The primary exploration target for the well was to prove petroleum in Middle Jurassic reservoir rocks (the Fensfjord formation). The secondary exploration target was also in Middle Jurassic reservoir rocks (the Brent group) and the third exploration target was in the Lower Jurassic (the Cook formation and the Statfjord group).
31/7-1 encountered a gas column of about 18 metres and an oil column of about 21 metres in sandstone in the Middle Jurassic Fensfjord formation. Reservoir quality is good.
Well 31/7-1 A, which delineated the discovery, encountered a gas column of 6 metres and an oil column of 25 metres at levels equivalent to those of the discovery well.
The prospect had been known for a long time but had not been tested because it was thought to be too small.
Exploration Innovation Prize
“The Exploration Innovation Prize will be awarded to a license group, company, team or individual who during the last two years have given a courageous and innovative contribution in exploring for oil and gas on the NCS. The recipient has matured and drilled a prospect that can be defined as high risk and high potential. The prospect must have been drilled, but can be classified as dry, technical discovery or commercial discovery”.
The Programme Committee for the conference NCS Exploration – Recent Discoveries has selected ten worthy candidates amongst wells that were drilled in 2016 or 2017.
“A true wildcat, with very limited well control, but a valid geological concept …
The candidates are (in alphabetical order): Boné (Eni), Brasse (Faroe), Cara (Engie), Filicudi (Lundin), Kayak (Statoil), Koigen Central (Statoil), Korpfjell(Statoil), Salander (Statoil), Zumba (Tullow) and Ørnen (Lundin).
The exploration community is now – until April 2nd, encouraged to vote for their favourite candidate, upon which the programme committee will select three candidates for a final vote.
“The well was drilled successfully up-flank and proved oil and gas that are very likely to be a commercial discovery
The winner of the Exploration Innovation Prize will be announced during the conference dinner May 23.
