1. OIL DERRICK
The rotary drill rig employs a series of rotating pipes, the
so-called drill string, to access an oil field. The chain is
supported by a tower, and the rotating bank of the base
rotates it. A sludge-like fluid, driven by a pump, removes
drilling debris as the drill penetrates the rock. Oil deposits
are formed as a result of intense pressure on layers of dead
aquatic and terrestrial organisms, mixed with sand or silt. As
they have no room to expand, gas and crude oil are under
great pressure, and have a violent outbreak through the
drilled hole.
