Essential training for well completion and intervention operators and supervisors in wireline, coiled tubing and/or snubbing operations.
Scheduled courses
Description
This course develops the knowledge and decision-making skills required to operate (Level 3) and supervise or manage (Level 4) well intervention pressure control activities.
It builds on Level 2 and focuses on well integrity assurance, barrier management, pressure control methods, and response to abnormal situations.
The course is delivered through interactive lecturing supported by videos, animations, group discussions and exercises.
The two compulsory modules are:
Completions equipment
Completions operations
In addition, candidates must select at least one of the following three optional modules:
Wireline operations
Coiled tubing operations
Snubbing operations

Audience
Level 3 operator training is recommended for any role that is expected to shut in a well such as a operators in completions, well-servicing or intervention operations.
Wireline, e-line, slickline operator
N2 operator
Wellhead / tree installation engineer
Hydraulic workover (snubbing) operator
Coiled tubing operator and equivalent positions in other well servicing or intervention operations
Well test operator
Well testing crew
Level 4 supervisor training is recommended for all roles that oversee well control operations, either on site, off site, in a remote operations control centre or office based, in completions, and interventions. This includes personnel involved in both planning and execution of operations.
Completion / workover / intervention supervisor or superintendent
Well-site completions / workover supervisor
Supervisors or crew chiefs for special service operations such as wireline, slickline and coiled tubing operations, which provide specific well control equipment for these activities
Office-based operational staff (e.g., senior completions / well intervention engineer, operational completions / well intervention engineer)
Well test supervisor
Offshore installation manager (OIM) for offshore units with a primary function for well intervention
Hydraulic workover (snubbing) supervisor
Course Duration
5 days
Certification
Candidates must complete written exams for two compulsory modules:
Completions equipment
Completions operations
They also take exams in the optional modules that have been selected, which may include:
Wireline operations
Coiled tubing operations
Snubbing operations
A minimum score of 70% is required in each exam to pass.
IWCF WIPC Level 3 and level 4 certificates are valid for 2 years.
