Geostatistic method is an effective approach in studying the distribution of spatial variation including regional variation
variation function
kriged estimate.In seismic data processing
static correction
superficial velocity
time difference
dip angle and curved ray may result in errors in interval velocity calculation.The geostatistic method could find the internal space variation regularity of interval velocity
restrain random error and improve signal noise ratio
thus correcting the error of seismic interval velosity.
