Understanding the existing seismic data used in your seismic survey design analysis is critical to the success of your seismic project.

The basic questions that need to be answered include:
1. What existing data do you have?
2. What is the vintage of the existing data?
3. What are the parameters of the existing data?

Answering these basic questions will prepare you for a successful seismic survey design.

The surface footprint of our seismic program will be significantly larger than the area of interest we want to image for our subsurface target.
Fold Taper: A buffer around the target area that is required to reach “Full Fold” for a given offset.
Migration Aperture: A buffer around the target area in order to correctly migrate dipping events to their true location and collapse diffractions.

IMPORTANT TAKEAWAY:
Adding a fold taper and migration aperture adds significant size to a seismic program, which means significant cost.
Do you need a full migration aperture? That depends on your imaging objectives.
