Online slickline course

Duration: 27 hours (delivered as 3 separate modules)

About this course

The aim of this training is to provide delegates with the theoretical skills essential in applying advanced slickline operations and slickline fishing practices. Completing this program will improve the delegate’s knowledge and level of competence when encountering the unexpected during slickline operations.

Delegates will enhance their knowledge of slickline procedures when encountering unusual situations, broaden awareness of slickline fishing equipment, methods and practices and master the key principles involved in slickline fishing. They will explore together fishing pre-planning and risk assessment, learn about proven fishing techniques and understand the importance of slickline pressure control equipment configuration. Delegates will also understand how to avoid slickline fishing operations through the use of correct equipment and proper completion design.


This course has been designed for:

  • Experienced slickline operators
  • Completion/ slickline engineers
  • Integrated service crews and supervisors
  • Slickline crews and supervisors

Course outlines

MODULE 1 – 9 Hours (delivered over 3 sessions)
Delivered as separate module.

Completions are often designed in isolation with little thought given to slickline and other well services interface. This can lead to well intervention problems. This 9 hour module, delivered over 3 sessions takes a generic completion and looks at the downhole equipment, from the wireline re-entry guide to the safety valve nipple. The following topics will be discussed:
– Single zone and multi-zone wells with appropriate downhole equipment
– Each item in the completion along with its matching slickline tool and its optimum design performance expectation.
– Common operational errors along with completion design solutions.
– Q&A session and test questions – end of module 1

MODULE 2 – 12 hours (delivered over 4 sessions)
Delivered as separate module.

The slickline itself is often just considered to be the transport medium for setting downhole tools. Often wire performance, maintenance and quality issues are ignored. Below is a day by day overview of course topics:
Day 1
– Understanding wire from the manufacture process to breaking strains.
– Chemical suitability.
– Optimum jarring performance, non-destructive and sample testing.
– Using the correct countered and pulley sizes for the wire in use.
– Advantages and disadvantages of various types and use of weight indicators.
Day 2
– Barrier control.
– Lubricator maintenance and associated equipment rig-up.
– BOP potential usage faults.
– Maintenance and inspection issues.
– Stuffing box care, maintenance and potential usage problems.
– Braided line rig-up, multi-ram BOPs, grease head and ball checks.
Day 3
– Toolstrings and configurations.
– High deviation toolstrings
– Power jars set-up, use, and limitations (spring and hydraulic jars).
– Accelerators (wire stretch simulators): when and how to use them and matching them to power jars.
– Basic running/pulling tools.
Day 4
– Explaining different locks and plugs.
– Optimising performance by preparation checks and correct running procedures.
– Overcoming equalising and pulling problems.
– Choosing the correct packings for downhole conditions.
– Other plug types.
– Bailers, hydrostatic and sand type – how to use them and safely unloading the contents.
– Q&A session and test questions – end of module 2

MODULE 3 – 6 hours (delivered over 2 sessions)
Delivered as separate module.

The following topics will be covered during this 6 hour module, delivered over 2 sessions:
Day 1
– Making the well safe after a wire break.
– Planning the fishing job.
– Why a ‘fishing job’ should not be attempted without the correct fishing equipment on site.
– Calculating the top of the wire in the well using wire fallback chart.
– Selecting the correct surface equipment for safe wire recovery using a generic completion
(or an example from a participant).
– Selecting the correct blindbox size for ‘boxing off’ the wire from the rope socket.
– Selecting the correct toolstring and jars.
– Techniques for ‘boxing off’.
– Choosing the correct wirefinder.
– Choosing the correct toolstring for the wirefinder and using an appropriate running technique.
– Finding the top of the wire, selecting the correct wireline grab size and type.
– Running the grab to ‘pick up’ the wire without ‘balling’ the wire, bringing the wire to the surface.
Day 2
– Safe handling of potentially multiple strands of wire above the BOP.
– Recovering strands until a single strand is left.
– Recovering the broken wire onto a slickline unit.
– Discussion on various fishing scenarios and example given of slickline fishing plan for a well with multiple slicklines to recover.
– Discussion on techniques for fishing wire with a downhole break and also ‘blown up the hole’ scenario.
– Various other types of fishing tools on the market and their use (when and how).
– Q&A session and test questions – completion of the course.
