“…Damage zones are reported to act as conduits for fluids which enhance pore pressure diffusion, as opposed to the fault core that is cemented and have low permeability. The size of damage zone and its permeability is affected by coseismic damage (Yang et al., 2021) and interseismic healing processes (Yehya & Rice, 2020). Narrow damage zones exist in mature faults that have undergone healing or strain localization.…”

The response of critically stressed dormant faults to fluid perturbation, by oil and gas production, has been a major public concern because of its link to induced seismicity. In this paper, we study the hydrogeological factors that affect a nearby fault response, during and after hydraulic fracturing (HF) operations, evaluated by the change in Coulomb Failure Stress (CFS) and the rate of seismicity (R) through coupling solid deformation and fluid flow. Our results show that the pore pressure increases rapidly in a fault that is close (hydraulically connected) to HF operations, which might lead to its activation when the injection rate is high. When the fault is adjacent to HF but distant from it, its shallow region is subjected to a stabilizing deformation‐induced normal compressive stress and its deeper region is destabilized under extension. In this case, the fault orientation and damage zone size have a significant effect on the fault's stability and response. On the other hand, decreasing the rate of injection can either increase or decrease the CFS values depending on the fault location and the dominant stresses. Therefore, serious attention should be given to the fault position, its architecture, and the injection rate to help reduce the potential for induced seismicity from HF. Our findings are verified and confirmed using the case of the Duvernay formation in Alberta, Canada, where the reported seismic data correlate with high CFS and R values.

“…The faults that are formed open a fluid migration path (generally groundwater) to approach the heat source and or migrate to the geothermal reservoir zone (Anderson & Rezaie, 2019;Cheng, 2022;Geoffroy et al, 2022). Fault planes will generally increase porosity and permeability due to fractures formed between one fault plane and another Geoffroy et al, 2022;Riziq Maulana et al, 2019;Yang et al, 2021). The presence of faults that cause this fracturing can be identified based on the release of seismic waves generated when the fault is formed (Barbosa et al, 2020;Farhan et al, 2019;Firdaus Al Hakim et al, 2019;Küperkoch et al, 2018;Riziq Maulana et al, 2019).…”

Micro-earthquake (MEQ) distribution describes subsurface conditions that can contribute to monitoring the dynamics of geothermal reservoirs. Thus, the distribution of MEQ hypocenter locations with high accuracy becomes extremely important. Experiments were conducted with 3 variations of geometry and number of seismic stations, while Geiger and Coupled Velocity-Hypocenter methods were used to determine the location of MEQ. Experimental results show that in determining the location of the MEQ, the geometry and number of seismic stations played an important role. Increasing the number of stations with relatively long distances can result in less accurate locations of MEQ, error and bias in determining the location of MEQ will be greater when the azimuth gap value is greater. This is shown by the distribution of MEQ that are more spread out in variations 4A and 4B (4 seismic stations) compared to the distribution of MEQ hypocenters using data from 8 seismic stations. The azimuth gap variations of stations 4A and 4B are 283° and 267°, and 8 stations have a value of 222°. The large value of the azimuth gap is due to the distribution of stations only on one side so that there are horizontal angles that are not covered by seismic stations.
