METHOD FOR THE ESTIMATION OF FLUIDS MOVED IN COMPARTMENTED AREAS OF THE SUBSOIL

摘要

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 &Dgr;Vi of 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 P1i based on the entire survey area; and c) determining a variability law that correlates the parameter P1i to the known relative variation &Dgr;Vi in fluid volumes in the compartmented area of the subsoil.
