HPHT WELL ENGINEERING
Course Overview
HPHT (High Pressure - High Temperature) wells have a downhole environment of more than 10,000psi (690 bar) and/or 300
deg F (140 deg C). These conditions are increasingly encountered in many basins worldwide, as exploration and production
examine deeper and hotter objectives.
In attending this course, participants will gain knowledge and develops skills relating to HPHT Well Engineering. The course
focuses on key characteristics and challenges of HPHT wells from well design, planning, engineering and operational
perspectives. It covers a range of topics including:
 Well Design - Casing and drillstring design, well barriers, thermal effects, drilling fluid and cement selection
 Operational Planning - Rig selection, BOP equipment issues, rig team training
 Well Delivery – fingerprinting, well bore breathing, high-reliability drilling practices, well control and well
abandonment

 Explain why crew training and communication are critical aspects in successful HPHT well delivery

COURSE AGENDA
The following subjects will be addressed during the course
CHARACTERISTICS OF HPHT WELLS
The industry definition of an HPHT well and examines the
characteristics that make HPHT wells challenging. A review of
why HPHT wells fail is considered in order to focus attention
on the key differences between HPHT and conventional wells.
CASING DESIGN IN HPHT WELLS
A review of the principals of casing design with a focus on the
effects of temperature on casing design criteria, such as load
and yield strength changes.
The course will review uniaxial and triaxial pipe strength, the
implications of manufacturing standards and tolerances as
per ISO 10400 and the impact of downhole environmental
conditions. Participants will develop an understanding of the
how connections are tested using ISO 13679 and how to select
suitably pre-qualified connections for use in a well.
The importance of casing wear and its impact on casing design
and well integrity are discussed. Participants will master the
process of detailed casing design, identifying relevant load
conditions for the lifetime of the well and producing an
optimised casing scheme that can withstand triaxial burst and
biaxial collapse loading under downhole conditions. HPHT
Service Load design challenges such buckling and trapped
annular pressures will be addressed as well as managing the
impact of corrosion and casing wear.
DRILLING FLUIDS AND CEMENT
Temperature has a profound effect on drilling fluid rheology
while the high gradients required to balance high bottom hole
pressures create challenges to carrying capacity and barite
sag. High temperatures can also compromise drilling fluid
additives. This section addresses the selection and design of
drilling fluids for HPHT wells including the choice between
water based and oil based fluid systems. Thermal impact on
rheology and additive stability is discussed as is rig fluid
system design including shakers and mud coolers. Thermal
impact on cement slurries and cement placement practices
are also addressed.
RIG AND EQUIPMENT SELECTION
A detailed review of the essential requirements of the rig and
drilling equipment is provided which covers the rig, fluids
control equipment and well control equipment, and
instrumentation. Particular attention will be given to
qualification and testing of BOP equipment and the sizing and
performance assessment of surface gas handling equipment.
FINGERPRINTING
The impact of temperature in fluid density and volume
downhole means that conventional well control signals are
less reliable in HPHT operations. It is critical to understand the
normal behaviour of a well such that abnormal behaviour can
be rapidly identified and reacted to. Proactive information
gathering or “fingerprinting” prior to and while drilling an
HPHT section achieves this. The array of data to be analysed
and modern mud logging techniques that can be used are
addressed.
WELL CONTROL
Comprehensive knowledge and sound skills in the principals
and practisers of well control are critical to HPHT operations.
This section addresses pore pressure prediction and narrow
margin environments and their profound impact on kick
tolerance in the region of the transition zone. The origin of
abnormal pressure, and an explanation for narrow pressure
margins between pore and fracture pressure is covered. The
causes of kicks and kick detection are addressed including
early kick detection technology. Well control procedures to
combat influxes taken with the drillstring on bottom, off
bottom and with the drillstring out of the hole are reviewed.
These will include driller’s method, volumetric method,
bullheading, combined volumetric and stripping method and
snubbing.
KICKS AND LOSSES
Given the narrow margin between formation pressure and
fracture pressure in HPHT wells, the situation may arise where
there are simultaneous influx and losses leading to
underground flows. The causes and treatments for
underground flows are described and explained.
TEAMWORK AND TRAINING
Competence, teamwork and communications between well
delivery team members is critical to ensure the safe drilling
of HPHT wells. This section examines how rig team
communication and performance on critical wells can be
enhanced by processes such as “Drilling the Well on a
Simulator”.
HPHT WELL TESTING
This section addresses the surface and downhole equipment
required to temporarily complete and test flow HPHT wells.
Operating practises to address the challenges of HHPT well
testing are discussed.

What past participants said about this training programme:
 “Good and useful course for Drilling engineer who involves in designing and operations” Senior Drilling Engineer,
Talisman Malaysia
 “Good and handy insight to HPHT Well Engineering” Drilling Consultant, Halliburton Energy Services
 “This was a good introduction to some complexity of HPHT Wells and made me realise the time effort it take to plan
these wells” Drilling Engineer, Oil Search
 “Good general overview of the things to consider in the early stages of HPHT well planning” Drilling Superintendent,
Talisman Malaysia
HPHT DRILLING PRACTISES
High reliability well delivery requires the implementation of
drilling practises that can mitigate problems associated with
high mud gradients/mud rheology, narrow margin
environments and thermal effects. Such practises must
address pressure limitations of conventional mud circulation
systems such that the well can be safely closed in with high
surface pressures at any time. This section addresses HPHT
processes and practises and introduces the concept of the
“Safe Drilling Checklist”.
MANAGED PRESSURE DRILLING (MPD)
MPD offers solutions to a number of the challenges of HPHT
well delivery, specifically the narrow margin between pore
and fracture pressure through the transition zone. Some
Operators require all “dry BOP” HPHT wells to be drilled with
MDP in place while recent riser developments are seeing
subsea and deepwater HPHT wells using MPD equipment too.
This section addresses the benefits of MPD operations and
examines the equipment and practises for its implementation
in HPHT wells.
BOTTOM HOLE PRESSURE MANAGEMENT
The effect of temperature and pressure on drilling fluid
density, the importance of ECD management, and use of PWD
is explained. The importance of operational procedures to
minimise surge and swab effects is emphasised. Kick
tolerance and gas behaviour is discussed in terms of the
effects of temperature and the importance of monitoring gas
while drilling is explained. Ballooning, breathing and
supercharging will be explained.
HPHT WELL EVALUATION
This section reviews the temperature and pressure limitations
of conventional logging tools and examines the equipment
and operating practises now available to evaluate wells in
hostile conditions. Evolving technologies including ahead of
the bit measurements and the use of real time petrophysical
data to update pore pressure prediction models and optimise
drilling fluid gradients will be discussed.
HPHT WELL INTEGRITY AND FAILURE MODES
This section will address well integrity problems associated
with HPHT Well Delivery and Production. A number of case
studies will address problems encountered during the drilling
phase, reservoir compaction during production as well as
zonal isolation prior to and after well suspension and
abandonment.
