A well
intervention is any operation carried out on oil or gas well during its
productive life that alters the state of the well, provides well diagnostics,
or manages the production of the well.
Primarily
in this course, we are concerned with problems associated with the completion
string. Problems associated with the reservoir can be investigated and
evaluated using production logging and well test techniques. In general,
problems associated with the completion string can be classified into problems
which arise in the tubing bore and which can be corrected through tubing
operations and problems which necessitate the retrieval of the completion
string from the well.
This course will contain in-depth information on
the impact of workovers and completion design in maximizing field production
and increasing recoverable reserves. It also emphasizes the importance of well
interventions methods (slickline, Electrical line and Coiled tubing) during
life time of the well to keep well productivity under optimum conditions.
This course will feature:
Introduction to
the variable nature of well interventions
Best practices
of completion string design and installation
Identify Wireline
best practice and applications
Identify Coiled
Tubing applications
Appraise well
control barrier philosophy and testing during well interventions

Training Methods
How will this Training Course be Presented?
This well intervention training course will be
presented using properly designed materials, some and animation on relevant
issues. A manual containing all the slides and/or electronic form in PDF will
be delivered to each attendant. Teaching methods include several examples of
actual well intervention programs.
Organizational Impact
The organisation will gain, in sending their employees to attend
this training course, the following:
Reduction in the
cost of the well by proper selection of production string
Extending the
well life and control it, achieve the optimum production using well
interventions instead of normal rig operations
Ensuring the
well integrity and avoiding all risks during rigless operations
Personal Impact

well completion design
Learn the knowledge and skills
necessary to effectively and safely control a well during well
intervention operations
