As the anisotropy index of the elastic parameters increased, the effective stress increased and was deflected at a certain angle. The effective hoop stress was skewed toward higher stiffness, and the shear failure area gradually decreased...

The goal of this study is to evaluate anisotropic mechanical properties of shale by tri-axial tests and predict shale anisotropic properties by well logging data interpretation. Shale mechanical properties (Young's Modulus, Shear Modulus, and Poisson's Ratio) of different bedding plane...

... ABSTRACT We investigate horizontal stress variation in the vicinity of the deep-seated Balarud Lineament in the northern part of Iran's Dezful Embayment in the Zagros Fold and Thrust Belt (ZFTB). Both petrophysical data from drilled oil and gas wells (3-4 km deep) and earthquake focal plane...

In addition, considering the RF stress state in the Baong formation and the bedding planes that dip at about 30°, horizontal hydraulic fractures can form propagating in all...

... ABSTRACT: Bedding plane properties influence the failure behavior of laminated rocks such as slate and shale. For safe and stable underground coal mine design it is imperative to understand the relationship between the bedding plane strength and the failure of laminated rock. However...
