Work-over 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. Work-over 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 online training course on Work-Over and Completion Operations will highlight: 

• Types of Completions
• Reasons for Workovers and well preparation
• Overview of Surface and Subsurface Well-bore Equipment and Procedures
• Barriers, Completion and Work-over Fluids
• Kill methods and Risk awareness and Organizing a Well Control Operation

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

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

This online training course will utilize a variety of proven online learning techniques to ensure maximum understanding, comprehension, retention of the information presented. The training course is conducted online via an Advanced Virtual Learning Platform in the comfort of any location of your choice.

By attending this Work-Over and Completion Operations online training course, the organization will gain (direct and indirect) the following:

• Lower cost of production – eliminates risks because trained personnel can 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

By attending this Work-Over and Completion Operations online training course, the personnel will gain the following:

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