Method to evaluate the hydrocarbon potential of sedimentary basins from fluid inclusions

摘要

A method for evaluating sedimentary basins for hydrocarbon potential using aqueous fluid inclusions. Aqueous fluid inclusions are identified in a rock sample. The homogenization temperatures of the fluid inclusions are determined, the optical spectra of the water and methane in the fluid inclusions are measured, and the formation pressures are estimated from the relationship of homogenization temperature and optical spectrum to formation pressure. Formation pressure of the fluid inclusions can be combined with history of the fluid inclusion formation to reconstruct the paleo-history of the basin to evaluate hydrocarbon potential.
