    摘要： 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.

    摘要： A method and apparatus detects dew precipitation and determines dew precipitation onset pressure in a sample of formation fluid located downhole in an oilfield reservoir. In a preferred embodiment, the method includes (a) isolating a sample of formation fluid downhole; (b) illuminating the sample downhole with fluorescence excitation light; (c) measuring at least one characteristic of fluorescence short from the sample; (d) reducing pressure on the sample; (e) repeating steps (b) to (d); (f) detecting dew precipitation when a change is detected in a parameter that is a function of the at least one characteristic of fluorescence emission; and (g) setting dew precipitation onset pressure equal to pressure on the sample when the change in the parameter is detected. The parameter preferably is a function of fluorescence intensity and fluorescence red shift, and the change is an increase in fluorescence intensity and detection of fluorescence red shift. Also, the function includes a ratio of a measured intensity at a first wavelength to a reference intensity, and the reference intensity is a function of a measured intensity at a second wavelength.
