..., the image log indicated that the well was drilled through numerous, sub-seismic folds. Near the toe of the lateral, three distinct intervals separated by ∼30-40 feet were identified: (a) normal bedding (less-folded), (b) the presence of a fold structure, and (c) presence of a fold structure with fractures...

... Abstract The fine-scale lamination/bedding is an important feature commonly neglected in the characterization of unconventional reservoirs. Self-sourced mudstone deposits are frequently described as layered, or Vertical Transverse Isotropic (VTI) bodies, assuming the absence of significant...

... ratio and maximum dip angle relative to bedding. Our modeling results confirm that the compliance ratio is sensitive to fluid. Fluid-saturated rocks exhibit a lower compliance ratio than that of dry rocks, which is usually less than 1 and close to 0. This behavior is consistent with a fluid stiffening...

We also evaluate some industry-recognized factors affecting the fracture propagation such as vertical stress differences or weak planes induced fracture containment, fluid viscosity, natural fractures, horizontal beddings, horizontal stress...

... models may be more compliant. Normal compliance calculated from the static data confirms that propped models are more compliant. We extend this experiment with Eagle Ford Shale samples, we find that S-wave velocity is faster in propped rock in all directions (0 0 , 45 0 , 90 0 to the bedding). We also...

We found that samples sheared parallel to bedding were less likely to develop extensive networks of secondary fractures, with secondary fracture growth contingent on the presence of large asperities. Fracture permeability tended to increase with continued shear and secondary fracture development...
