high accuracy. We want to use the same measurement setup for observation and monitoring of any changes in the subsoil in connection with road construction. The first results are now coming through and show that DAS does indeed detect a multitude of signals of interest!
21.09.22 - New arrivals at CGF!
CGF welcomes several new PhD students to its ranks, following a successful recruiting campaign earlier this year, bringing in fresh young energy and ideas to energise our Work Packages.
First up we have Andrea, a geologist from Brazil who has worked in the energy industry in the US, UK and Norway. Andrea has extensive experience in fit-for-purpose reservoir modelling and integrated uncertainty analysis. She developed a keen interest in research and innovation on CO2 storage while working on her Master’s thesis, investigating factors impacting multi-layer plume distributions in CO2 storage reservoirs, followed by involvement in the Northern Lights project while working as a consultant for Equinor in Trondheim. Her research will focus on improving quantification of CO2 migration into the overburden and detection of possible leakage out of the storage complex. Andrea is working with Phil Ringrose in WP 2.
Next we have Franz, a geophysicist with a background in active seismics who became interested in using fibre-optics for seismic monitoring as part of his Master’s thesis. In his PhD work he is interested in registering and monitoring avalanches as well as other geohazard events using Distributed Acoustic Sensing. Franz is working in WP 1.
Kristina studied Applied Physics at Waseda University in Japan, and then graduated with a Masters in Physics at NTNU. Kristina is working on embedding geophysical activity sensors in optical data communication systems. The project aims to develop a sensor that can be integrated into an optical fibre infrastructure that can differentiate geophysical from other activities, such as manufacturing. Using the optical fibre itself as a sensing element could allow us to operate at distances beyond current DAS limitations. Kristina is excited to be working as a PhD candidate at CGF as part of WP1 and is looking forward to contributing to accurate monitoring and forecasting of the Earth.
Finally (for the moment) we welcome Ricardo, a geophysicist with degrees from Universidad Simón Bolívar (USB) in Venezuela and NTNU in Norway. Ricardo is passionate about quantitative seismic interpretation and rock physics, and he has been working for the last 3 years at CGG in the UK, doing both seismic data processing and velocity model building. During his research project, he plans to combine his experience in seismics with plume dynamical models, to improve the detection and monitoring of CO2 injected into a reservoir as part of WP2.
