Geologically constrained evolutionary geomechanical modelling of diapir and basin evolution: A case study from the Tarfaya basin, West African coast

We systematically incorporate burial history, sea floor geometry and tectonic loads from a sequential kinematic restoration model into 2D evolutionary geomechanical that simulates the formation of Sandia salt diapir, Tarfaya basin, NW African Coast. use poro-elastoplastic description for sediment behaviour viscoplastic salt. Sedimentation is coupled with flow regional shortening to determine porosity strength capture interaction between sediments. find temporal spatial variation in sedimentation rate key control on evolution system. Incorporation rates at location east leads final very similar observed seismic reflection data. also changes can significantly affect present-day stress state above Overall, incorporating data models provides insights parameters geologic systems. Furthermore, it enables more realistic models, which, turn, provide porosity.
