Abstract
A tank is fed with mud via a first inlet and the mud is removed via a first outlet. An ultrasonic electroacoustic transducer generates an acoustic energy field in the mud contained in the tank so as to extract the gases from the mud. A carrier gas is injected via a second inlet of the tank and a physico-chemical analysis apparatus of the extracted gases is connected to a second outlet of the tank designed for the carrier gas and the extracted gases. The flow rate of mud fed to the tank is regulated to a constant value and the volume of mud in the tank is constant. The mud can be constituted by oil prospecting drilling mud, the gases to be extracted then being oil revealing gases. The mud feed and injection of carrier gas can be synchronized so as to enable continuous analysis or batch analysis.
