How to find oil traps 
Drilling is expensive. 
So 
oil 
companies 
plan 
carefully before they start 
drilling. First they make 3D 
maps of the rocks below the 
surface. Then they study these 
maps carefully. They look for 
possible oil traps. How do 
they make these maps? How 
do they find out what is below 
the surface? The answer is 
'seismic waves'. 
Seismic waves are sound waves, and they can travel through rock layers. 
Most oil companies use vibrator trucks to make seismic waves. These heavy trucks 
make vibrations on the surface, and the vibrations send waves down to the rocks 
below. 
Each rock layer reflects some of 
the waves. The reflected waves travel up 
to geophones on the surface. Geophones 
are like microphones: they convert the 
waves into electrical signals. A machine 
in the recording truck records the signals. 
Computers 
can 
convert 
these 
signals into 3D maps. Seismic reflection 
works at sea too. But the crews use 
hydrophones, not geophones, and they 
use an underwater gun to make seismic 
waves.
