The Norwegian Minister of Petroleum and Energy approved yesterday the Plan for Development and Operation (PDO) of West Flank 2.
The PDO, which had been submitted in December last year, regards the first of three planned phases for the development of the remaining reserves 5.6 miles from the Oseberg field centre, in the northern part of the North Sea.
“When Oseberg West Flank 2 starts producing in 2018, it will represent a new concept on the Norwegian shelf”, the Norwegian Petroleum Directorate (NPD) said in a statement.
Norwegian Shelf Boasts New Development Concept
The project aims to extend the life of the Oserberg field and will involve the premiere of unmanned wellhead platforms in the area. According to the NPD, these “may be relevant for future developments” and should be considered more often as an alternative to subsea developments.
This type of unmanned wellhead facility “will have no process equipment, living quarters, drilling facilities or helicopter deck”, NPD explained.
The wells on the Oseberg field, which has been in production since 1988, will be drilled using a mobile drilling unit, while maintenance work will be undertaken using “a support vessel with adapted gangway drawing up alongside the platform”.
An Investment Of £696.2 m
According to estimates by operator Statoil and partners Petoro, Total and ConocoPhillips, this development represents an investment of 8.2 billion NOK (£696.2 million), which will allow for the production of approximately 110 million barrels of oil equivalent.
The wellhead facility will be composed by ten well slots, out of which two will be used to inject gas to increase oil recovery.
As well as this, two production wells will be drilled from an existing subsea template on the West Flank, while further injection will take place using a new pipeline.
Although this concept is brand new on the Norwegian shelf, it has already been used on the Danish ad Dutch shelves.Last updated on 09:27AM - 16/06/16
