Statoil has completed the extensive 2013-2014 exploration programme in the Barents Sea. This represents an all-time high exploration activity and 10% of all exploration wells drilled in the Barents Sea since its opening in 1980.
“This is a unique exploration programme. A commitment of this size and complexity requires geological, technological and organisational muscle, and the data collected are important for the future understanding of the oil and gas potential in the Barents Sea,” says Irene Rummelhoff, senior vice president for exploration on the Norwegian continental shelf.
“It has been argued that the exploration programme has had limited success. Indeed, we have made fewer commercial discoveries than we had hoped for. However, there are a number of things that I take pride in. We have tested a great variety of geological plays in frontier areas and dramatically increased our knowledge with the huge amount of subsurface data we have collected. We have also demonstrated that we can operate in a safe and efficient manner in the remote parts of the Barents Sea.”
The exploration programme started with five wells in the vicinity of Johan Castberg. These wells were critical to clarify the oil potential in the area in order to plan the development of the Johan Castberg field.The oil discovery in Drivis will be developed as a part of the Johan Castberg project.
The three wells drilled in the Hoop area during the summer allowed to build important knowledge of this huge frontier area of the Barents Sea. We have confirmed a working petroleum system in Hoop, but need to work further to understand the migration and where the oil has accumulated.
The Hoop wells were the northernmost wells ever drilled on the NCS, over 300 kilometres from shore. These wells provided a lot of new learning when it comes to exploring remote northern areas and solving logistical and operational challenges related to it.
Though the wells were drilled during the summer months when ice was several hundred kilometres away, we built important experience through developing an ice management plan which we will bring with us moving forward, not least for the 23rd concession round.
