Abstract
The hexagonal sampling offers savings in data storage and processing of 3D poststack seismic data because the hexagonal sampling grid requires 13.4% fewer sample points compared to a square grid to represent data with the same degree of accuracy. Moreover, 3D poststack migration via McClellan transformations is better applied on a hexagonal grid than on a square one. Using a hexagonal grid of midpoints we can also reduce by 13.4% either the receiver or the source effort compared to a square grid of midpoints and yet still achieve the same resolution.
