| 摘要 |
The present invention relates to a method for estimating fluid volumes moved in compartmented areas of the subsoil, including steps which consist in effecting, in a survey field, a series of gradiometric measurement campaigns “for framing/calibrating the area” at pre-established time intervals, for each of which the relative variation &Dgr;Vi of the fluid volumes contained in a corresponding compartmented area of the subsoil is known; on the basis of the measurement effected, to calculate, for each measurement campaign “for framing/calibrating the area” subsequent to the former one, a parameter Pu correlated to the whole investigation area; on the basis of the known fluid volume variations &Dgr;Vi and the relative calculated parameter P1i, to determine by approximation a variability law which relates the parameter Pu with the volume variation of the fluids in the compartmented area, associated with any measurement campaign subsequent to those for framing/calibrating the area on the basis of the variability law determined.
