Paper Number: ARMA-2021-1166
..., and the determination of different breakdown pressures and stress orientations for each formation. After inducing the primary fracture, the sleeve pressure continued to increase until a secondary fracture occurred. Correlation of pressure measurements and the fracture opening and closing events detected by the fiber...

... the shear fracture is initiated, but further mechanical shear resulted in permeability reduction. This work confirms that hydroshearing is possible at the Experiment 2 (4100 Level) site, but it requires a very weak preexisting fracture in addition to a shear-favorable orientation. Most of the observable...

... investigating the anisotropic stiffness and poroelasticity of the North Sea Draupne shale. From undrained triaxial compression tests on samples with different orientation relative to rock layering, a trend of increasing stiffness and less pore pressure generation is seen on samples oriented parallel...

Paper Number: ARMA-2021-1799
... ABSTRACT: This study combines novel and previously published data to create a new method of estimating anisotropic rock-mass strength in three dimensions that considers both the orientation and the non-persistence of multiple joint sets. Equations are developed to evaluate joint persistence...

... rose diagram. The study showed the existence of four families of fractures, of which the most abundant are in N-S and NW-SE directions. It was observed that the length, orientation and frequency of the fractures are closely related to the deformation of the main deformation band. The dilatation...

... Caledonides (Sweden). Through the comparison with other methods also implemented on these sites, we find that one SIMFIP test may be "sufficient" to estimate the full stress tensor's orientation and magnitude. We also observe that when a natural discontinuity activated, its properties must be considered...

ABSTRACT: Variations in the direction of the maximum horizontal compressive stress (SHmax) may significantly change the potential of faults to slip, especially if the SHmax orientation changes over relatively small distances. To estimate the potential for slip on mapped faults in the Delaware...
