Abstract
The invention notably relates to a computer-implemented method for analyzing a hydrocarbon trap, for hydrocarbon production. The hydrocarbon trap has a top surface. The method comprises providing one or more geological meshes each representing the top surface. Each geological mesh has cells each representing a location on the top surface. The method further comprises for each geological mesh, determining one or more cells on the geological mesh. Each determined cell corresponds to a respective saddle of the trap.

A computer-implemented method for analyzing a hydrocarbon trap in hydrocarbon production, the hydrocarbon trap having a top surface, the computer-implemented method comprising:
- providing one or more geological meshes, each geological mesh representing the top surface, each geological mesh having cells, each cell representing a location on the top surface, wherein each geological mesh comprises depth values, each depth value at a cell, and each depth value representing a depth of the location represented by the cell;
- for each geological mesh, determining one or more cells on the geological mesh, each determined cell corresponding to a local maximum of the depth values, wherein determining the one or more cells comprises:
- (i) providing two or more top cells on the geological mesh, each top cell representing a top of a respective culmination of the hydrocarbon trap and (ii) performing multiple propagations on the geological mesh, each propagation starting at a respective top cell and being performed according to a propagation criterion that rewards depth value smallness, wherein each determined cell corresponds to a respective saddle of the hydrocarbon trap representing a real-world location of the respective saddle;
- and
- based on the determined one or more cells, causing one or more physical actions in the hydrocarbon production at a given the real-world location of a given the respective saddle.
