.... A novel closed-form pseudo three-dimensional (3D) approximation captures thermal, poroelastic, hydraulic, and mechanical effects (TPHM), visualizing the stress distortion at the intersection between the wellbore and a perforation tunnel. While specific formations like the Bakken Shale may present unique...

... ABSTRACT Unplanned roof falls in tunnel intersections are commonly associated with casualties, accidents, economical loss and therefore pose a serious threat for coal mine profitability. Despite the technological advance in ground control, fall of ground (FoG) in tunnel intersection often...

... ABSTRACT This study aims at improving our understanding on the stress field dominating the intersection between two tunnels of different diameter and hence provide insights on the stability against shear failures in this vicinity. Theoretical modeling of the deformation of rocks...

... of mining excavations is frequently controlled by rock discontinuities (Hoek et al., 2000). Wedges are formed by the intersection of more than two discontinuities on the walls of an underground opening. The structurally defined rock blocks can fall or slide toward the excavation. The most common wedges...

... and the geometric characteristics of the intersection. Simulation results of the different models were compared, which show that the intersection significantly impacts the relationship between the hydraulic gradient and the flow. Therefore, the pressure gradient increases with the decrease of the intersection angle...

... ABSTRACT: The intersection of the pre-existing natural fractures (NF) with the hydraulic fractures (HF) forms a complex fracture network, which allows for increased well productivity. However, the complex fracture geometry may adversely affect the proppant placement and its transportation...
