Culzean 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%

Well 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.
11. 18 November, 2009
Culzean Exploration Well 11
Non 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

• 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.

• Implications of 7” Drilling Liner
• DST well kill distance from perforations.
• DST well kill volumes.
• DST multiple zone testing – mill packer or re-use.
• 5 7/8” hole – limitations on logs , smaller core- limitations on modelling
Con’s
• Slower to drill, heavier and more expensive design
• Drilling hard abrasive Palaeocene & chalks in slower 16” or 17 ½”
hole.
• Increase volume OBM cuttings for containment

35. A welcome note from the HPHT Programme Steering Committee…
Dear industry colleagues,
HPHT operations are integral to the growth of the oil and gas industry. Getting the most out of your HPHT operations requires
continuous learning and refinement of techniques and technologies to push the envelope as we continue to explore new areas,
face new challenges and capture opportunities.
The Programme Steering Committee came together in Aberdeen for extensive discussions to draw up the key topics for
the 2010 HPHT Wells Summit. We formulated an agenda with a number of new topics to cover this year including:
n Suspension and abandonment of HPHT wells
n Risk management, emergency response planning and safety of HPHT operations
n HPHT well design: From concept to well construction
n Effectively managing uncertainty in pore pressure, fracture gradient and the “transition zone”
n Delimiting the operational limits on drilling, logging & testing tools
Other major themes that have been highlighted for discussions at this year’s meeting include:
n Well architecture and delivering a safe HPHT well
n Well integrity challenges
n Emerging technologies and technology gaps for HPHT
n Operational considerations for HPHT well evaluations
The conference format is unique and mixes presentations, panel discussions, roundtables and workshops to ensure that you are
able to learn first-hand from the practical experience shared amongst both expert speakers and the wider delegate audience.
We look forward to seeing you there.

Examine critical completions Understand the need for discipline
considerations and well integrity issues integration with HPHT wells
for HPHT environments During this “hands-on” workshop, teams will work through an exercise to
carry out a plan for well construction within a set scenario. 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.
