Abstract
A method of fracturing an underground formation traversed by a borehole comprising: a) placing an inflatable member inside the borehole in the formation to be fractured, b) inflating the member so as to exert stress on the formation while monitoring the pressure of a fluid used to inflate the member so as to determine the pressure at which fracture initiates; c) isolating the portion of the borehole containing the fracture; d) propagating the fracture by pressurizing the interval with fluid; and e) monitoring the pressure of the fluid in the interval during propagation.
