Abstract (en)
[origin: EP2796663A2] A system and method for analysing gas from a borehole, the system comprising:- a degasser (20,120) configured to degas drilling mud to remove at least a portion of gas therefrom; an analyser (50,150), in gas communication with the degasser(20,120), the analyser (50,150) configured to analyse gas samples and provide information relating to the gas samples; the analyser (50,150) normally being a mass spectrometer(50,150); wherein the system is configured such that drilling mud is degassed in the degasser (20,120) for at least twenty seconds before at least a portion of gas removed therefrom is transferred to the analyser(50,150). The resulting batch analysis provides a number of important benefits. A degasser (20,120), cleaning mechanism, feedback system and mud heater (16,116) are also disclosed.
