The petroleum system of the subduction zone of Costa Rica was examined in a numerical basin modelling study. Three models with varying subduction velocities (30, 60, 90 mm/year) were calculated. The calculated temperature distribution shows that the temperature field is heavily disturbed in all models. The amount of subducted organic carbon is high due to the high-subduction velocity. Migration of oil and gas towards the sea floor does not occur due to the low migration velocities.
