What refinery operators do

Refinery operators turn crude oil into gasoline, diesel, jet fuel and other products. They control distillation, cracking and treating units from control rooms, make field rounds, adjust temperatures, pressures and flows, take samples, gauge tanks and coordinate shipments by pipeline, ship and truck.

Most operators have a high school diploma and train on the job, though many refineries prefer a process technology associate degree. Pay is high, with overtime common. Employment is projected to decline slightly.
