Gygrid Oil Discovery Could Extend Njord's Commercial Life

Oil has been discovered by StatoilHydro in the Gygrid prospect about 20 kilometers northeast of Njord in the southern part of the Norwegian Sea.

"It's very positive that we've now found oil in the Halten Bank area," commented Rune Adolfsen, operations vice president for Njord.

"Light and fine crude from Gygrid could be phased into Njord and extend the commercial life of a field now in its tail production phase.

"I'm very pleased with the exploration commitment in this area close to existing infrastructure, and that the work is yielding results."

Made by an exploration and an appraisal well, the discovery contains 20-30 million barrels of recoverable oil. Neither well was formation tested, but extensive data and cores were gathered.

"It's interesting that we've found oil in the same area where we encountered gas last year in Galtvort," said Sivert Jorgenvag, head of infrastructure-led exploration on the Halten Bank.

"Results from these two finds will be used in our further work with the prospectivity of this license."

The wells were drilled from the West Alpha semisub, which will now be moved to production license 407 in the North Sea to drill appraisal well 17/12-4 for operator BG Norge AS.

  • Drilled as a sidetrack from the exploration well, the appraisal confirmed the oil column and delineated the discovery. It also found oil in Middle Jurassic rocks. The well was drilled to a vertical depth of 2,123 meters and terminated in the Lower Jurassic Tilje formation.
  • These wells are the third and fourth in PL 348, where the water depth is 247 meters. They will now be permanently plugged and abandoned.
