There is provided a method of sampling a subterranean formation. The method includes the steps of creating a side bore into the wall of a well traversing the formation, sealing the wall around the side bore to provide a pressure seal between the side bore and the well, pressurizing the side bore beyond a pressure inducing formation fracture while maintaining the seal, pumping a fracturing fluid adapted to prevent a complete closure of the fracture through the side bore into the fracture, and reversing the pumping to sample formation fluid through the fracture and the side bore.
