BENEFITS OF THE CALCOULEE CONTINUUM 5D INTERPOLATION & REGULARIZATION
FREEDOM FROM ACQUISITION LIMITATIONS
The type of interpolation used by the Calcoulee Continuum software is not directly constrained by the surface
geometry. It attempts to create the ideal multidimensional trace spacing for the output CMP gathers regardless of the
imperfections that exist in the original survey.
IMPROVED RANDOM NOISE CANCELLATION
Improved random noise suppression is attained by the interpolation itself, since all the output traces are interpolated
and they are at regular intervals. The numerous weak spectral events required to express random noise tend to be
left behind. As well, spatial filtering noise attenuation algorithms may perform better on the regularized data.
IMPROVED ACQUISITION IMPRINT SUPPRESSION
The arrangement of interpolated output traces is not closely related to the surface geometry with this type of
interpolation. In addition, an ideal (regular and uniform) distribution of traces in offset and azimuth is created. These
two factors improve the suppression of acquisition imprint.
The Calcoulee Continuum 5D interpolation and regularization approach helps to stabilize horizon wavelets for prestack
and stack volumes. Because the approach suppresses random noise and acquisition imprint, and uses many input
traces to model each output trace, more accurate prestack horizon wavelets are achieved. Equal fold and regular
trace distribution in all dimensions further help to stabilize wavelet characteristics on stacked volumes.
