What does a Fold of one mean in the context of seismic surveys?
What does a Fold of one mean in the context of seismic surveys?
- Each sub-surface point is sampled multiple times
- Each sub-surface point is sampled once (correct)
- There are no shot points adjacent to the receiver line
- The receivers are positioned randomly
Moving from 2D to 3D in a seismic survey means:
Moving from 2D to 3D in a seismic survey means:
- The area within the subsurface is now circular
- The fold decreases to zero
- There is no need for shot lines
- The area within the subsurface illuminated by the survey is now square (correct)

What does the Crossline direction refer to in a seismic survey?
- The direction perpendicular to the shot line
- An arbitrary direction chosen for data collection
