Method to determine location, size and in situ conditions in hydrocarbon reservoir with ecology, geochemistry, and biomarkers

摘要

A method of identifying a hydrocarbon system is disclosed A sample from an area of interest is obtained. A first plurality of analyses is used to determine a community structure of an ecology of the sample. A second plurality of analyses is used to determine a community function of the ecology of the sample. The community structure and the community function are used to determine whether the ecology of the sample matches a characteristic ecology of a hydrocarbon system. When the ecology of the sample matches the characteristic ecology, the sample is identified as part of the hydrocarbon system.
