Abstract
In today’s 3D surveys, the volume of data can be overwhelming. It is essential to have methods that quickly identify<br>errors and/or bad data. Modern field QC uses seismic trace attributes (energy levels within specified windows, energy<br>decay factors, first arrival times) in combination with survey information (shot and receiver positions) to create new<br>quality control measurements and displays, Such QC displays can quickly pinpoint location and other errors at both<br>shot and receiver positions. Examples of verifying 3D geometry, energy decay maps, and finding posrtron errors will<br>illustrate the latest QC methods.
