Course Description


Workover is performed after the initial completion to re-establish commercial production or injection, repair of a mechanical problem in the well, or plug and abandon the well. Workover operations are usually initiated as hydrocarbon production rates decline substantially. Undesired fluid production could be the result of a poor primary cement job or water / gas coning. These workovers typically involve a remedial cement job to control the unwanted water / gas production. 

Well completion is performed at the completion of drilling operations to establish initial production from or injection into a well. Procedures of completion will vary depending on the completion type and the area. For Example flowing wells can simply be perforated and put on production. Low reservoir pressure areas often require an artificial lift mechanism (rod or submersible pump, gas lift valves, etc.) to produce at economic rates. 

This GLOMACS training course will highlight:

  • Types of Completions
  • Reasons for Workovers and well preparation
  • Overview of Surface and Subsurface Wellbore Equipment and Procedures
  • Barriers, Completion and Workover Fluids
  • Kick Causes, Warning Signs, kill methods and Risk awareness and Organizing a Well Control Operation


By the end of this GLOMACS training course, participants will learn to:

  • Plan, design, manage and execute completion operation
  • Improve the overall operational performance during workover operations
  • Select or recommend completion equipment for given field conditions and applications
  • Select the most commonly used downhole tools and explain their function

Training Methodology

  • Introduction and pretest to evaluate the level of attendees to know the major points they do not know to cover it
  • Presentation with clear font and background including animation and videos
  • Exercise and round table discussion
  • Post Test to evaluate the level of attendees understanding after the course

Organisational Impact

Organization will gain (direct and indirect) the following:  

  • Employees who receive training have increased confidence and motivations
  • Lower cost of production – eliminates risks because trained personnel are able to make better
  • Lower turnover – brings a sense of security at the workplace which in turn reduces labor turnover
  • Change management –involvement of employees in the change process

Personal Impact

Personnel will gain the following: 

  • Supervise wok over operations
  • Improve risk awareness for workover and completion operations
  • Troubleshooting the well problems
  • Minimize downtime for well operations
  • Prepare full workover program


This GLOMACS training course is designed for those involved in the work over operations and completion design:

  • Production Technologists
  • Production Engineers
  • Operations Engineers
  • Field Technicians
  • Workover Engineers
