Lundin Energy Norway owns and operates the Edvard Grieg field in the North Sea. The production is around 100.000 barrels of oil equivalents per day and as such, monitoring the reservoir and its behavior is an important activity for the company. Part of this work involves acquisition of high resolution 4D seismic every 2nd year. The 4D data is used to assess the behavior of the reservoir, where water is being injected and oil is extracted and produced. The field is also monitored in order to position and place new infill wells to increase the recovery factor. Basically, extract oil and gas from areas where the data shows that undrained hydrocarbons are still present.
Lundin Energy Norway was just about to engage in such a new 4D ocean bottom seismic survey – as the Covid-19 pandemic hit us all. Per Eivind Dhelie, senior geophysicist, will reflect on how, despite a full lockdown in most of Europe, the company still managed to mobilize and complete a large seismic campaign involving more than 100 people from more than 20 different countries, boarding 4 large vessels in different ports in Europe, under such challenging conditions. “Working in a lean and agile company where people have the freedom and trust to do what is needed”, turned out to be more valuable than that just company visions on a slide. “Exploration by nature is possible when it runs in your veins and is part of your DNA”.
Per Eivind Dhelie
Per Eivind Dhelie received a Civil Engineering degree in petroleum geology and geophysics from the Norwegian University of Science and Technology (NTNU) in 1998. He started working with seismic image processing both offshore and onshore data for Fugro. A few years later he moved to PGS and continued his focus on seismic processing with special emphasis on demultiple and seismic interference. In 2007 he took over the role as Global Manager for the Geophysical Support team, stationed in Houston. In 2010 he became Chief Geophysicist in PGS MultiClient. Three years later, with more than 15 years in the seismic contractor business, he left PGS and started working for Lundin Norway in Oslo. His primary interest is with broadband seismic and 4D as well as seismic source development. He is an active and contributing member of SEG & EAGE.
