DAY 1 Overview
Prior to Drilling & Prior to Spudding the Well
Welcome Introduction & Course Overview
Industry Definitions of Deepwater & Ultra Deepwater
The Commonest Reasons Why Deepwater Wells Over-run in
Terms of Cost / Why They Fail to Meet Their Objectives
The Deepwater Environment
 An introduction to the deeper water environment (i.e.
deeper than standard semi-submersible rig water depth
limitations) – what the key environmental considerations
are, such as currents (current profiles from the sea-bed to
surface will be discussed), waves, and combined current /
wind / wave force loadings.
Environmental Effects on Marine Vessels
 How the environmental loadings referenced above affect /
impact marine vessels, such as vessel movement in the
lateral plane, vertical plane and intermediate planes –
pitch, yaw and heave. The effects of these forces and
movements upon vessel stability.
Drilling Vessels For Deepwater: Rig/Drill-ship Selection
An Introduction to Semi-Submersible Rigs & Drill Ships &
Their Usage
 Capabilities of deepwater semi-submersible rigs.
Capabilities of deepwater drillships. The key attributes –
and differences – in their designs and capabilities. When
semi-submersibles are typically used and when drill ships
are typically used.
Semi-submersible Rig Stability & Station Keeping
 The effects of current / wind / wave force loadings and
shallow gas eruptions upon rig stability :- metacentric
height, centre of gravity and survivability.
Drill Ship Stability & Station Keeping
 An introduction to drill ship vessel design – how the
different generations and classes of drill ships have been
designed to cope with environmental loadings and water
depth. A look at the different designs / classes of drill ship
available, their design and functional characteristics, their
capabilities and limitations. The effects of current / wind /
wave force loadings and shallow gas eruptions upon drill
ship stability :- metacentric height, centre of gravity and
survivability.
Sea-bed Surveys Prior to Spudding the Well
 The use of vessels using sonar / side-scan sonar to
acquire sea-bed data. The use of ROV’s and video
cameras to survey the sea-bed. Grab samples. Core
samples.
Shallow Gas Surveys Prior to Spudding the Well
 The way in which shallow gas seismic data is acquired,
what to look for and what the risks are.
Other Typical Deepwater Formation Issues
 Methane gas seeps, mud volcanoes and weak formations.
The Problems Associated with Weak Formations
 Why weak formations are such a problematic issue on
deepwater wells – the effect on casing shoe strength and
kick tolerance
DAY 2 Drilling Unit 1
Spudding the Well: Top Hole & Running the Conductor
Videos will show how casing strings are landed and how
the pack-offs are activated.
Method 1—Drilling
 This section of the course looks at drilling the top-hole
section to TD as opposed to washing and covers the
benefits and disadvantages of such methodology. The
problems of encountering weak formations are discussed
and potential solutions are covered. Types of services
performed on slickline and their problems causing a
fishing job
Method 2—Washing the Top Hole Section
 This section of the course looks at washing the conductor
to section TD – the advantages and disadvantages –
specifically where sea-bed formations are weak and
drilling and cementing the conductor is not effective.
Drilling Surface Hole
 The course now looks at the cases of exploration,
appraisal and development wells with regard to drilling
surface hole below the conductor. The case of drilling
below the washed conductor is covered as is the case of
drilling below the drilled and cemented conductor. The
risk of shallow gas is covered and what a semi-
submersible rig or drill ship should do if shallow gas is
encountered. The surface casing string setting depth :
The impact of typically weak formation upon casing shoe
strength and kick tolerance.
Running the Surface Casing String
 In all cases typically the surface casing string is cemented
back to surface. Cement returns are seen at the sea-bed
through exit ports in the wellhead assembly by the ROV.
Once cemented in place (usually deeper than any shallow
gas section) the 18¾” High Pressure Housing is exposed.
The purposes of this housing are discussed for
exploration, appraisal and development wells.
Subsea Drilling Equipment
 The following key items of subsea drilling equipment are
covered in relative detail, such that functionality, design
and service are covered – and understood – by the
delegates.
Subsea Wellheads
 Design and functionality, casing hangers, pack-off
systems, set-down and rotation. The 30” Housing; the
18¾” High Pressure Housing (which connects to the H4
Connector); Subsequent casing string housing; sealing
assemblies.

Spudding the Well: Top Hole & Running the Conductor
Temporary and Permanent Guidebases
 Their design, functionality and operation.
Subsea Templates
 Their design, functionality and operation.
Subsea BOP Stack
 This is, necessarily, a very detailed section, since subsea
BOPE varies considerably from surface BOP stacks. Their
design and functionality is covered – the 4 rams and 2
annular preventers – subsea hydraulics – and all ancillary
equipment. When and how the BOP stack is run; how it
lands and latches onto the 18¾” High Pressure Housing
with the H4 Connector; how it is tested; use of overpull.
The use of the “blue” and the “yellow” pod system.
Hydraulic signals. MUX signals. Annular Preventers;
Rams; Redundancy; Use of Acoustics / Deadman
Emergency System.
The H4 Connector
 Their design, functionality and operation will be covered.
LMRP – Lower Marine Riser Package
Why a 10 Degree limitation is required. Ball-joints and
Flex-joints will be discussed.
The Riser System
Essential riser maintenance. The two systems of joining
riser joints together. Automated riser handling systems.
Choke and Kill lines. The problems of long risers – fatigue,
cleaning-out drilled cuttings (use of riser boost pumps),
buoyancy, mud cooling etc.
Telescopic Joints / Slip Joints
 Their design, functionality and operation will be covered
with particular respect to how the system compensates
for rig heave.
Riser Tensioner
 The design, functionality and operation will be covered
with particular respect to how the system applies tension
to the riser.
Heave Compensator
 The design, functionality and operation will be covered
with particular respect to how the system compensates
for rig heave. System charge pressure will also be
discussed and video will be used to explain the principles.
DAY 3 Drilling Unit 2
Drilling Below the Surface Casing String
Subsea Bop Stack Installed
 Now that we have covered key subsea equipment and its
landing and utilisation after drilling top hole and surface
hole, we will look at drilling the subsequent (i.e. deeper)
hole sections – 17½” / 16”, 12¼”, 8½” / 6” hole sections
and study the problems associated with drilling these
sections. This will be done in overview format, since the
delegates will already be experienced in drilling (though
perhaps in other areas).
 One of the key areas in any drilling operation is, of course,
well control. Surface stack personnel may not be aware
of choke and kill line considerations, and how the choke
line friction factor significantly affects what we see on the
SICP Casing Pressure Gauge. This will be addressed in the
next section, as will all items of equipment – design,
functionality, operability and capability .
 This section of the course looks at washing the conductor
to section TD – the advantages and disadvantages –
specifically where sea-bed formations are weak and
drilling and cementing the conductor is not effective.
Key Drilling Issues – Potential Problems and Solutions
 There are, potentially, many problems associated with
deepwater drilling and the following areas / topics are
discussed in appropriate detail.
The Problems Associated With Drilling Weak Formations –
And Potential Solutions
 The problems associated with weak / unconsolidated
formations e.g. wellbore collapse, hole cleaning, poor
casing shoe strength and kick tolerance etc. Potential
solutions e.g. rock mechanics to determine minimum mud
weight requirement; drilling fluids and chemistry /
inhibition; minimum flow rates to determine optimal hole
cleaning; the use of PWD to determine ECD; casing shoe
setting depth; FIT as opposed to LOT; squeeze cementing;
the use of expendables.
The Problems Associated With Drilling Deep Wells – And
Potential Solutions
 Cuttings transportation and the necessity of a riser boost
pump; the effects of temperature changes upon the mud
system; parasitic pressure losses; hydraulics; how to
optimise drilling fluids selection; bit selection and
economics; casing and cementation. Casing Setting
Depths. Hydrates.

subsea drilling programme will be cross-referenced to
maximise learning.
Emergency Operations whilst Drilling
 Emergency disconnect: - Riser hang-off due to storm
collision. Weather limit to disconnect and hang-off with
LMRP. Hang-off limit exceeded – stay latched or
disconnect? Hard versus soft riser hang-off methods.

 Combined wind / wave / storm force loading effects.
Excessive hydrate formation. Bullheading instead of
killing the well through Drillers or Wait & Weight Method.
Shallow gas blowout. Explosion. Fire. Drifting in storm.
Emergency Evacuation. Emergency Event Management.
DAY 4—Practical Workshop
Deepwater Well Design Teamwork Exercise
 During this final day of the course, delegates will work as
teams to design, in outline, their own deepwater well and
derive an outline drilling programme re their designed
well so that the key objectives of maximum safety,
maximum efficiency, maximum oil production and
maximum profitability are attained.
 It is expected that all of the course material will be
utilised during the exercise and that the findings from the
recent deepwater well failure and deepwater well success
will be utilised.
 A “key points overview” presentation will be given by the
teams toward the end of the course to show that course
learnings have been fully understood and assimilated.
DAY 4—Practical Workshop
Examination/Review of Recent Deepwater Drilling Cases
(Failures and Successes Case)
 This section of the course looks at recent failures and
successes regarding both ends of the spectrum re
deepwater drilling.
 The first examination invites delegates to review the likely
causes of a recent deepwater well failure which resulted
in a catastrophe and the second examination invites
delegates to review a recent deepwater well which was
successful and to compare the differences and results
between the two wells.
 This is a teamwork exercise and the findings / results will
“feed into” the final day of the course – a teamwork
exercise where delegates are invited to partake in their
own teamwork deepwater well design.
