Marginal data quality often makes interpretation of geologic structures from seismic data difficult and confusing. Because of these difficulties geophysicists have resorted to numerical and physical modeling, of which seismic modeling is an example, to help assess the data.

For survey design, 3D modeling by ray tracing has certain advantages over wave-equation modeling, such as cost and the ease of determining attributes, that are directly applicable to acquisition parameter decisions. For these reasons 3D modeling using ray tracing was chosen for the comparison, described in this article, of three 3D seismic survey designs (orthogonal, diagonal and brick). The ultimate choice...
