Roughnecks weren't always brutes — the term comes from Texas and used to just refer to a “rugged individual.” Then it was a word for someone who worked on an oil rig. But now a roughneck is someone, usually a big man, who's tough, crude, and ready to fight. Roughnecks are the opposite of mild-mannered people.

Kinds of oil rig include: Drilling rig, an apparatus for on-land oil drilling. Drillship, a floating apparatus for offshore oil drilling. Oil platform, an apparatus for offshore oil drilling.
