Abstract
A formation fluid sampling tool is provided with a drill which drills into the formation in a manner perpendicular or oblique to the borehole wall. The tool comprises a mechanism for enhancing the mobility of the reservoir fluid, such as a heating element on the drill, hot fluid which is generated in the tool and injected into the drilled hole, or a solvent which is stored in the tool and injected by the tool into the drilled hole.
