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.

Petroleum-fluid property prediction from gas chromatographic analysis of rock extracts or fluid samples

This invention generally relates to natural gas and methylotrophic energy generation, bio-generated fuels and microbiology. In alternative embodiments, the invention provides nutrient amendments and microbial compositions, e.g., consortia, that are both specifically optimized to stimulate methanogenesis, or for 'methylotrophic' or other conversions. In alternative embodiments, the invention provides methods to develop nutrient amendments and microbial compositions that are both specifically optimized to stimulate methanogenesis in a given reservoir. The invention also provides methods for the evaluation of potentially damaging biomass formation and scale precipitation resulting from the addition of nutrient amendments. In other embodiments, the invention provides methods for simulating biogas in sub-surface conditions using a computational model.
