WORKOVER AND COMPLETION OPERATION

Why Choose this Training Course? 

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 work-overs 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 Galaxy Oil & Gas  Trainings course will highlight:

• Types of Completions
• Reasons for Work-overs and well preparation
• Overview of Surface and Subsurface Well-bore Equipment and Procedures
• Barriers, Completion and Work-over Fluids
• Kick Causes, Warning Signs, kill methods and Risk awareness and Organizing a Well Control Operation

Training Methods

How will this Training Course be presented? 

Participants will engage in a highly interactive learning experience, with a blend of class room learning, exercises, group work and discussion. The instructor will apply a range of proven adult learning teaching and facilitation techniques, which will address participants’ learning preference styles. Active participation is essential, to share experiences and expertise of the tutor, as well as the participants. We can all learn from each other.

Organizational 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 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
