Artificial Lift

By Prof. Abdus Samad | IIT Madras

Learners enrolled: 632 | Exam registration: 55

ABOUT THE COURSE:

The course contains the oil and gas pumping mechanism when the reservoir pressure is low, and it is required to enhance production using artificial means. The wellbore can have liquid loading problems, or fluid can have higher viscosity or corrosive chemicals, and the pumping of such wellbores needs special attention. Through this course, the students will learn different artificial lifts such as sucker rod pumps, electrical submersible pumps, gas lifts etc. After completing the course, the students will be able to size and select an artificial lift for a specific wellbore.

INTENDED AUDIENCE: Senior Undergrad or PG Petroleum, Mechanical and Chemical engineering students

PREREQUISITES: Basic knowledge of fluid mechanics, completed at least 2nd year in Engineering.

INDUSTRY SUPPORT: ONGC, Upstream, Baker Hughes, O&G companies

Registration url: Announcements will be made when the registration form is open for registrations.

The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.

Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Madras .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
