I have done b.tech in petroleum as my branch ,how should i go ahead to get a well paid job?

Hi! As a petroleum engineer, you can find jobs related to oil and gas extraction, petroleum refining etc. You can find employment in companies that manufacture equipment and supplies for drilling and refining processes. you can go for the research field with the help of higher degree in petroleum

One of your options could be to search for jobs in the middle east countries in the oil exploration field. Options are more there. Other option is to work in a petrochemical refinery.
