Applications of Advanced Isotope Geochemistry of Hydrocarbons and Inert Gases To Petroleum Production Engineering

摘要

A system and method is provided for enhancing hydrocarbon production. The method and system involve geochemistry analysis and include multiply substituted isotopologue and position specific isotope geochemistry for at least one hydrocarbon compound of interest associated with free gas and sorbed gas. The method and system involve using clumped isotope and position specific isotope signatures to enhance monitoring of well and stimulation performance.

1. A method for enhancing hydrocarbon production comprising:
obtaining a plurality of hydrocarbon samples from a target subsurface interval; analyzing each of the plurality of hydrocarbon samples for geochemical signature comprising clumped isotope and/or position specific isotope geochemistry for at least one hydrocarbon compound of interest associated with free gas and sorbed gas; converting each of the clumped isotope and/or position specific isotope geochemistry signatures to a sorption dependent fractionation factor for each of the plurality of hydrocarbon samples; comparing the sorption dependent fractionation factor of at least two of the plurality of hydrocarbon samples; determining whether the at least one hydrocarbon compound of interest associated with free gas and sorbed gas has originated from the target interval or from a different interval; and adjusting a recovery strategy based on the determination.
