摘要： Methods and systems are provided for quantifying contributions of gas mixtures in a reservoir compartment by way of isotopic analyses. Differing thermal maturities of the different gas mixtures allow estimation of the relative quantity of each gas mixture present in a total gas mixture. Thermal maturities may be estimated by reference to isotopic analyses of each contributing gas mixture and a commingled gas mixture resulting from commingling each of the individual source gas mixtures. This method may be carried out at various depths to determine relative contributions of each gas mixture to the total gas mixture as a function of wellbore depth. Advantages of certain embodiments include, but are not limited to, higher accuracies and ease of application as compared to conventional methods.

摘要： This method allows for prediction of subsurface fluid properties (e.g., phase or API gravity) using gas chromatogram data of a small-volume extract. Small volume equates to microliter scale volume (or milligram scale weight) from a subsurface rock sample, where a fluid test may not be available for analysis. The method may also be applied to petroleum liquid samples where drilling fluid or other contaminants preclude accurate direct property measurement. Gas chromatographic data is calibrated to measured petroleum properties; preferably local oils from the same petroleum system, however, a general global calibration can also be used.
摘要翻译： 该方法允许使用小体积提取物的气相色谱数据预测地下液体性质（例如，相位或API重力）。 小体积等于来自地下岩石样品的微量级体积（或毫克量级），其中流体测试可能不可用于分析。 该方法还可以应用于石油液体样品，其中钻井液或其他污染物排除准确的直接性质测量。 校准气相色谱数据以测量石油性质; 优选来自同一石油系统的局部油，但也可以使用一般的全局校准。
