Abstract: In some embodiments, a process can include obtaining a first formation fluid sample using a sample-line of a focused fluid sampling system and obtaining a second formation fluid sample using a guard-line of the focused fluid sampling system. The process can also include measuring a first optical density spectrum of the first formation fluid sample and measuring a second optical density spectrum of the second formation fluid sample. The process can also include decolorizing the first and second optical density spectrums to produce a decolorized first spectrum and a decolorized second spectrum, respectively. The process can also include normalizing the first and second decolorized spectrums to provide a first normalized spectrum and a second normalized spectrum. The process can also include determining a difference between the first and the second normalized spectrums to provide a sampling difference and adjusting a fluid sampling operation based on the sampling difference.

Abstract: Systems and methods of the present disclosure provide systems and methods for performing downhole formation testing operations. Certain methods include deploying a downhole toolstring of a downhole formation testing system to a downhole location within a wellbore extending through a subterranean formation, wherein the downhole toolstring includes a single packer positioned near a lower end of the downhole toolstring; setting the single packer within the wellbore to isolate one or more zones of interest of the subterranean formation in a lower portion of the wellbore below the single packer from an upper portion of the wellbore above the single packer; and, after setting the single packer within the wellbore, using the downhole toolstring to perform downhole formation testing on one or more fluids received from the one or more zones of interest by the downhole toolstring.

Abstract: Embodiments of the disclosure can include systems, methods, and devices for determining saturation pressure of an uncontaminated fluid. A technique facilitates fluid analysis in situ at a downhole location. Downhole saturation pressure measurements and downhole OBM filtrate contamination of a contaminated fluid may be obtained and a relationship may be determined between the saturation pressure measurements and OBM filtrate contamination. The relationship may be extrapolated to zero OBM filtrate contamination to determine the saturation pressure of the uncontaminated fluid. According to an embodiment, a sample of oil is obtained at the downhole location from oil in a reservoir. A downhole sampling system is used to determine whether a sample has contamination and other selected characteristics of the sample. The data obtained may be processed to provide a formation volume factor of the oil.
