Abstract:
A method for forming a kinematic model allowing reproduction in 3D intermediate geometries of geologic objects of an underground zone, between an initial state and a known final state, the geometry of the geological objects of the zone being determined to be in the final state by interpretation of acquired data obtained by seismic exploration, by in-situ measurements and by observations, comprising the steps of:a) subdividing each geologic object in the initial state thereof into layers, each layer being defined by a grid pattern into a series of hexahedral volume elements; b) applying separately and successively tectonic deformations to each series of the hexahedral volume elements of a layer in relation to an underlying layer with conservation of the thickness of the layer and conservation of the surface area of an intermediate neutral surface in each volume element so as to obtain a geological representation; c) comparing the geological representation and the final state of the underground zone; and d) iteratively modifying the initial state and repeating steps a) to c) until a geological representation substantially best fitting the final state of the underground zone is obtained.
