A good interpreter knows the basics of seismic survey design and can recognize problems when they arise. Even a well-designed survey can be ruined by sloppy acquisition methods. Common culprits are poor positioning or cabling information (i.e., which receivers are live for which shots).

Common culprits are poor positioning or cabling information (i.e., which receivers are live for which shots).

A3-D seismic survey is designed to give optimum results for a particular depth interval containing the target(s). If there are design, acquisition, or processing problems, then the data may contain artifacts. These are most commonly seen as map-view amplitude patterns and are called an acquisition footprint. One should [[avo]]id footprints because they can mask or confuse geologic patterns in the data.
