Petroleum engineers work in a highly technical field that involves extracting oil and gas from the land. While some of the designing and development work takes place in an office, petroleum engineers often travel to drilling and well sites to oversee the extraction process. Texas employs the highest number of petroleum engineers in the country, at 17,840 workers. Alaska and Oklahoma are two other major hubs for this field.
