When Glitne came on stream in 2001, the intention was for it to produce for 26 months. Twelve years later its final drops of oil are being extracted and it has now been decided to close the field.

Glitne is the story of how important various measures are for extending the lifetime of a field several times over.

According to the plan for development and operation (PDO) in 2001, the expected lifetime was up to three years.

Process and well measures, and the drilling of new wells, are all part of the success story that have made Glitne a fantastic example of extended lifetime and improved oil recovery (IOR).

Now that the decision to close has been taken, we are witnessing the conclusion of an IOR saga that few could have foreseen twelve years ago.

Total production has amounted to 55 million barrels, which is more than double the original estimate.

Statoil drilled new wells on Glitne in 2004, 2005, 2007 and 2012. The final well drilled in 2012 showed the field to be no longer viable.

The decision to close has now been taken and Teekay have received notice of termination of the Petrojarl1 contract. The notice period is six months and there will therefore be full activity during this period.

"As the field's lifetime draws to a close, we are certain that all possible means of recovering its resources have been tried. We are highly satisfied with the efforts made to recover the last remaining drops of oil on this field. Meanwhile it is important that we now set about winding down the field in a sound and professional manner," says senior vice president for operations North Sea west, Jannicke Nilsson.

When a PDO is submitted it must also include plans for the closure of the field. This is now taking place on Glitne. A total of seven wells are to be plugged and the field closed.

There is currently much activity in Statoil, and a great need for operational personnel, so the Glitne employees will get exciting new tasks on other fields.


  • The Glitne oil field is located in blocks 15/5 and 15/6 in the Sleipner area of the North Sea. The field is situated roughly 40 kilometres northwest of Sleipner East at a depth of 110 metres.
  • Glitne began to produce oil on 29 August 2001, after the field was discovered in 1995 and appraised in 1997.
  • The field is operated by the production and storage vessel Petrojarl 1, which is owned by Teekay Petrojarl Production ASA.
  • Glitne is owned by Faroe Petroleum Norge (9.3%), Det norske oljeselskap (10%), Total E&P Norge (21.8%) and Statoil (58.9%).
