✦ Synopsis
The ability to correctly partition the three-dimensional pore space network of a porous medium, e.g., a petroleum-bearing reservoir rock, into the physically significant bulges ( pores) and constrictions (necks) depends on our ability to identify and locate the necks in a 3-D reconstructed data set.
Simulated model media giving necks of known position and orientation in 3-D were used to validate the multiorientational scaming approach used in our work and to demonstrate that scanning from a single orientation cannot detect all necks and probably misses more than half of them. The required resolution of the data set for correct partitioning of the pore space as a function of the number of scanning orientations is established, which allows us to draw conclusions on the optimal number of scanning orientations to use. The multiorientational scanning
