Even with no experience, it is possible to get a job working on an oilfield. Entry-level offshore positions include roles like roustabout, while you can work on a land-based oil rig as a floorhand. Entry-level oilfield jobs often involve drilling for oil or gas, helping move and maintain equipment, and otherwise helping other workers on the platform as necessary. Many employers use entry-level jobs as a type of extended training period to help you learn the tools and techniques required for other roles. Like most oilfield jobs, entry-level positions in this field involve frequent physical labor and long hours. Some oilfields allow new employees to operate heavy equipment after basic training.
