Drilling and Completion Chemicals in the Oil Course
Introduction:
Following the initial completion of a well, drilling operations may need to be conducted for various reasons, including the restoration of commercial production or injection, addressing mechanical issues, or permanently sealing the well ("plug and abandon"). Work-over operations are typically initiated when hydrocarbon production rates significantly decline. Unwanted fluid production, such as water or gas, may occur due to issues like an inadequate primary cement job or water/gas coning. In such cases, work-overs often involve implementing remedial cementing techniques to control the undesired water/gas production.
Course Objectives:
By the end of this 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 commonly used downhole tools and explain their function
