Z-Terra North’s new 6-D Pre-Stack Interpolation (SPRINT6D Structure Preserving INTerpolation) is a novel interpolation technique designed on an improved Minimum Weight Norm Interpolation (MWNI) technique for seismic processing.  The 6-D Interpolation is a frequency domain Fourier inversion method, with a priori model constraints that guide the inversion process.  The constraints can be further enhanced by imposing an angular weight function derived from different dips of input data in the f-k frequency-wavenumber domain. 

SPRINT6D Interpolation has been used globally with very good results (several papers were published with respect to this process and the results), and the structure is always preserved when using SPRINT6D Interpolation.

Fourier domain reconstruction
Interpolates both signal and noise
Preserves structures and amplitudes
Same characters of existing and interpolated traces
Same structures with and without interpolation
Same AVO attributes with and without interpolation
Same AVAZ attributes with and without interpolation
Regularizes data
Improves S/N ratio
Harmonizes different vintages of data, i.e., 3D Merge
Helps multiple attenuation 
Stabilizes subsequent processes, e.g., PSTM, AVAZ/VVAZ
Enhances 4D analysis
Adds values to legacy datasets by achieving improved processing results
Works well with mega/slim bin geometries
