Abstract
Embodiments of the present invention provide systems and methods for downhole sampling or sensing of clean samples of component fluids of a multi-fluid mixture. More specifically, but not by way of limitation, embodiments of the present invention provide for, amongst other things, separating downhole multi-fluid mixtures into an oil-based fluid, a water-based fluid and/or the like and sampling and/or sensing of the clean separated fluids. Such sampling or sensing may be provided by a downhole tool in accordance with some embodiments of the present invention and the downhole tool may be used for production logging, formation testing and/or the like.
