“…In general, it is difficult to identify if the minimum principal stress is vertical or horizontal stress without mapping the actual hydraulic fracture induced. Another drawback of the xLOT procedure is that one cannot determine the maximum principal stress magnitude (Lin et al 2008) which is also difficult to determine in standard HF (Ito et al 2007). Recently, Couzens-Schultz and Chan (2010) gave an alternative interpretation of LOP.…”

“…A drawback of the XLOT procedure that we have recommended is that it cannot be used to determine the magnitude of maximum principal stress, which is also difficult to determine using the standard hydraulic fracturing test (Ito et al, 2007). second and third test cycles are unnecessary, as a reliable , as a reliable as a reliable measure of the minimum principal stress will not be possible.…”

To understand the physics of faulting and rupture propagation for the great M8-class Nankai earthquakes that recur approximately every 100 years, a comprehensive drilling project is underway: the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE; Tobin and Kinoshita, 2007), which is part of the Integrated Ocean Drilling Program (IODP). Stress levels along seismogenic faults must be known in order to understand processes controlling the timing, energetics, and extent of earthquake ruptures. For scientific drilling projects such as NanTroSEIZE, it is very important to determine the in situ stress state at the decollement and the mega splay fault in the Nankai Trough

Knowledge of in-situ stress state in oil and gas reservoirs is necessary and important for the prediction of orientations of hydraulic fracturing and for the design of optimum parameters of the hydraulic fracturing aimed at enhances of hydrocarbon energy resource recovery. Although many types of stress measurement techniques have been suggested and developed up to today, there is not a perfect and reliable method for obtaining the full stress state information the three-dimensional stress tensor in a large depth well. For better understanding to the present situation of stress measurements and their insuf ciency, we reviewed and summarized the existing stress measurement methods which can be applied into a deep wellbore. In principle, measuring of the in-situ stress under in-situ condition is better; for example, applications of the hydraulic fracturing, leak-off test or extended leak-off test, as well as analyses of wellbore failure stress indicators including borehole breakouts and drilling induced tensile fractures are desirable. In some cases, the hydraulic fracturing and/or leak-off tests are impossible and the wellbore failure stress indicators are not available. Even such stress data are available, they may be insufficient, for example, lack of the maximum horizontal stress magnitude. Therefore, the core-based stress measurements are useful as the complementary approach. We described the details of anelastic strain recovery ASR method and diametrical core deformation analysis DCDA method which are widely and frequently applied in the recent scienti c and engineering deep drilling projects as the core-based stress measurement methods. We concluded that these core-based methods are applicable and helpful in deep drillings related to the hydrocarbon energy resource recovery projects.
