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.

Abstract: Disclosed is a method for identification of malfunctioning of a drill bit during drilling of hydrocarbon wells. The method includes measuring the penetration rate of the drill bit, measuring the drilling length, measuring the drilling mud concentration of at least one alkene gas species, measuring the torque at the drill bit, then analyzing the microscopic structure of the drilling cuttings on the basis of the values assumed by these measurements and on the basis of the observations of this microscopic structure. Finally the method generates an alert signal and returns the drill bit to the surface. The method facilitates a system for the early identification of drill bit malfunction due to wear, both in the case of fatigue and in the case of wrong initial choice of the type of drill bit with respect to the lithology of the rocks to be drilled.
