The Biennial Geophysical Seminar 2020
The Biennial Geophysical Seminar
The three challenges of the oil & gas industry
With rising global demand, highly volatile prices and increasingly stringent environmental regulations, the oil and gas industry faces three major challenges: 1. optimising the performance of its base assets, 2. maintaining cost efficiency, and 3. improving its environmental footprint.
The industry has already been through a tough several years of drastic cost-cutting and re-structuring, but is now more vigorous and adaptive and more resilient to a rapidly changing world than ever. To meet the increasingly difficult task of finding and producing more hydrocarbons we should both learn from past experience as well as trying new technologies and methods.
The biennial geophysical conference is the most traditional of all the geophysical events in Norway and has been organised in Kristiansand since 1975. The Norwegian Petroleum society and the programme committee is pleased to invite you to two days of interesting talks and fruitful network building in Oslo next March.
Special Offer for Young Professionals:
Bring a colleague under 30 for half price! Participant no. 2 or more under the age of 30 from the same employer receives a 50% discount on the conference fee. Contact the project manager email@example.com for registration.
On behalf of the Organising Committee we look forward to welcoming you to the seminar in March 2020.

Marit Stustad Guttormsen
Work history: Euqinor 2012-present, CGG 2002-2012
Education: Master of Science, applied geophysics – University of Oslo (1996-2002)
I am currently a geophysical advisor in WesternGeco in the areas of Ocean Bottom Seismic and multi-component processing. I have worked with Ocean Bottom seismic since 1989, run the first commercial permanent monitoring system project (Foinaven). I have been involved in development of processing as well as acquisition systems for occean bottom seismic. My current focus is on delivering the seismic results faster to make it even more valuable for 4D as well as fully utilize the information in the converted waves for reservoir characterization and fracture characterization.
