I will be direct and to the point: working in the oilfield is a tough and dirty job. Expect to get your hands dirty, but keep in mind that the more you put in to your internship, the more you will get out of it. During my experience, I gained so much respect for the hardworking, intelligent men and women who work in this industry. Although we, as students, may be pursuing a degree in engineering, these are the people who have worked in the field and who have years of experience. Be respectful of this, and remember that everyone has something to teach you, all you have to do is listen.
