Modelling of temperature distribution around salt diapirs :application to hydrocarbons assessment

Finite difference methods have been used to calculate the temperature distribution in the surrounding sediments of a salt diapir. In this model, results are in agreement with the work of Jensen, P.K. (1983). The temperature distribution around the salt diapir depends on the scale and its geometry; therefore, salt domes show a temperature gap above and beneath of them. The model presented here shows that the major positive anomaly of temperature above the salt dome is around 22-25°C, while the lowest anomaly varies from -20 to -25°C some meters beneath the bottom of the dome. Hence, in the presence of salt domes the maturity of the sequence changes, so hydrocarbons will be generated at a different time in the thermal history of the basin if salt domes are present. The case of Santos basin at Brazil shows the change in the rate of maturity; therefore, the potential reserves of oil increased in this country. Finally, it is important to study temperature anomalies because this phenomenon could explain the discoveries in ultra-deep water of Gulf of Mexico and some exploratory wells in Africa, allowing an increase of oil potential around the world
