Abstract

Hydraulic fracturing stress measurements cannot provide the magnitude of maximum compressive stress with sufficient reliability. To overcome the defect, a new loading probe that can generate a fracture plane in any desirable direction, was developed. The authors examined a borehole wall stress condition induced by the probe and simulated a pressure-displacement curve using a boundary element method. The laboratory experiments provided apparent acceptable results, however, this investigation elucidated that the results come from the fact that ignoring twice large stress concentration at a crack position was canceled out by misreading a re-opening pressure twice large. Thus, it was found that establishment of a method to determine a correct re-opening pressure is essential to make this
