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 for registration.


On behalf of the Organising Committee we look forward to welcoming you to the seminar in March 2020.
