Abstract

In a method for quantifying a volumetric flow rate of a flow of drilling mud in a floating structure for subsoil drilling, a flowmeter and a detection device are provided on a floating structure for subsoil drilling. The flowmeter generates a flow signal. The detection device generates a heave signal representative of a vertical heave of the floating structure. A processor transforms the flow signal into a first spectrum in the frequency domain and the heave signal into a second spectrum in the frequency domain. The processor compares the first spectrum with the second spectrum, obtaining a resultant spectrum. The processor transforms the resultant spectrum into a resultant signal in the time domain. The processor determines a mean value of the flow signal, adds the resultant signal to the mean value, obtaining a quantification of a flow of drilling mud in the floating structure.
