WELL INTERVENTIONS Completion Design & Slick Line / Coiled Tubing Well Interventions Techniques
Details :
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 training 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 lifetime
of the well to keep well productivity under optimum conditions.
This training
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
By the end of this training course, delegates will learn:

the economic implications of a workover in terms of the need to protect
the well production or injection capacity.
- List
and describe the equipment and operational concepts involved in coiled
tubing and hydraulic workover units.
- Identify,
evaluate and recommend functional capability of completion strings for a
variety of situations
- know
the well control barrier principles
- Identify

- Know
well control barrier classification for different type of well
intervention method.
- Describe
the mechanisms of a slick wireline operation.
- List
and describe the commonly used downhole wireline equipment and tools.
- List
and describe the surface wireline equipment requirements; lubricator; BOP;
stuffing box.
