The Alpha North gas and condensate structure on Statoil's Sleipner West field in the North Sea began production Oct. 11, just over 24 months after the project was sanctioned.
The development has been brought onstream with one subsea template and four wells.
A 16-in. pipeline transfers the wellstream to the Sleipner T gas treatment installation on Sleipner East for processing. The seabed facility is 18 km northwest of the Sleipner platforms.
"Production from Sleipner West Alpha North represents an important addition to gas supplies from the Sleipner area," Helge Skjold, project manager, says.
The development has been delivered on time and at a cost of NKr2.3 billion, NKr750 million below the original estimate.
Recoverable reserves are estimated at 13 bcm of gas and 32 MMbbl of condensate.
Statoil operates Sleipner West with 49.5% interest. Partners include, ExxonMobil with 32.34%, Total with 9.41%, and Norsk Hydro with 8.85%.
