7324/8-1 Wisting Central Well Summary- Discovery Well – Sept 2013 Wisting Central Well Objectives: Test Jurassic prospectivity (Stø Formation) Well Results: Very shallow reservoir – only 250 below seabed Upper part homogeneous with good properties, Lower part heterogeneous; but still sand rich Well with 50-60m oil column; Central segment 60-160 mmbo recoverable oil Extensive data acquisition and sampling , no DST AI Secondary Target: Snadd Formation, tight, shows only 8 | OMV (Norge) AS, March 11, 2015

Reservoir Challenges Wisting has some unique conditions Shallow reservoir 250m below seabed Reservoir conditions Low Pressure 70 bars Low Temperature 16 ° C No comparable case studies Other Realgrunnen prospects/leads on Hoop High will – if successful - face equivalent challenges 10 | OMV (Norge) AS, March 11, 2015
Reservoir – how much can we get out? Drive Mechanisms How strong is aquifer ? 20 Current reference studies includes: Water injection as drive mechanism Horizontal production wells 80 Subsea multi-phase pumps Recovery Factor A big uncertainty Ranges from low 20’s to 50+ % 55 45 ? Contribution from heterogeneous part Major influence on economics 11 | OMV (Norge) AS, March 11, 2015
Horizontal Wells: None drilled offshore at this depth Well Design and Planning Well design limited by kill simulation results Cap rock integrity & barrier placement BHA design (high dog legs, limited weight on bit, high surface RPM) Uncertainties in building behavior Hole cleaning in low pressure /high permeable sandstone reservoir Challenging completion design Horizontals would be essential for development concept - less wells and higher recovery Prove feasibility of horizontal wells for Concept Selection 12 | OMV (Norge) AS, March 11, 2015
Facility Challenges – Sub-Sea Subsea Wells distributed over a large area Not much pressure to “play with” Pressure boosting required to keep flow rates high and back pressure on wells low. Trade-off between CAPEX (pre-installed equipment and piping) and production rates Work in progress: All boosting mechanisms (sub-sea and down-hole) Experience transfer (partners, leading vendors ) for “sub -sea factory” equipment 13 | OMV (Norge) AS, March 11, 2015
Facility Challenges – Flow Assurance Hydrates: Early field life - Low temperatures, low pressures. Outside hydrate zone. Late field life - higher water cut, higher density - pressurizes fluid into the hydrate zone. Wax: Studies ongoing to determine impact Round trip pigging - adds to sub-sea CAPEX Solutions under review: Hot oil circulation, direct electrical heating, chemicals 14 | OMV (Norge) AS, March 11, 2015
Facilities Challenge - Power supply HOOP High is far off existing Infrastructure - not like in North Sea – Stand alone solution needed Potential oil development at Wisting, but limited associated gas GOR 37-50 Sm3/Sm3 Need to maintain oil rate for sufficient gas to power generation No opportunities to buy/import from a near-by gas export line Too far for Power from Shore Solutions under review: Re-inject excess gas in early life, produce back in late life (needs sub-surface studies) or dual fuel solutions 15 | OMV (Norge) AS, March 11, 2015
Facility Challenge: Installation Design Floater concept – 400 water depth, What type of floater Ship, Spar, Buoy-shaped? How big – capacity, storage needs Wisting only Hub concept for area Overall design concept Winterization low maintenace new standards? Export – shuttle tanker (Veidnes) or pipeline 16 | OMV (Norge) AS, March 11, 2015
Location Challenge - HSSE Remote location Northernmost discovery ever in Norway (310 km from Hammerfest) Low density of resources in the area Medevac to Tromsø, up to 4 hours or more Telemedicine solution plus two nurses on board Long periods of dense fog expected Evacuation solution independent of Helicopters Stand by vessel with capability to operate in harsh weather is the primary resourse 17 | OMV (Norge) AS, March 11, 2015
Location Challenge – Weather & Environment Long-term observations & detailed data for Hoop Area are sparse PL537: Metocean buoy installed at Wisting Collaborating with other Barents Sea operators and relevant Authorities to expand knowledge of Barents Sea operating conditions Polar lows, fog in summer, prevailing wind directions etc. Barents Sea in general more “friendly” met-ocean conditions than Norskehavet Collaboration to better understand the marginal ice zone eco-system 18 | OMV (Norge) AS, March 11, 2015
Location Challenge – Oil Spill Extensive simulations of diverse spill scenarios based on actual oil and reservoir properties Strict oil spill recovery requirements Spill detection within one hour SECurus detection system (radar plus IR) NOFO vessel at location Full barrier I and II in place within 24 hrs DST was seen by satellite... Formal collaboration agreement with main Barents sea operators on a wide range of arctic HSSE issues in place now. Barents Sea Exploration Collaboration (“ BaSEC ”) established on March 9, 2015 19 | OMV (Norge) AS, March 11, 2015
Location Challenge – Where is the Ice? HOOP HIGH HOOP HIGH Average sea ice concentration map for December Average sea ice concentration map for January 20 | OMV (Norge) AS, March 11, 2015

Hoop High Challenges – Conclusions Resources: Wisting – has proven up material subsurface potential – a shallow and unique reservoir in Jurassic Realgrunnen Other plays – Snadd & Kobbe (Triassic) – attempted but not successfull to date Development challenges Primarily driven by resource volumes & shallow reservoir Secondarily by limited infrastructure and logistics for location Commercial challenges (oil price ..) need to be resolved Way Forward Confirmation of additional potential in the future (23 rd Round fwd.) will provide for development of hubs & regional infrastructure OMV committed to mature Wisting and establish a PDO in 2019 22 | OMV (Norge) AS, March 11, 2015
