Method for modeling a sedimentary basin

A method for modeling a sedimentary basin which has undergone a plurality of geological events defining a sequence of states of the basin, each of the states extending between two successive geological events, comprising:

• (a) obtaining measurements of physical quantities of the basin which are acquired from sensors;
• (b) constructing for each of the states a meshed representation of the basin having cells which are dependent on the measurements of the physical quantities;
• (c) computing for each of the states and for each cell of the meshed representation an effective stress applied to each cell at the end of the state;
• and
• computing an overpressure in each cell at the end of the state depending on the effective stress computed at the end of the state.

Equipment for modeling a sedimentary basin, which has undergone of geological events defining a sequence of states of the basin with each state extending between two successive geological events, the equipment being configured to:

• obtain measurements of physical quantities of the basin which are acquired from sensors;
• constructing for each of the states a meshed representation of the basin depending on the measurements of physical quantities;
• and
• computing for each of the states and for each cell of the meshed representation an effective stress applied to the cell at the end of the state and computing an overpressure in the cell at the end of the state dependent on the effective stress computed at the end of the state.
