Forward Looking Statements This presentation contains certain forward-looking statements that involve risks and uncertainties. In some cases, we use words such as "believe", "intend", "expect", "anticipate", "plan", "target" and similar expressions to identify forward-looking statements. All statements other than statements of historical fact, including, among others, statements such as those regarding: plans for future development and operation of projects; reserve information; expected exploration and development activities and plans; expected start-up dates for projects and expected production and capacity of projects; the expected impact of USD/NOK exchange rate fluctuations on our financial position; oil, gas and alternative fuel price levels; oil, gas and alternative fuel supply and demand; the completion of acquisitions; and the obtaining of regulatory and contractual approvals are forward-looking statements. 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; price and availability of alternative fuels; currency exchange rates; 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; the timing of bringing new fields on stream; material differences from reserves estimates; inability to find and develop reserves; adverse changes in tax regimes; development and use of new technology; geological or technical difficulties; the actions of competitors; the actions of field partners; the actions of governments; relevant governmental approvals; industrial actions by workers; prolonged adverse weather conditions; natural disasters and other changes to business conditions. Additional information, including information on factors which may affect Statoil's business, is contained in Statoil's 2010 Annual Report on Form 20-F filed with the US Securities and Exchange Commission, which can be found on Statoil's web site 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 this Capital Markets Day, either to make them conform to actual results or changes in our expectations. 2 -

Reservoir Contact in Tight Rock is Critical • Propped fractures touch more rock than multi-lateral wells • It is more effective to touch rock with a fracture than with a drill bit • Simple, single laterals designed for stimulation • With 150 fracs, estimate ~6,000,000 ft2 of contact 5 laterals drilled from one wellhead Propped fractures *Overhead, map view h = 50 ft L = 200 ft Half-length f Tiny frac, perhaps 20,000 lbs of proppant at 1 lb/sq ft 2 wings * 2 faces * 200 ft * 50 ft = 40,000 ft² of reservoir contact Multi-lateral: 15,000 ft of drilled length in 5 laterals = <24,000 ft² of reservoir contact 11 -
