Method for forming a model of a formation geological, which is stressed by the dynamic and static

摘要

- method for forming by an inversion technique, a model of an underground zone, which is stressed by the static data: data obtained by seismic exploration or measured in situ (logs), and the dynamic data: measurements of production, tests of the well, etc... - from a meshed geological model chosen a priori and relations between the parameters or physical magnitudes characteristic of the medium: acoustic impedance, and absolute permeability, for example, a simultaneous reversal of the two parameters by minimising a cost function - overall, which has the effect of considerably reducing the number of possible solutions and to improve the characterization of the zone underground. - applications in particular in the modelling of hydrocarbon reservoirs, of zones that can be used as storage locations gas, the waste, etc, 1 / p
