METHOD OF CONSTRUCTING A GEOLOGICAL MODEL
Method of constructing a geological model of a subterranean formation formed of at least two sedimentary beds. On the basis of sparse measurements of the geometry of boundaries of beds of a subterranean formation carried out on a grid, values of the geometry of each bed at any point of the grid are calculated according to at least the following steps: a succession of coarser and coarser grids is defined, constructed on the basis of the grid of interest; then, proceeding from the coarsest grid to the grid of interest, the geometry of the boundaries of each bed is determined by solving an inverse problem initialized with the result obtained for the previous coarser grid. Next, on the basis of the completed geometry of each boundary of beds on the grid of interest, the geological model of the formation is constructed. Application especially to the exploration and exploitation of oilfields.
