Course Description

Introduction

The process of inserting a reel of continuous tubing into a well while it is still under pressure is known as coiled tubing. Equipment for coiled tubing is modular and portable, despite the fact that contemporary reels can support heavy loads and provide rapid setup times.

Rather than the TVD, the maximum working depth of coiled tubing is typically dictated by the quantity of tubing that can be spooled onto a reel. Since gravity is needed to keep the tubing travelling down the well-bore, highly deviated wells can lead to issues with coiled tubing, just like wireline. With the use of downhole "tractors," which remove the coiled tubing from the bottom, this can now be partially resolved. Numerous tasks, including nitrogen lifting wells, cleanup procedures, spotting acid at perforations, fishing activities, spotting cement, and PLT, can be accomplished with coiled tubing. 

This training session on Course N Carry will emphasise:

  • Equipment for coiled tubing
  • Well control apparatus
  • Use of coiled tubing
  • Workplace layout
  • Techniques for acidification and stimulation 

Goals

After completing this training programme, individuals will be able to: 

  • Oversee and carry out interventions using coiled tubing.
  • Boost overall efficiency of operations while using coiled tubing interventions 
  • Choose the downhole tools that are most frequently used and describe their purpose.
  • Utilise liquid nitrogen safely.

Training Methodology

Properly produced slides, together with some animation on pertinent subjects, will be used to provide this training course on wire line operations and practices. Each attendee will receive an electronic form in PDF format or a printed handbook with all the slides. Pre- and post-assessment tests on relevant topics are also included in the teaching approaches.

Impact of the Organization

The following will benefit the organisation (directly and indirectly): 

  • Workers with training exhibit higher levels of motivation and confidence.
  • Lower production costs: Because skilled workers can produce superior results, there are no hazards. 
  • Decreased labour turnover can be attributed to a sense of security that is brought to the workplace.
  • Employee participation in the transformation process is known as change management. 

Impact on Person

Employees will benefit from the following: 

  • Oversee and carry out interventions using coiled tubing.
  • Boost overall efficiency of operations while using coiled tubing interventions 
  • Choose the downhole tools that are most frequently used and describe their purpose.
  • Utilise liquid nitrogen safely.
