WELL INTEGRITY TRAINING
1 Introduction
The Well Integrity Forum (WIF) was established in 2007 and one of the main issues that was
initially brought up for review was well-integrity training. WIF members acknowledge a need for
well-integrity training of key personnel working with well integrity offshore and onshore. This
was also one of the key findings in an earlier PSA well-integrity survey.
A survey of operators’ well-integrity-training practices, experiences, opinions and ideas was
carried out and used as a basis for developing a well-integrity-training guideline. This chapter
describes WIF members’ recommendations for well-integrity training and is intended to function
as a guideline to the oil industry.

3 Background
A survey was completed by WIF members and this formed the basis for discussion and
development of the guidance in section 4. The feedback focused on learning, present practice,
opinions and ideas.
The survey included the following questions:
• Main objective for a well integrity course?
• What should be covered in the well integrity training?
• Should the course include any exercises?
• Timing and schedule, how many days and if applicable, when?
4. OLF Recommended Guidelines for Well Integrity

___________________________________________________________________________
• Who to participate and mixture of skills in one group?
• Handouts and/or documentation?
• Computer based vs. class room based – or other methods?
• Training a part of competency management system?
4 Training Guidelines
What to cover in a well integrity course and timing of training
The recommended training is listed below in a preferred sequence and with estimated number of
training days for each element. Note that this recommendation applies to all personnel with
assigned responsibilities for well maintenance, operations, servicing, design and construction.
1. Well Integrity Fundamentals (see Appendix A) – Typically 1 to 2 days
2. Norsok D-010 terminology and principles – Typically 1 day
3. Company specific training (test procedures, well design and internal requirements) –
Typically 1day
Who should participate?
Personnel directly responsible and or involved in Well Integrity should have the recommended
training. Examples of who may be required to have this training are as follows:
1. Production operation personnel offshore (including OIM, production supervisors, control
room operators, technicians and senior technicians);
2. Production operation personnel onshore (incl. Ops sup, production engineers, production
technologies, HSE personnel);
3. Drilling/completion/intervention engineers (including drilling supervisor and drilling
superintendent);
4. Rig contractors like drillers and tool pushers; and,
5. Service-company engineers and operators with delegated responsibilities in well integrity.
Each company should evaluate on ‘as per needs’ basis who in their workforce is required to attend
the recommended training.
It is recommended that management responsible for Well Integrity should be trained.

___________________________________________________________________________
Type of training – Class room based versus computer based
Class room training is preferred for company specific training. Both class room based and
computer based training is good for training in Norsok D-010 and well integrity fundamentals.
Particularly for the computer based training method, it is recommended that the training include
exercises, case solving and questions and be completed with a test. Additionally for class room
training it is recommended to include group work exercises.

Chapter 2
WELL HANDOVER DOCUMENTATION
1 Introduction
The Well Integrity Forum (WIF) was established in 2007 and one of the main issues that was
initially identified for its review was well handover documentation. NORSOK D-010 has one
section (section 8.7.1) where the content of a well handover documentation package is outlined.
Availability of, knowledge about and content of the well handover document were also main
elements that were highlighted by the PSA in their well integrity survey as an area for
improvement.
This chapter describes WIF members’ recommendations for well handover documentation and is
intended to function only as a guideline for the Norwegian oil and gas industry.
2 Background
A survey completed by WIF members formed the basis for discussion and development of the
guidance given in section 3. The body content of the handover documentation varied very little
amongst the members, but the information was located and organized in different places.
3 Discussion
The survey showed that the majority of information already included in the company specific well
handover documents was common amongst the companies. All companies also had exceeded the
NORSOK standard by including well barrier schematics. In the sections below the recommended
guidelines for minimum content per focal area are listed. The format for how the documentation is
structured has not been looked at, and is left to the discretion of each operator to organize the
information.

___________________________________________________________________________
a. Well Construction Data
The handover should contain the following well construction information:
• Wellhead data with schematic
• Xmas tree data with schematic
• Casing program (depths, sizes)
• Casing and tubing data, including test pressures
• Cement data
• Fluid status, tubing and all annuli
• Wellhead pressure tests
• Tree pressure tests
• Completion component tests
• Perforating details
• Equipment details such as identification or serial numbers
b. Well Diagrams
The handover documentation should include the following two well schematics:
• Well barrier schematic with well barrier elements listed

C. Handover Certificate
The handover documentation should also include a handover certificate. The certificate should
include actual status at handover on the following:
• Valve status
• Pressure status
• Fluid status
d. Operating Input
Operating limitations for the well should also be included in the well handover documentation
package. As a minimum the following information should be included:

Chapter 3
WELL BARRIER SCHEMATICS FOR THE
OPERATIONAL PHASE
1 Introduction
One of the Petroleum Safety Authority's (PSA) findings from the spring-2006 well-integrity
audit was the requirement for the creation of well barrier schematics (WBS) for the
operational-phase of each individual well on the Norwegian Continental Shelf (NCS). Each
operating-company worked to fulfill this requirement, independently of other operators. As a
whole the industry used the WBS's presented and well-barrier elements (WBE) defined in the
NORSOK D-010 standard as a basis in developing their own WBS format. At the industry-
organized, well-integrity workshop held in March 2007, the need for common, minimum
guidelines for the subject WBS's was identified to help standardize this tool within the
industry. The same workshop resulted in calls for establishing a well-integrity forum (WIF)
to promote open and frequent discussion of well-integrity related issues amongst the NCS
operators. One of the WIF's tasks was to further investigate the use of WBS amongst the
operating companies and propose a minimum level of detail which should be included in each
well specific WBS.
This document summarizes the WIF's guideline of minimum data to be presented on WBS's
of all NCS wells in the operational phase. These guidelines may re-state and/or add to
existing requirements specified in the governmental regulations and NORSOK D-010
standard. The attached example WBS has been included for the purpose of illustrating the
recommended guidelines
2 Background
The task to establish a common WBS has been discussed and refined in WIF. The agreed
guidelines of minimum data are listed below.
11. OLF Recommended Guidelines for Well Integrity
No.:117 Date effective: 01.10.08 Rev. no: 1 Rev. date: 10.12.08 Page: 11
___________________________________________________________________________
3 Guidelines of minimum data
The following minimum data have been agreed upon and act as a guideline:
1. The formation strength should be indicated for formation within the barrier envelopes.
2. Reservoir(s) should be shown on the drawing.
3. Each barrier element in both barrier envelopes should be presented in a table along
with its initial integrity-verification test results.
4. Depths should be shown relatively correct according to each barrier element on the
drawing.
5. All casing and cement, including the surface casing, should be on the drawing and
labelled with its size.
6. There should be separate fields for the following well information: Installation, well
name, well type, well status, rev. no and date, “Prepared by”, “Verified/Approved by”.
7. Include a Note field for important well integrity information.
4 Discussion on minimum data
4.1 The formation strength should be indicated for formation within the
barrier envelopes
In all well designs, formation will be within the barrier envelopes and may therefore be
exposed to reservoir and well pressures. It is important that it is understood which formations
are inside the barrier envelopes and ensured that they are not exposed to pressures exceeding
their strength. Exceeding the formation strength may result in leaks on the outside of casings
and cement, outside the barrier envelopes. This is important for all well types; however,
special attention should be given to injector wells.
The strength of the formations which is within the barrier envelopes should therefore be
indicated on the barrier drawing and should be considered when determining operational
limits for the well. The formation strength can typically be based on physical measurements
performed during drilling of the well, e.g. Formation Integrity Tests (FIT), Leak Off Tests
(LOT) or Extended Leak Off Tests (XLOT). The indicated formation strength can also be
based on tests done on core samples, results from downhole logs or correlations based on
historical field data. The type of value used to indicate formation strength can differ in
meaning and uncertainty (e.g. a FIT value has another meaning than a LOT value, a value
derived from a downhole log has a higher uncertainty than a value based on tests on core
samples), and it should therefore always be stated what the indicated formation strength is
based on.
The formation provides containment of reservoir fluids together with the well barrier
elements which constitute the barrier envelopes, but the properties of formation is not tested,
designed, monitored or known in the same manner as for a well barrier element, which have
12. OLF Recommended Guidelines for Well Integrity
No.:117 Date effective: 01.10.08 Rev. no: 1 Rev. date: 10.12.08 Page: 12
___________________________________________________________________________
defined acceptance criteria. There is currently no common understanding of what well barrier
element acceptance criteria should be used for formation to ensure that formation in a
meaningful and adequate way can be treated and defined as well barrier element in the same
manner as e.g. casing or production packers.
4.2 Reservoir(s) should be shown on the drawing.
The reservoir(s) should be shown on the drawing to be able to verify proper barriers. This will
also ensure that any zone isolation requirements are fulfilled.
4.3 Each barrier element in both barrier envelopes should be presented
in a table along with its initial integrity-verification test results
By presenting each barrier element in the table, there will be no doubt regarding which
elements are a part of the barrier envelope. In addition, this exercise will help the engineer to
ensure the actual elements are qualified according to requirements and the ability to verify the
integrity of each element.
It is intended that the actual test results that verified the integrity is presented. For example
pressure test and CBL are methods used. The actual results should be presented.- e.g. pressure
test to 320 bar, FIT to 1,79 sg EMW, 100% bond at 3000 mMD.
When the well is completed, it is important to keep data and status of the well barriers. By
stating the actual integrity-verification method and test results for each element on the well
barrier schematic, the status of the well is known and documented. This information is also
important for the operational phase and later interventions and/or workovers.
4.4 Depths to be shown relatively correct according to each barrier
element on the drawing
It is important that the drawing show the barrier elements at the correct depths relative to each
other, and do not show e.g. that the production packer is set in cemented casing if the actual
layout is otherwise.
Likewise it is important to show the relative positioning of the reservoir(s) and the positioning
of the cap rock relative to the cement and production packer.
The relative positioning of the barrier elements is important in relation to integrity,
robustness, and the ability to detect any leakages after initial installation and testing.
For the same reason, it is also advised to show all packers, PBR’s and similar equipment on
the drawing.
The drawing should be well specific and show/illustrate the actual layout of the well.
4.5 All casing and cement, including the surface casing, should be on
the drawing and labelled with its size
For the same reason as above (4.4), it is important to show all casing sizes and the cement
behind. This will give important information of the robustness of the well, and not lead to any
misinterpretation of the design.
4.6 There should be separate fields for the following well information:
Installation, well name, well type, well status, rev. no and date, “Prepared
by”, “Verified/Approved by”
13. OLF Recommended Guidelines for Well Integrity
No.:117 Date effective: 01.10.08 Rev. no: 1 Rev. date: 10.12.08 Page: 13
___________________________________________________________________________
It is important that the well specific barrier schematic contain information about the validity
of the drawing. Therefore installation name and/or field name should be clearly stated, and
the name of the well.
To be able to understand the well barriers the "well type", if the well is an oil producer, water
injector, gas injector etc, should also be stated.
The status of the well, e.g. if the well is operational, shut in, temporary plugged for nippling
etc should also be defined. This is important such that the validity phase of the well barrier
schematic is clearly defined.
Document and quality control is needed. Revision number, date, information about who has
prepared, and who has verified or approved the schematic is therefore also needed.
4.7 Include a Note field for important well integrity information
Special well conditions that have changed the barrier envelope over time and other important
well integrity information should be highlighted. This ensures any weaknesses are made
aware of, and also shows the actual situation.
References to where the integrity dispensations are located (e.g. number) should be made,
with a short explaining text.
The WBS should be updated when well conditions such as e.g. detected tubing/casing leaks,
have changed the barrier envelope.
Other important well integrity information that has not changed the barrier but still should be
highlighted in the note field could e.g be leaks outside the barrier envelope.

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
15.15 Coffee and networking break
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.
