Geophysics: A Simple Guide to Volumetrics

Of several deterministic depth conversions, a preferred one is often referred to as a 'base case'. If kriging is used as the method of residual mapping then, in addition to the depth conversion uncertainty summarised by the residuals, an estimate of the interpolation uncertainty is also obtained from the kriging standard deviation. A kriging approach combined with a conventional …
