A better understanding of suballochthonous salt petroleum systems can be achieved by thermal modeling a series vertical pseudowell profiles that are positioned along ramps and flats identified at the base level. This allows changing 2D shape highly conductive to taken into account assesses physical parameters control evolution. case study typical cross section through Burgos Basin Perdido Fold Belt is analyzed in an area very active oil exploration northern Mexico. Numerical experiments indicated how extrusion cools underlying basin significantly prolongs period Tithonian source rock maturity. The rapid thick allochthonous sheets, associated transient heat flow effects, also cause peaks generation, places postdating trap formation during Oligo-Miocene folding event. principal predicted have remained window since Paleogene times, despite being buried present-day depths approximately 8 km subsea. upgrades potential some subsalt areas currently on offer CNH-R01-L04/2015 Mexico deepwater Licensing Round.
