Abstract
A method of constructing a geological model of a subterranean formation formed of at least two sedimentary beds is described. Based on measurements of the geometry of boundaries of beds of the subterranean formation carried out on a grid, values of geometry of each bed at any point of the grid are calculated according to at least the steps of defining a succession of coarser and coarser grids, constructed based on the grid of interest; proceeding from the coarsest grid to the grid of interest, determining the geometry of the boundaries of each bed by solving an inverse problem initialized with the result obtained for the previous coarser grid. Next, constructing the geological model based on the completed geometry of each boundary of beds on the grid of interest.
