Abstract: Fluid analysis measurements may be performed during withdrawal of a downhole tool to the surface. Fluid may be collected within a fluid analysis system of the downhole tool and the collected fluid may be exposed to the wellbore pressure during withdrawal of the downhole tool. Measurements for the collected fluid, such as optical density, the gas oil ratio, fluid density, fluid viscosity, fluorescence, temperature, and pressure, among other, may be recorded continuously or at intervals as the downhole tool is brought to the surface. The measurements may be employed to determine properties of the collected fluid, such as the saturation pressure and the asphaltene onset pressure.

Abstract: A method includes conveying a wireline toolstring into a wellbore to perform a downhole operation, wherein the wireline toolstring has a single packer disposed thereon. The method also includes positioning the wireline toolstring in the wellbore adjacent a zone of interest, wherein the zone of interest has a barrier is located at one end of the zone of interest and the wireline toolstring is positioned such that the single packer is located adjacent the zone of interest such that the zone of interest is between the single packer and the barrier. The method can also include setting the single packer and performing a wellbore operation.
