Method for determing distinct alternative paths between two object sets in 2-D and 3-D heterogeneous data

摘要

Distinct paths (40), e.g., locally optimal, are determined in a heterogeneous velocity field (32) between a source object and a target object (33) using gradients (35) of a two-way total arrival time field (34). The foregoing technique may be used to assess hydrocarbon reservoir connectivity.
