In this exhibit one sees how oil reservoirs are found through the method of Seismic sounding.
Seismic sounding is the technique most often used to find new oil reservoirs. The reservoirs are found by directing sound pulses vertically into the earth, and measuring how long it takes for the sound waves to return. The return of the sound waves then indicates if there is a reservoir underground, and how deep it is located.
- Choose a wagon and press its button.
- Observe how the sound waves are sent into the ground, and how long it takes before they return to the surface.
- Try the other wagons, and find out which one is situated closest to an oil well.
