The Top Shetland situation – incr. pressure
Opeqa
tions
• The Shetland group was
mapped in detail during
2010
• The pressure is presumed
to spread in fractures and
faults from the reservoir and
in the chalk at the top of the
Shetland group
6 -
Well integrity status
Opeqa
tions
• Shut in wells
− 20 shut in wells due to suspicion of integrity problems
− 29 producers to maintain pressure balance in reservoir
− 1 additional water injector is shut in due to top side limitations
• The Hordaland group functions as a barrier in a well integrity context
• No leakage has been detected from the reservoir, either to the seabed or to the shallow
layers as a result of Statoil’s operations at Gullfaks
• New adjusted water injection strategy implemented
• No safety issues at Gullfaks
• Maintaining a good dialog between management and employees
7 -
Hordaland as a barrier
Opeqa
tions
• The Hordaland group on Gullfaks contains large volumes of sand
• The Hordaland group's sand complex covers the entire Gullfaks licence
• Volumes used in calculations very conservative – still expect a pressure increase of only 2
bar
• The Hordaland group can withstand 25-45 bar of pressure build-up before they fracture
further
• The Hordaland group functions as a barrier in a well integrity context, because it will
prevent migration of pressurised fluids to the seabed

Robust and profitable projects
Opeqa
tions
• Drilling Facility Upgrade (GFA, GFB and GFC)
− Upgrade of drilling facilities to prolong lifetime to year 2030
• Pre Compression (GFC)
− Increase pressure from GF South (L and M frame) to increase oil recovery
• Snorre to Gullfaks A
− Replace Statfjord A as oil / gas processor for Snorre A, including storrage and loading of oil
• Gullfaks Omega
− New subsea templates or wellhead platform to increase oil and gas recovery

Forward looking statements
This presentation contains certain forward-looking statements that involve risks and uncertainties.
In some cases, we use words such as "ambition", "believe", "continue", "could", "estimate", "expect",
"intend", "likely", "may", "objective", "outlook", "plan", "propose", "should", "will" and similar expressions
to identify forward-looking statements.
All statements other than statements of historical fact, including, among others, statements such as
those regarding: expected equity production; regularity, efficiency and productivity goals for future
operations and projects; our financial position, results of operations and cash flows; expected dividend;
our future market position; business strategy; expected changes in ownership interests and structures;
expected project development expenditures; plans for future development (including redevelopment) and
operation of projects; reserve information; reserve recovery factors; future reserve replacement ratio;
entitlement volumes; expected timing of resumption of certain exploration drilling in the US Gulf of Mexico;
future ability to utilise and develop our expertise; future growth (including future production growth); our
future ability to create value; oil and gas production forecasts; future composition and maturity of our
exploration and project portfolios; exploration expenditure; expected exploration and development
activities and plans; planned turnarounds and other maintenance; expected unit production cost; expected
refining margins; expected gap between entitlement and equity volumes; expected impact of contractual
arrangements on equity volumes; expected production and capacity of projects; projected impact of laws
and regulations (including taxation laws); the impact of the uncertain world economy; expected capital
expenditures; our expected ability to obtain short term and long term financing; our ability to manage our
risk exposure; the projected levels of risk exposure with respect to financial counterparties; our ability to
obtain financing at attractive funding cost levels; the expected impact of currency and interest rate
fluctuations (including USD/NOK exchange rate fluctuations) on our financial position; oil, gas and
alternative fuel price levels and volatility; oil, gas and alternative fuel supply and demand; the markets for
oil, gas and alternative fuel; projected operating costs; the completion of acquisitions, disposals and other
contractual arrangements; estimated values in use; estimated cash flows; estimated costs (including costs
for plugging and abandonment of wells); estimated future operational leasing commitments; future number
of vessels employed; estimated decline of mature fields; future market conditions; future utilisation of
capacity contracts; our HSE objective; impact of PSA effects; and the obtaining of regulatory and
contractual approvals, are forward-looking statements. You should not place undue reliance on these
forward-looking statements. Our actual results could differ materially from those anticipated in the
forward-looking statements for many reasons, including the risks described above in "Risk update".
These forward-looking statements reflect current views with respect to future events and are, by their
nature, subject to significant risks and uncertainties because they relate to events and depend on
circumstances that will occur in the future. There are a number of factors that could cause actual
results and developments to differ materially from those expressed or implied by these forward-looking
statements, including levels of industry product supply, demand and pricing; currency exchange rates;
interest rates; trading activities; the political and economic policies of Norway and other oil-producing
countries; general economic conditions; political stability and economic growth in relevant areas of the
world; global political events and actions, including war, terrorism and sanctions; changes in laws and
governmental regulations; the lack of necessary transportation infrastructure when a field is in a remote
location; the timing of bringing new fields on stream; material differences from reserves estimates; an
inability to find and develop reserves; adverse changes in tax regimes; the development and use of new
technology; geological or technical difficulties; operational problems; security breaches; the actions of
competitors; our ability to successfully exploit growth opportunities; the actions of field partners; industrial
actions by workers; failing to attract and retain senior management and skilled personnel; failing to meet
our ethical and social standards; operational catastrophes; security breaches; natural disasters and
adverse weather conditions and other changes to business conditions; and other factors discussed
elsewhere in this report. Additional information, including information on factors that may affect Statoil's
business, is contained in Statoil's 2009 Annual Report on Form 20-F filed with the U.S. Securities and
Exchange Commission, which can be found on Statoil's website at www.statoil.com.
Although we believe that the expectations reflected in the forward-looking statements are reasonable,
we cannot assure you that our future results, level of activity, performance or achievements will meet
these expectations. Moreover, neither we nor any other person assumes responsibility for the accuracy
and completeness of the forward-looking statements. Unless we are required by law to update these
statements, we will not necessarily update any of these statements after the date of this review, either
to make them conform to actual results or changes in our expectations.
