ABSTRACT: Stochastic Imaging of the Wilmington Clastic Sequence

A. G. Journel, J. J. Gomez-Hernandez

The geometric architecture of the sand-shale sequence in two layers of the Wilmington field is characterized by indicator variograms produced with noncartesian coordinates ensuring stratigraphic conformity. The sequential indicator simulation (SIS) algorithm produces several alternative equiprobably three-dimensional models of the sand-shale sequence, all of them honoring the data at their locations and reproducing the indicator variogram model. These alternative models provide a direct visualization of spatial uncertainty that can be used to assess the need for additional data.
