Onsite reservoir fluid properties evaluationOnsite reservoir fluid properties evaluation Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-281990enThis paper describes a new method, the fluid properties estimation (FPESM),that can be used at the wellsite to provide realistic predictions of PVT andphysical predictions of PVT and physical properties of the reservoir fluidduring properties of the reservoir fluid during testing. Simple and rapidmeasurements of key fluid properties and onsite compositional analysis of theproduced fluid are input data for an produced fluid are input data for anequation-of-state (EOS) -based thermodynamic model. The simulator is tunedprimarily by regression to match the measured data and is subsequently used topredict the phase behavior and PVT properties of fluids produced at reservoir,well, and produced at reservoir, well, and surface conditions. The method,which is currently applicable only to oil reservoirs, has been successfullytested in several areas of the world. Examples given compare on-site FPEpredictions with full PVT studies performed in the laboratory. performed in thelaboratory.
