Abstract: A variable position gas trap apparatus and method to separate gases entrained in drilling fluid in a tank. The apparatus includes a gas trap attached to a carriage and a frame attached to the tank. A lever moveable by the float rod, activates the control valve to raise or lower the carriage having the gas trap container attached thereto. A feedback control loop is responsive to changes in the level of the drilling fluid in the tank. A mechanism is provided to mechanically and automatically move the carriage with respect to the frame in response to the feedback control loop.

Abstract: A process to analyze fluid entrained in well boreholes. The process includes gathering trap gas samples from return of drilling mud at multiple depths. The process also includes the steps of subjecting the samples to mass spectrometry in order to determine mass to charge ratios data of hydrocarbons and analyzing the mass to charge ratios data in relation to depth or time. Samples from at least one other source may also be gathered and analyzed chosen from the group consisting of mud fluid analysis, cuttings backgrounds analysis and cuttings crush analysis.
