METHOD OF SEEKING HYDROCARBONS IN A GEOLOGICALLY COMPLEX BASIN, BY MEANS OF BASIN MODELING

摘要

A method for mapping a complex sedimentary basin is disclosed. A grid representative of the current architecture of the basin is constructed. A mechanical structural restoration is applied in three dimensions so as to reconstruct the past architectures of the basin from the current time up to a geological time t. A simulation of the geological and geochemical processes that govern the formation of a petroleum reservoir is then carried out, directly in the grids obtained from the restoration, from the geological time t to the current one. This simulation is thereafter used for mapping the sedimentary basin so as to identify zones of the basin where hydrocarbons may have accumulated.
