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.
