Wintershall has discovered oil in exploration licence F17a in the Dutch North Sea, about 120 km north of Den Helder.
Exploration well F17-10 found a Late Cetaceous Chalk reservoir of good quality containing crude oil. Oil was produced during a production test. The well was spudded on 18 September 2012 with jack-up rig GSP Saturn in a water depth of 44 meters.
The well drilled to a total depth of 1490 meters into the top of a salt dome. Measurements taken in the well indicate the presence of a significant oil column. Preliminary resource estimates indicate a potential of at least 30 million barrels recoverable oil with a more than significant upside.
The well will be plugged and abandoned. Commercial viability of the discovery as well as further upside will need to be confirmed through appraisal drilling planned in 2013.
“It has been awhile since one of our exploration wells has been targeting for oil. Although we are also operating the Kotter and Logger oil fields, for some time now the focus of Winterhsall Noordzee is set around producing gas fields and exploring for gas,” said Gilbert van den Brink, managing director of Wintershall Noorzee B.V.
“The discovery gives us the opportunity to grow our business in the Netherlands and provide a more balanced portfolio in terms of oil and gas. Our challenge now will be to move this discovery from the exploration phase, through appraisal drilling in 2013, to the development phase thereafter. Furthermore we are looking for additional exploration drilling in this area,” he added.
“It would be great if we can add one or two additional oil fields on the map again.”
Wintershall holds a 30% stake in the F17a as operator, alongside EBN B.V. (40%), GDP Suez E&P Nederland B.V. (20%), Rosewood Exploration (5%), and TAQA Offshore B.V. (5%).
