The Norwegian Petroleum Directorate (NPD) has received the Plan for Development and Operation (PDO) for Oseberg Delta phase 2.
The Delta structure is located about 14 kilometres southwest of the Oseberg field centre in the North Sea. The structure is located within the Oseberg area unit, mainly in block 30/9 in production licences 79 and 104, where Statoil is the operator.
Oseberg Delta was previously developed with a subsea template tied in to the Oseberg field centre, and currently has two production wells.
At Oseberg Delta phase 2, Delta will be further developed with two new subsea templates, and the drive mechanism will be changed from depressurisation to partial pressure maintenance based on gas injection. Most of the injected gas will be sold during a later phase.
The two new subsea templates will also be connected to the Oseberg field centre via the existing Delta subsea template. One of the two pipes that currently transport the gas from Tune to Oseberg will be reused to transport gas for injection from Oseberg to Delta.
The project entails investments of just under NOK 8 billion, and the expected production is 4.6 million standard cubic metres (Sm3) of oil and 7.7 billion Sm3 of gas. The oil and gas volumes will appear as increased reserves on Oseberg in the NPD’s next resource accounts, since Oseberg Delta is not considered a separate field. Production from Oseberg Delta phase 2 is scheduled to start in 2015.
The licensees in Oseberg area unit and thus also for the development of Oseberg Delta are Statoil, Petoro, Total E&P Norge AS and ConocoPhillips Skandinavia AS.
