ABSTRACT:
Methods of assuring that a representative formation and/or fluid sample of a subterranean reservoir is obtained are provided. One method of validating a reservoir fluid sample obtained from a wellbore includes the steps of acquiring a reservoir fluid sample in the wellbore; measuring a property of the fluid sample downhole with a technique to obtain a measured downhole fluid property; replicating the measuring technique used to obtain the measured downhole fluid property to obtain at a remote location from the wellbore with a technique to obtain at least one measured remote location fluid property; validating the fluid sample through comparison of the measured downhole fluid property and the at least one measured remote location fluid property.
