Abstract: Hydraulic fracturing is a key technology to stimulate oil and gas wells to increase production in shale reservoirs with low permeability. Generally, the stimulated reservoir volume is performed based on pre-existing natural fractures (NF). Hydraulic fracturing in shale reservoirs with large natural fractures (i.e., faults) often results in fault activation and seismicity. In this paper, a coupled hydro-mechanical model was employed to investigate the effects of injection site on fault activation and seismicity… Show more

“…Fault slippage is a key factor in quantitatively evaluating the response of fracture propagation to fault activation (Chong et al, 2017). To illuminate the pattern for the fault to slip, two monitoring points M and N are set, with M Fig.…”

“…The remaining microscopic parameters of BPM and SJM were the same as Table 1 and Table 2. With references of the previous research [21][22][23][24][25], the microscopic parameters in the fluid calculation were shown in Table 4. In order to verify the numerical model of hydraulic fracturing, hydraulic fracturing tests were carried out under different initial in-situ stresses.…”

“…Thus, the DEM can simulate the crack initiation, propagation and penetration more realistically. The particle discrete element method, which is a distinct element-based model [15], has been widely used in rock fracture research [14,[16][17] and hydraulic fracturing [18][19][20][21][22][23][24][25]. Since unconventional oil and gas reservoirs, such as shale, have the distinct layered structure, the bedding planes will affect the initiation and propagation of the hydraulic fractures.…”

“…The Kelpperl well in Hugoton, Kansas, reported the first successful hydraulic fracturing in 1947. In hydraulic fracturing, the original cracks in the hard rock around the borehole are forced to expand by continuously injecting high pressure fluids [38][39][40]. Huang et al [41] studied the controlling factors of the breaking position of hard roofs and found that the optimal location should be located at the interior of the coal pillar.…”
