Abstract: An intermediary well may be selected for a group of wells. The intermediary well may be used as an origin point from which branching wells paths are generated to connect the group of wells through the intermediary well. A shortest path between the intermediary well and the group of wells along the branching well paths may be identified, and the group of wells may be aligned along the shortest path. Boundaries of the intermediary well may be propagated to the aligned group of wells to establish correlation between segments of the intermediary well and segments of the aligned group of wells.

Abstract: A subsurface representation may define simulated subsurface configuration of a simulated subsurface region. The simulated subsurface region may include simulated wells, and the simulated subsurface configuration may define simulated correlation between the simulated wells. Subsurface configuration of wells may be compared with the simulated subsurface configuration to generate similarity maps for the wells. Simulated wells may be matched to the wells based on the similarity maps and the arrangement of the wells. Correlation between the wells may be determined based on the simulated correlation between the matched simulated wells.

Abstract: Correlation matrices may be used to simultaneously correlate multiple wells. A correlation matrix may be generated for individual pairs of multiple wells. The values of elements of the correlation matrices may be determined based on matching between segments of the multiple wells and segments of one or more computational stratigraphic models. An N-dimensional space including an axis for individual wells may be generated. Directed walk may be performed within the N-dimensional space to generate paths representing scenarios of correlations for segments of the multiple wells.
