This shows the raw data recorded by the two “listening” devices on the previous slide
The acoustic wave is recorded at device #1 at 0.4 seconds
The acoustic wave is recorded at device #2 at 0.8 seconds
To image the subsurface, we use hundreds of shots (explosions) and millions of receivers (listening devices) arranged in lines either on land or offshore
