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.

What is claimed is: 1. A method of obtaining a fluid sample from an underground formation traversed by a borehole, comprising:lowering a tool into the borehole, the tool including at least one perforation mechanism disposed through a sidewall of the tool, and at least one port fluidly connected to a sample container;creating a first hole through a borehole wall into the formation with the at least one perforation mechanism;increasing a mobility of formation fluid, wherein the formation fluid is disposed between the borehole wall and the first hole, wherein increasing the mobility includes engaging at least one of a packer and a pad against the borehole wall and activating a heating element disposed in the at least one of the packer and the pad; andobtaining a sample of fluid from the formation, wherein at least one of increasing and obtaining is performed utilizing the first hole.
