Abstract

It is described a method and a system for wireless in-situ sampling of a reservoir fluid from a hydrocarbon reservoir comprising obtaining a number of local samples of the reservoir fluid from different zones of the reservoir at given times. Local characterization of production fluid is obtained based on identifying chemical fingerprints of each of the number of local samples. This information can be used to determine local production rates from different zones in the well or from coming led wells.
