    摘要： A method of determining a presence and location of a subsurface hydrocarbon accumulation from a sample of naturally occurring substance. An expected concentration of isotopologues of a hydrocarbon species is determined. An expected temperature dependence of isotopologues present in the sample is modeled using high-level ab initio calculations. A clumped isotopic signature of the isotopologues present in the sample is measured. The clumped isotopic signature is compared with the expected concentration of isotopologues. Using the comparison, it is determined whether hydrocarbons present in the sample originate directly from a source rock or whether the hydrocarbons present in the sample have escaped from a subsurface accumulation. The current equilibrium storage temperature of the hydrocarbon species in the subsurface accumulation prior to escape to the surface is determined. A location of the subsurface accumulation is determined. This information may be integrated with pre-drill basin burial history models to calibrate a basin model.

    摘要： Systems and methods for determining geologic age are provided. A method includes separating a sample into species of interest; supplying the species of interest to a mass spectrometer; generating an intensity-versus-time data set for two or more elemental masses, identifying a set of intensity peaks having members from each of at least two of the intensity-versus-time data sets; and determining the geologic age of the sample using ratios of the members of the set of intensity peaks. A system includes a species generator for receiving a sample and generating species of interest; a mass spectrometer for receiving the species of interest and generating an intensity-versus-time data set for each of two or more elemental masses; and a processor configured to identify a set of intensity peaks, and to determine the geologic age of the sample using ratios of the members of the set of intensity peaks.

    摘要： A method of separating petroleum samples containing a hydrocarbon-soluble elemental species of interest to facilitate analysis of an elemental and/or isotopic signature. A petroleum sample is mixed with a demulsifier and separated, for example by centrifuging, into one or more intermediate organic fractions. The intermediate organic fraction(s) are mixed with a solvent such as water and a second demulsifier, then separated into one or more prepared organic fractions and one or more solvent-based fractions. Some or all of the resulting fractions are then stored for possible further processing. Optionally, the petroleum sample may be spiked with one or more of an organic standard and an inorganic standard, and the solvent may likewise be spiked with an inorganic internal standard, to facilitate later analysis.
