Culzean Exploration Well Challenges
• 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%

Culzean Exploration Well
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.

18 November, 2009
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

Appraisal Well 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.

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 inAberdeen for extensive discussions to draw up the key topics for
the 2010 HPHTWells 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.

Interactive Workshops Tuesday 23rd November 2010
08.45 – 12.00 Interactive Workshop A:
Examine critical completions
considerations and well integrity issues
for HPHT environments
This in-depth workshop will give you the opportunity to assess first-hand
some of the most effective completions and well integrity challenges,and
discover the techniques and strategies required to overcome them.
During the interactive discussions,you will have the opportunity to:
n Explore in detail the use of various HPHT completion techniques
n Understand what the emerging technologies are in this space
n Examine the critical aspects of HPHT well integrity
n Address issues surrounding HPHT well integrity with application to life
of well prediction
n Gain insight into cementing practices and cement fatigue in HPHT wells
n Measure corrosive formation fluids effects on:
-Tubular integrity
- Pressure barrier sealing performance
-Well head seals
- Downhole mechanical seals in packers
n Key considerations for cement sealing and structural integrity
Workshop leader to be announced
12.30 – 15.30 Interactive Workshop B:
Understand the need for discipline
integration with HPHT wells
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
exercise,you will:
n Definethechallengesandbeingawareof“rippleon”effectsofdecisionsmade
n Determinetheplayersandtheirroles–possibleshiftinpresentorganisationrequired
n Engage in discussions as to why early buy-in from senior management
is critical
In order to maximise group participation,you will be split into teams.In your
teams,you will work out a plan based around your scenario and then you
will then report back to the whole workshop.Key considerations will include:
n Bringing the ultimate goal of production back to the initial planning stage
n Setting up a paper exercise of a well construction based on known reservoir
conditions and having back-up plans to address possible surprises
n Establishing guidelines for drilling team
In this session,you will understand why thinking about the well objectives is
critical to the well design.You will take into account the fact that if you only
look at the drilling of the well (pressure integrity of the casing) rather than
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
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.

14.30 Addressing the many challenges of HPHT well evaluations
HPHT wells offer an opportunity to shift the paradigm while adjusting the
mindset to cope with the current technological limitations.Success is often
measured through the pre-determined KPIs which can fail to encompass
the need for a fully integrated approach.In this session,you will explore how:
n Understanding past failures in reservoir management can provide the key to
future success stories
n Well planning needs to be all encompassing and deal with all aspects from
location,trajectory,well construction,drilling and completion fluid systems to
available evaluation tools
n HPHT environments not only affect the drill bit selection and downhole
steerable assemblies,but also the reservoir properties and test tools as well.
Test programmes need to apply a suite of achievable objectives and a clear
understanding of the effects of time and temperature on downhole logging
and test tools
n Good planning with sufficient lead time can make all the difference
R J Boocock,Consultant Petroleum Engineer
15.45 Group competition of the well construction process
During this group session,the delegation will be split into teams to build an
ideal well in a given scenario.
You will:
A) Consider what is currently available to you
B) Identify any current technology gaps
1) Planning tools - integrated planning,hydraulics,real time to
actual comparisons
2) Rig capacity - size,onboard mud coolers fluid capacity,MPD spread,
(And total number of“capable”rigs)
3) Drilling tools - downhole equipment premium threaded components,etc
4) Fluids - weight,rheology,variable behaviour with heating / cooling cycles,
control with mpd
5) Cement - design,testing,“foams”
6) Casing - steels etc
7) Completions - tools transferring conventional technology to ht domain
8) Well test - special tools,differing test patterns
9) Logging - real time vs.recorded vs.wireline,new developments
This group exercise is created to determine the difference between
the actual edge of the current envelope,and the theoretical limit of
upcoming potential wells.
