A method for estimating fluid volumes moved in compartmented areas of the subsoil, the method including the steps of a) performing a series of gradiometric measurement campaigns at pre-established time intervals in a survey field, in which the relative variation &#x394;Vof the fluid volumes contained in a corresponding compartmented area of the subsoil is known; b) determining, for each measurement campaign after the first campaign, a parameter Pbased on the entire survey area; and c) determining a variability law that correlates the parameter Pto the known relative variation &#x394;Vin fluid volumes in the compartmented area of the subsoil.

Method for the continuous up-dating of a bidimensional and tridimensional seismic image in depth in real time during the drilling of a well by using seismic velocity information comprising the initial definition of a velocity model and the subsequent re-iterative modification of this initial velocity model by integrating the geophysical data taken on the surface with the geological domain of the subsurface data obtained directly during the drilling of the well.

Method for continuous updating in real time of bidimensional and
