Course Details

Objective

The participants would be made adequately aware of 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 those doubts clarified during the course period. Adequate value would be added to each participant and their performance would enhance when they got their jobs in oil fields.

Methodology

This course combines sound engineering, operation and maintenance principles, applicable standards and best industry practices for reliable and cost-effective process plant systems. Delegates will be encouraged to introduce problems of their own for discussion and analysis. Copies of all lecture materials, case studies and workbooks will be provided. Group discussions will be carried out on problems faced.  This training program is lecture- based and customized to the needs of the audience, providing meaningful experience for personnel that work in petroleum plants. Daily sessions include formal presentation, prepared in the Power Point, interspersed with directed discussions and case study. In addition to formal lectures and discussions, the delegates will learn by active participation through the use of problem-solving exercises, group discussions, analysis of real-life case studies etc. Many relevant videos will be shown during the training.

All attendees receive a course manual as a reference.
