Abstract:
1. An apparatus for sampling fluid from a formation comprising: (a) a tool conveyed on a drill string in a well borehole surrounded by the formation; (b) a fluid moving device at a surface location coupled to the tool for delivering a first fluid through the tool, the first fluid comprising a drilling fluid, the first fluid exiting the tool at a distal end and returning as a return fluid to the surface location in an annulus between the tool and a borehole wall, the return fluid including the first fluid and formation fragments; (c) a fluid-diverting device for directing the first fluid from within the tool toward a portion of the borehole wall for diverting the fragments in the return fluid away from the wall portion; (d) a pad member disposed on the tool, the pad member being moveable in relation to the wall portion for sealing said wall portion from the annulus; and (e) a first port exposed to the sealed wall portion for sampling formation fluid.
