Abstract:
1. A method comprising: providing voxels that comprise spatially distributed values for a first attribute representing characteristics of a subterranean formation and spatially distributed values for a second attribute representing characteristics of the subterranean formation wherein the first attribute and the second attribute comprise different attributes; setting a first control parameter to provide a first weight to weigh a threshold or to weigh values of the first attribute and setting a second control parameter to provide a second weight to weigh a threshold or to weigh values of the second attribute; from an initial seed of one or more of the provided voxels, iteratively selecting spatially connected voxels through a voxel selection criterion to generate an iteratively growing volume wherein the selecting applies the first and the second weights to comparisons between values and thresholds of the first and second attributes; rendering a visualization of the iteratively growing volume of spatially connected voxels to a display; halting the iteratively selecting to provide an iteratively grown volume of spatially connected voxels; adjusting at least one of the first control parameter and the second control parameter to provide at least one adjusted weight; from the generated iteratively grown volume of spatially connected voxels, iteratively de-selecting spatially connected voxels through a voxel de-selection criterion to generate an iteratively shrinking volume wherein the de-selecting applies the at least one adjusted weight to comparisons between values and thresholds of the first and second attributes; and rendering a visualization of the iteratively shrinking volume of spatially connected voxels to the display.
