DEA Norge finds oil and gas in southern Barents Sea


DEA Norge has encountered an oil and gas discovery in PL609, north of the Snøhvit field.

Earlier this year, the licence partnership successfully created an appraisal well at the Alta discovery.  

The drilling campaign of exploration well 7220/6-2 R in the Barents Sea has led to a discovery of oil and gas.

DEA Norge exploration manager Svend Erik Pettersson said: “We are satisfied to participate in yet another discovery in the Barents Sea, and this shows that this region continues to be attractive for DEA.”

The Neiden well 7220/6-2 R forms a part of the ongoing drilling campaign in the Barents Sea.

DEA Norge serves as a partner in three wells of this campaign.

"The rig will now continue to the Fillicudi prospect south-west of Neiden for the last well in this campaign."

Previously, the drilling rig Leiv Eiriksson developed an appraisal well on the eastern flank of the Alta discovery before Neiden.

Petterson said: “The rig will now continue to the Fillicudi prospect south-west of Neiden for the last well in this campaign.

“The Neiden re-entry well encountered oil and gas bearing intervals in good quality carbonate reservoirs of Permian age. This discovery warrants further evaluation of the greater Neiden area with a view to potentially unlock additional volumes in yet undrilled structures.”

Well 7220/6-2 R serves as a continuation of well 7220/6-2 that was temporarily abandoned in November 2015.

Located nearly 60km from the Alta oil and gas discovery, the well is almost 200km from the shore.

The Neiden well had two main objectives, which were to find petroleum in sandstones of the Middle Triassic Snadd Formation, as well as in the carbonates of the Permian to Carboniferous aged Ørn Formation.

In the Ørn Formation, the well found a total hydrocarbon column of 31m with a 10m gas cap above 21m of oil.

The initial estimation stated that the discovery hosts between 19 million and 44 million barrel of recoverable oil, and between one and two billion standard cubic metres of recoverable gas. 

Although the well was not production tested, it carried out an extensive data collection programme that included conventional coring and fluid sampling.

The well is the sixth in PL609, which was awarded following the 21st concession round of 2011.

The campaign drilled to a total depth of 1,293m below mean sea level in basement rock that has water depth of 387m. It is now being permanently plugged and abandoned.

DEA Norge holds a 30% interest in the licence. The remaining stake is held by Idemitsu Petroleum Norge (30%) and Lundin Norway (40%), which also serves as the operator.
