  • High accuracy contamination estimation in hydrocarbon samples using GC×GC
    Patent number: 7805979
    Abstract: A method of estimating contamination of oil based mud filtrate in a hydrocarbon sample. The method comprising the steps of obtaining a hydrocarbon sample contaminated with oil based mud filtrate, then analyzing the contaminated hydrocarbon sample using two-dimensional gas chromatography (GC×GC). The method further comprises identifying one or more unique component or tracer in the oil based mud filtrate in the contaminated hydrocarbon sample. Finally, the method comprises of summing the peak volumes of the one or more unique component or tracer, relative to the peak volumes of a clean hydrocarbon sample.
