Declarations under Rule 4.17: — as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(H)) — of inventorship (Rule 4.17(iv)) Published: — with international search report (Art. 21(3)) (54) Title: METHODS OF PREDICTING A RESERVOIR FLUID BEHAVIOR USING AN EQUATION OF STATE (57) Abstract: A method of using data ob­ tained from a sample of reservoir fluid a com­ prises: collecting the sample in sample a con­ tainer, wherein the sample container includes a sample receptacle, and wherein the step of col­ lecting comprises allowing or causing the sample to flow into the sample receptacle; de­ termining at least one compositional compon­ ent of the sample using an analyzer, wherein the step of determining is performed during the step of collecting; and using an equation of state to predict a potential change in at least one property of the reservoir fluid based on the determination of the at least one compositional component of the sample. Another method comprises: transferring the sample from the sample container to a second container, wherein the step of determining is performed after the step of collecting and during fluid flow of the sample.
