Controlled crack propagation has been a goal for better understanding of the mechanism of rock failure. The development of servocontrolled testing machines have brightened the horizon of research. By controlling other parameters besides the usual increase of pressure, and feeding the signal back, one is actually able to follow the fracture step by step. However, the amount of fluid present in a typical hydraulic fracturing test introduces a softening element into the high rigidity of the system. A miniature straddle packer of 1 inch diameter was developed to achieve the stated goals.
