Content Introduction - OMV in Norway Wisting Discovery General Challenges Reservoir Challenges Drilling in Shallow Reservoir Facilities Requirements Location and weather Stakeholders Summary 9 | 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

Non-Technical Challenges  Local Communities & Stakeholders  Fishing & Tourism  NGO’s & Climate Change Discussion  Image taken from Transocean Barents, May 31, 2014 21 | 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
