.... This paper focuses on the proppant properties and investigates how the proppant settling affects the propped fracture area. This paper also investigates how the presence of bedding layers affects the proppant transport and placement. The results indicate that the bedding layers can significantly affect...

... was presented. ABSTRACT: Anisotropy in the mechanical properties of rock is often attributed to bedding and mineral texture. Here, we use 3D printed synthetic rock to show that, in addition to bedding layers, mineral fabric orientation governs sample strength, surface roughness and fracture path under mixed...

... to plane of isotropy, or the bedding layers, and enhance the stiffness and strength in that plane. This new model can reproduce all the five independent elastic constants of transversely isotropic shales, which are all positive if the elastic in-to-out-of plane moduli ratio is<3.75 (this applies to all...

...) powderized shale, obtained by grinding to particle size of cca 0.5 to 0.85 mm. The core test is dominated by diffusion along the kerogen-filled bedding layers which are far more permeable than the rest, while the powder test is dominated by powder from the compacted clay rock between the bedding layers which...
