... ABSTRACT: In this paper, the principle of in-situ stress determination at great depth by using acoustic emission (AE) technique is presented. A new method is proposed to accurately measure the three principal in-situ stresses by means of re" peated loading on the core sample, based...

... of the important parameters that may be required for underground design. The "mini" hydraulic fracturing technique is now relatively well understood for in-situ stress determination. In this paper we present our initial effort to adapt this teehnique for permeability estimation. Although results are preliminary...

... of the fracture can often be used to determine the direction of the principal stresses. The advantage of hydraulic fracturing over the present in-situ stress determination methods is simplicity: no sophisticated instrumentation is required inside the borehole; hence, the stresses can be measured at any depth...
