Abstract
Directional hydraulic fracturing (DHF) has been used in conductivity improvement of oil, gas and geothermal energy reservoirs and hard rock roof breaking in coal mines. Although the new DHF method that integrates fracturing borehole and slotted directional borehole (SDB) has been recently introduced, the mechanism and effectiveness of SDB on hydraulic fracture guiding remain open issues. In this study, numerical simulation based on extended...
