StatoilHydro stretches Tune life line
StatoilHydro has announced that the life of the Tune field off Norway has been
extended and gas production increased following a reconstruction of
production to a low-pressure system.
"A relatively limited investment gives us considerable benefits in the
future," said Geir Hovland, project manager for StatoilHydro.
The field has been shut down since 10 April during the replacement of
compressor and gas cooler internals and the installation of two new gas
meters,
Gains from the reconstruction work are estimated at 2.9 billion cubic metres
of gas and 300,000 cubic metres of condensate from the field.
The Tune development consists of subsea installations and is located about 10
kilometres south-west of the Oseberg field centre. The gas produced from
Tune is injected into the Oseberg reservoir.
The field has produced gas and condensate through reservoir de-pressurisation
since start-up in November 2002. During this period the pressure has dropped
from 525 bar to about 125 bar.
Without the reconstruction production would have been shut down when Oseberg
Delta and Tune South came on stream. The rework will mean it is not
necessary to increase the receiving pressure and Tune may remain on stream
longer than previously expected.
In the future the field could produce gas at a pressure as low as 45 bar, and
towards the end of the field life, around 2012, this could drop further to
30 bar.
