petroleum technicians measure and record physical and geologic
conditions in oil or gas wells, using advanced instruments lowered into
the wells or analyzing the mud from the wells. In oil and gas
exploration, technicians collect and examine geological data or test
geological samples to determine their petroleum content and their
mineral and element composition.
Some petroleum technicians, called
scouts, collect information about oil well and gas well drilling
operations, geological and geophysical prospecting, and land or lease
