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.

Analyzing a hydrocarbon trap

The invention notably relates to a computer-implemented method for processing a 4D seismic signal relative to a subsoil, the subsoil including a zone subject to extraction and/or injection, the method comprising: providing the 4D seismic signal; identifying a part of the 4D seismic signal corresponding to a zone of the subsoil distinct from the zone subject to extraction and/or injection; determining a noise model of the 4D seismic signal based on the identified part of the 4D seismic signal; and processing the 4D seismic signal based on the noise model. This improves the field of 4D seismic data processing.
