Course Details

Objective

The participants would be made adequately aware about the technology    inherent in each mode of artificial lift and they would be made fully conversant with their operational details. The working executives would be encouraged to get that doubts clarified during the course period. Adequate value would be added to each participant and their performance would enhance when they go their jobs in oil fields.

Methodology

A highly interactive combination of lectures and discussion sessions will be managed to maximize the amount and quality of information and knowledge transfer. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. You will also be encouraged to raise your questions and to share in the development of the right answers using your analysis and experiences.  Tests of the multiple-choice type will be made available daily to examine the effectiveness of delivering the course.

Very useful Course Materials will be given.

• 30% Lectures
• 30% Workshops and work presentation
• 20% Group Work& Practical Exercises
• 20% Videos& General Discussions
