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.

21.04.21 - CGF is pleased to announce a new Partner, Magseis Fairfield

Magseis Fairfield has applied and been approved as partners in the CGF, bringing an exciting new set of competencies and commitment to the vision of enabling the energy transition.

“We recognize that geophysical experience from the oil and gas industry will play a key role in facilitating the energy transition, and see this as a great opportunity to collaborate with our customers and other partners to further develop solutions within the renewables space.”, says CEO, Carel Hooijkaas.

20.12.14 - Official opening of the CGF

The official opening of the CGF was held on 14th December 2020, hosted by Ingrid Schjølberg (Dean Faculty of Information Technology and Electrical Engineering) with guests of honour Rector NTNU Anne Borg (seen here cutting the ribbon) and State Secretary Tony Christian Tiller, who participated virtually.  The centre will be hosted in the historic old building for electro-engineering at Gløshaugen, designed by the reknown architect Bredo Greve and built in 1910.

21.04.08 - Presentation on using polarisation data from FO network

Steinar Bjørnstad from Tampnet gave an inspiring presentation on the potential for "Using State of Polarisation data from fibre-optical communication systems for monitoring purposes". This is a new DAS technique which does not require the fibre to be dark and which can relatively easily be installed on existing fibres worldwide to provide massively extensive sensing coverage of the Earth's low-frequency activity.

21.03.11 - Webinar on AI in HPC by Prof. Anne Elster

This talk will focus on how AI techniques can be used in the development of HPC environments and tools. As HPC systems become more heterogeneous by adding GPUs and other devices for performance and energy efficiency, they also become more complex to write and optimise the HPC applications for.  For example, both CPU and GOUs have several types of memories and caches that codes need to be optimised for. We show how AI techniques can help us pick among 10's of thousands of parameters one ends up needing to optimise for the best possible performance of some given complex applications. Ideas for future opportunities will also be discussed.

PhD positions for the future

The CGF will be issuing invitations to apply for funded PhD positions from time to time.  Being a strongly interdisciplinary centre, we are looking for entrepreneurial students with a wide variety of interests and backgrounds, from electronic engineering to fibre optics, from geophysics to acoustic wave propagation modellers, from heterogeneous computing to statistical and data scientists.  Successful applicants will work at the CGF premises at NTNU in Trondheim as part of our international team of key researchers. The CGF PhD research fellowships are hosted by several departments at NTNU: Computer Science, Electronic Systems, Geoscience and Petroleum and Mathematical Sciences. The Centre has close contact with industry partners as well as research partners NORSAR and Jamstec in Japan.  

PhD students will use and develop advanced models and methods for combining diverse geophysical data to effectively monitor the earth. PhD students will be involved in the planning of new surveys and the acquisition of valuable geophysical information to improve forecasts and provide important decision support for the various application domains of the CGF.  

The CGF is developing novel methods for the cost-effective use of fibre optic cables, creating Distributed Acoustic Sensing (DAS) systems for Earth monitoring. Such DAS data complement traditional geophysical data sources such as seismic waveform measurements, electromagnetic data, and geomodelling information.  

To extract the important variables from massive spatio-temporal geophysical data, the CGF will work on heterogeneous platform computing and AI-based approaches for feature extraction, enabling efficient monitoring and early warning systems in the various geosciences applications.  

PhD research work will be led by supervisors with strong scientific profiles in the specific disciplines at the CGF.

The CGF is determined to deliver research-based innovation, and it will strongly stimulate PhD candidates to create and develop innovative ideas into business potential both for the Centre partners as well as in spin-off companies. The key innovation areas of the CGF are in CCS management, hydrocarbon production monitoring and geohazards monitoring and forecasting.
