I am a process operator for a petroleum refinery but I have always loved to become a production engineer in the upstream part of the business. I already have a 4yr college course work and currently planning on pursuing a bachelors in mechanical engineering but I don't know if my experience as an operator will be considered experience for engineering position after graduation. Is it really possible for a process operator to switch to engineering( production engineer/ drilling and completions or facilities engineer), what are the pros and cons. Please I need your advice.
