Abstract

See full text

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.
