... in the various sections of the Buckinghorse Formation. The results were comparable at the 0° and 90° orientation while the 45° orientation showed anomalous failure patterns prompted by the slippage/shearing along bedding planes, and demonstrated that there is a dominant change in the failure mechanisms when...

... fault / lineament model and the NF interpretation from borehole images and core data. Additional observations from drilling (e.g. losses) were used. Integration of NF data with borehole breakouts helped understand the relationship between NF orientation and productivity. An iterative procedure was used...

... of natural fractures. Over 500 cemented fractures per 1,000 lateral feet were recognized, and the relationship between the fracture and its fill composition, morphology, bitumen distribution, and orientation angle relative to bedding can explain evolutionary processes of self-induced fracture formation...

... Abstract Unconventional rock commonly includes sets of natural fractures of different orientation, intensity, and spatial variability. Observation of in situ natural fractures depends on the collection of images logs and core, providing a peek into the subsurface. Predicting natural fractures...

... given by shear deformation of fractures in various orientations with respect to the monitoring well. Three major cases are considered namely, fracture strike is perpendicular to the fiber, the strike is parallel to the fiber, and the fracture strike is at 45 degrees to the fiber. Expected results were...
