Oil well drillers operate drilling rig components to drill wells according to client or job specifications. Entry level drilling positions are generally entirely unskilled labor. With more training and experience, an oil well driller can become a leader of a drilling team, controlling the rate and continuity of drilling progress. They must have knowledge of how the drilling equipment works and occasionally need to carry out repairs and maintenance. Some drillers focus exclusively on vertical well drilling, but others venture into the more complex field of directional drilling, i.e. drilling wells on a slant. Their work is mainly done outdoors so there can be some harsh working conditions--extreme temperatures and confined spaces, for example.

Lower and raise drill pipes and casings in and out of wells.
Monitor pressure gauge and adjust throttles and levers to control the speed of rotary tables.
Set up and operate drill to remove underground oil or core samples for testing.
Monitor, maintain, and adjust machinery for optimal performance.
