18 November, 2009Culzean Exploration Well Challenges 8 • Limited offset wells – 22/25a-1 well drilled in 1986 by BP. Littered by drilling problems, failed to reach TD. Extensive well control issues , including classic wellbore breathing. Limited detailed information on this well. • High geological uncertainty. • High Pressure Uncertainty - BHP Range 17.0 ppg to 18.5 ppg emw • ~380 deg F BHT. • Drill close to crest - Narrow window between PP & FG - potentially un-drillable! OVERALL CHANCE OF DRILLING SUCCESS =53% Breakdown of 47% Drilling Risk of Failure: Risks 1 to 3 – Potentially too narrow and un-drillable drilling window 1. Aquifer Overpressure Greater than Predicted = 20% 2. Sand above the target reservoir =2.5% 3. Fracture Gradient Less than Estimated =25% 4. Problematic Gas in Hidra =10%

18 November, 2009Culzean Exploration Well 10Well Objectives• Drill a safe and incident free well.• Reach well planned TD.• Penetrate all reservoir prospects.• Successfully log all reservoir prospects.• In success case, MDT pressures and samples over reservoir prospects.• No Coring• No DST to be carried out.• P&A.
18 November, 2009Culzean Exploration Well 11Non DST/Finder Well Exploration Rational• Chances of Exploration Success?• Extra cost to include DST considerations in casing design. • Final hole size drives well design. • HPHT DST standard tools – 5” OD • Test tools as close to perforations as possible ( well kill volumes & complexity if testing with a drilling liner) • Thus preferred 8 ½” hole x 7” liner at TD for DST well. • Heavier casing design required – HPHT Heavy vs HPHT Light • Increased loads – Increase casing specification – Increased costs (10 ¾” - 9 7/8” up to £1.0m more, 13 5/8” or 14” vs. 13 3/8”) • DST Long Leads ~£1m • Contingency tie-back string ~ £1m.• DST planning – manpower and hours• Total Cost Differential ~ £8m- £10m less for Non/DST Finder “Light” design

Appraisal Well Design 18 November, 2009 25 • Exploration Well HPHT ”Light” Design & 12 ¼” TD • Achieved ”All” well objectives, still had one more contingency hole size available. • However, went too deep into PTZ w/ shallow 13 3/8” shoe. • Weak zone(s) in Paleocene (Forties) and/or top Tor. • Design incompatible w/ drive 9 7/8” shoe as deep as possible into PTZ. • Exploration Well - Needed Contingency Liner Option to Negotiate PTZ. • Appraisal well - DST Required from multiple zones • Conclusion: HPHT ”Heavy” Design required with deep set 13 5/8” Casing. • Optimum setting depth for 9 7/8” shoe? As deep as possible, preferably the Valhall. • 13 5/8” shoe depth? To facilitate above.

Through this in-depth workshop will give you the opportunity to assess first-hand This exercise, you will: some of the most effective completions and well integrity challenges, and discover the techniques and strategies required to overcome them. n Define the challenges and being aware of “ripple on” effects of decisions made n Determine the players and their roles – possible shift in present organisation required During the interactive discussions, you will have the opportunity to: n Engage in discussions as to why early buy-in from senior management n Explore in detail the use of various HPHT completion techniques is critical n Understand what the emerging technologies are in this space order to maximise group participation, you will be split into teams. In your In n Examine the critical aspects of HPHT well integrity teams, you will work out a plan based around your scenario and then you n Address issues surrounding HPHT well integrity with application to life will then report back to the whole workshop. Key considerations will include: of well prediction n Bringing the ultimate goal of production back to the initial planning stage n Gain insight into cementing practices and cement fatigue in HPHT wells n Setting up a paper exercise of a well construction based on known reservoir n Measure corrosive formation fluids effects on: conditions and having back-up plans to address possible surprises - Tubular integrity n Establishing guidelines for drilling team - Pressure barrier sealing performance this session, you will understand why thinking about the well objectives is In - Well head seals critical to the well design. You will take into account the fact that if you only - Downhole mechanical seals in packers look at the drilling of the well (pressure integrity of the casing) rather than n Key considerations for cement sealing and structural integrity size, type and depth of the specific string, you may plan yourself into a corner with no room to adjust should higher pressures be encountered Workshop leader to be announced further up-hole. This could mean that you need to run another intermediate string and that could not be available or be wrongly sized to enable test tools to get to the depth required. You need to avoid having a drilled hole that nothing can fit in for evaluation purposes. Jointly a final plan is made complete with contingencies and objectives all agreed. Led by R.J.
