<p>Bedding planes in sedimentary rocks influence hydraulic fracture propagation, often resulting in complex fracture networks. The interaction patterns of these bonded frictional discontinuities with hydraulic fractures vary depending on factors, such as interfacial bond and frictional strengths. In this study, we utilized the semi-circular bend (SCB) tests with varying interfacial bond strengths to experimentally analyze their impact on fracture trajectories. Additional factors, including the spacing and orientation of discontinuities, were also assessed. Strain and stress fields ahead of the crack tip were analyzed using Digital Image Correlation (DIC).</p><p>Fracture diversion was more likely for smaller approach angle and wider spacing. An increase in interface dip angle, spacing, and number promoted longer fracture diversion distance. A decrease in interfacial bond strength resulted in a greater debonding area within the interface before the fracture reaches the interface and ultimately longer fracture diversion and step-over length. DIC results revealed that the strain and stress concentrations were developed at the interfaces confirming the failure ahead of the fracture tip before the fracture encountered the interfaces. These findings are significant for understanding the influence of bedding plane characteristics on fracture propagation and height containment.</p>
