Abstract In this article, the contemporary stress state of Zhao–Ping metallogenic belt in eastern China was revealed using overcoring and hydraulic fracturing data, relation between field geological tectonics discussed, stability regional faults under present-day environment evaluated. The results indicate that level is considerably high, distribution intensity uneven. regime primarily characterized by σ H > v h . orientation well-oriented WNW–ESE, which roughly identical to other...
Abstract The stress measurements determined by both the overcoring (OC) and hydraulic fracturing (HF) methods in Shuichang iron mine Sanshandao gold were compared evaluated, respectively. results indicate that independent OC HF data two mines reveal same dominant faulting regime. σ H orientations derived from are dominantly oriented N81.1°W–N89.4°W N77.0°E–N88.0°E, respectively, yielded techniques predominantly N30°W–N90°W N55.5°W–N60.4°W, respectively; hence, obtained different...
Abstract The precise calculation and evaluation of the in-situ rock stress tensor is a crucial factor in addressing major challenges related to subsurface engineering applications earth science research. To improve accuracy measurement prediction, an improved overcoring technique involving circuit, temperature compensation, method presented for accurately measuring tensor. Furthermore, embedded grey BP neural network (GM–BPNN) model established predicting values. results indicate that has...
A large carbonate oil field in Iran is suffering from severe casing collapses and related operational problems anhydrite, marl salt sequences of the Gachsaran cap rock formation. To investigate causes cures problems, specifically collapse, knowing geomechanical properties this formation a prerequisite. However, taking cores virtually impossible due to high solubility weakness rocks. Moreover, there are insufficient well log data only available running Vp. In paper, order obtain dynamic...
Abstract. Fibre-optic sensing technology has recently become popular for oil and gas extraction, mining, geotechnical engineering, hydrogeology applications. With a successful track record in many applications, distributed acoustic using straight fibre-optic cables method of choice seismic studies. However, cannot detect off-axial strain at high incident angles (the angle between the ray normal vector surface); hence, helically wound cable design was introduced to overcome this limitation....
ABSTRACT: A crucial aspect of rock engineering design for deep mining projects is comprehending the in-situ stress field. This particularly true panel cave mining, where excavation and support extraction level tunnels pillars must account an initial increase related to their development subsequently abutment resulting from undercutting initiation. Thus, measurement should extend beyond establishing pre-mining state continuous monitoring evolving field, spatially temporally, throughout...
Abstract. This paper presents selected results of a broader research project pertaining to the hydraulic fracturing oil reservoirs hosted in siltstones and fine grained sandstones Bakken Formation southeast Saskatchewan, Canada. The contains significant volumes hydrocarbon, but large-scale is required achieve economic production rates. performance fractures strongly dependent on fracture attributes such as length width, which turn are in-situ stresses. reviews methods for estimating changes...

With a successful track record in many applications, distributed acoustic using straight fiber cables method of choice seismic studies. However, is not able to detect off-axial strain, hence helically wound cable design was introduced overcome this limitation. The field data New Afton deposit showed that the quality tightly dependent on incident...
