Abstract
A method is disclosed for initiating or causing fracture of an underground formation. An isolated interval, with an adjacent guard region at either or both ends is formed by a suitable packer assembly. Pressure and/or flow within the test interval is then increased to initiate fracture while conditions such as pressure and/or flow are monitored within the test interval and guard region or regions to detect fracture propagation relative to the borehole axis.
