Effect of directional hydraulic fracture layouts on strata control: Insights into seismicity mitigation in thick-hard roofs

Directional hydraulic fracturing is widely applied to mitigate seismicity hazards in multilayered thick hard roof (THR) systems. To clarify the governing mechanisms and effectiveness of various fracturing layouts, a field-scale Finite Discrete Element Method model was developed with stratum-specific in-situ stress loading.
