Patent ID: 8150669

Claim:
A method of mapping a sedimentary basin comprising sedimentary layers and fractures, including an architecture and layer nature resultant from a deformation of subsoil over geological time, between a geological time t and a current time, with a grid representative of a current architecture of the basin being constructed, comprising the steps: constructing past architectures of the basin, from the current time to the geological time t, by deforming the grid to construct a succession of Lagrangian grids, using a three-dimensional structural restoration wherein the deformation of the basin is calculated by solving equations representing continuous media mechanics using a finite-element method; simulating geological and geochemical processes governing formation of a petroleum reservoir, the simulation being performed in the Lagrangian grids from the time to the geological time t; and mapping the sedimentary basin from the simulation to identify zones of the basin where hydrocarbons may have accumulated.
