OSLO, Norway – The Norwegian Petroleum Directorate (NPD) has received Statoil’s plan for development and operation (PDO) for Oseberg Delta Phase 2 in the North Sea.

The Delta structure is 14 km (8.7 mi) southwest of the Oseberg field center and within the Oseberg area unit, mainly in block 30/9 in production licenses 79 and 104.

Oseberg Delta was first developed with a subsea template tied in to the field center, and currently has two production wells.  

Phase 2 involves adding two new subsea templates, with the reservoir drive mechanism altered from depressurization to partial pressure maintenance based on gas injection. Most of the injected gas will be sold at a later time.

The two new templates will connect to the field center via the existing Delta subsea template. One of the two pipelines that currently transport the gas from Tune to Oseberg will be re-deployed to transport gas for injection from Oseberg to Delta.

NPD estimates investments of just under NOK 8 billion ($1.3 billion), with production of 4.6 MMcm of oil and 7.7 bcm of gas. Start-up is slated for 2015. Other licensees in Oseberg area unit are Petoro, Total E&P Norge, and ConocoPhillips Skandinavia.

In the Norwegian sector of the Barents Sea, NPD has authorized Lundin Norway to use of the semisubmersibleTransocean Arctic to drill its first wildcat well on license PL492. The license, awarded under Norway’s APA 2007 round, comprises parts of blocks 7120/1 and 7120/2.

Petroleum Safety Authority (PSA) Norway has approved Statoil’s request to use theTransocean Spitsbergen for production drilling and completion on the Skuld field in PL128, in 343-360 m (1,125-1,181 ft) of water. Drilling is expected to start in mid-July and last around eight months.

Statoil additionally has PSA consent for use of theWest Epsilon for production drilling of well 15/3-A-14 on the Gudrun field in the North Sea, in 109 m (358 ft) of water. The 20-day program is expected to begin next month.
