UPDATE 1-Statoil to unveil size of giant oil find in 2 weeks
* N.Sea find could be 3rd biggest ever made off NorwayBy Henrik StolenOSLO, Oct 18 (Reuters) - Norway’s Statoil said a
major oil find, described as a “giant” by a partner last month
and seen as giving new life to fading North Sea production, was
significant and it would aim to give a more precise estimate of
the size within two weeks.Statoil said that an appraisal well in its Aldous Major
South structure showed a “significant” amount of oil.The discovery has revived prospects for the North Sea, a
mature oil region largely written off by the oil majors as a
promising area for new exploration.Oil minnow Lundin Petroleum said last month that
Avaldsnes/Aldous Major South, which could already be the biggest
oil find made so far this year, may hold 1.2 billion to 2.6
billion barrels of oil equivalent (boe).At 2.6 billion barrels, it would be the third-largest made on
the Norwegian shelf, surpassed only by the Statfjord and Ekofisk
fields which kicked off Norway’s oil era in the 1970s, each
field with more than 3 billion barrels.Statoil, one of Lundin’s partners in the find, declined at
the time to confirm the Swedish company’s estimates, saying that
it had to make more analysis of its own.So far, Statoil believes Aldous Major South on its own may
hold between 400 million and 800 million boe. On Tuesday it
said the appraisal well at Aldous Major South was promising.”Discoveries are always positive, and this is a significant
oil column,” Statoil spokesman Ola Anders Skauby told Reuters,
adding that the company hoped to have a volume estimate for the
find within “a couple of weeks”.Statoil shares were trading 0.51 percent higher at 0855 GMT
on an Oslo bourse whose main index was flat.Shares in Det norske , which has a stake in
Aldous Major South, were up 8 percent while Lundin shares were
up 5.53 percent.NEW LIFE IN MATURE OIL REGIONAvaldsnes, which is connected to Aldous Major South even
though it lies in a different production licence, is estimated
to hold between 800 million and 1.8 billion boe, according to
Lundin, up from 100 million to 400 million it previously saw.By comparison, Buzzard, Britain’s largest oilfield which
feeds into the benchmark UK Forties crude oil production stream,
was found 10 years ago with reserves of around 500 million boe.The biggest new UK oilfield now in the news, which BP
has just announced it will be developing off the west of
Shetland, is the 640 million-barrel Clair Ridge oilfield.On average over the last 10 years, new oilfields discovered
in the UK sector of the North Sea have contained only around 20
million barrels.Avaldsnes/Aldous Major South could make up a fifth of
Norway’s oil supply from 2020, rising to over half by 2027,
consultancy Wood Mackenzie said earlier this month.Lundin expects production to start in 2017 while Statoil
believes it will more likely be in 2017-2018. .The Norwegian Petroleum Directorate (NPD), the agency tasked
with managing Norway’s oil and gas resources, has been more
cautious, however, suggesting it could be in 2018-2019 before
the field can produce.The NPD, like Statoil, has not confirmed Lundin’s numbers as
it carries out more analysis on the size of the find, although
it does believe that the find is undoubtedly large.It expects to book the discovery in Norway’s overall
resource estimates early next year.Norway is the world’s eighth-largest oil exporter and the
second largest for gas. Oil production peaked in 2001 and has
fallen since. In 2010 the Nordic country produced 1.8 million
barrels per day.Lundin is the operator of Avaldsnes with a 40 percent
interest. Statoil has a 40 percent interest, and Maersk Oil, a
unit of Danish shipping giant Maersk (MAERSKb.CO), has a 20
percent interest.Statoil is the operator of Aldous Major South and has a 40
percent stake. The other partners are Det norske oljeselskap
with 20 percent, Lundin with 10 percent and
Norwegian state-owned firm Petoro with 30 percent.
