INTRODUCTION:
After the initial completion, work-over is done to restart commercial production or injection, fix a mechanical issue with the well, or plug and abandon the well. When hydrocarbon production rates start to significantly decline, work-over activities are often started. Poor primary cementing or water/gas coning could lead to unwanted fluid output. In these workovers, the unintended water/gas generation is often controlled by a corrective cement operation.
Well completion is a process used to generate initial production from or injection into a well once drilling is complete. Depending on the type of finishing and the area, several completion processes will be used. For instance, flowing wells can be put into production by merely being perforated. In order to produce at cost-effective rates, low reservoir pressure areas frequently need an artificial lift mechanism (rod or submersible pump, gas lift valves, etc.).
OBJECTIVES
By the end of this online training course, participants will learn to:Â
- 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
ORGANISATIONAL BENEFIT
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
PERSONAL BENEFIT
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
