Mechanical stratigraphy encompasses the mechanical properties, thicknesses, and interface
properties of rock units. Although mechanical stratigraphy often relates directly to …

Spatial arrangement is a fundamental characteristic of fracture arrays. The pattern of fault
and opening-mode fracture positions in space defines structural heterogeneity and …

Fine-grained low permeability sedimentary rocks, such as shale and mudrock, have drawn
attention as unconventional hydrocarbon reservoirs. Fracturing–both natural and induced–is …

We present new techniques that overcome limitations of standard approaches to
documenting spatial arrangement. The new techniques directly quantify spatial arrangement …

Through-going joints cutting across beds are often invoked to match large-scale
permeability patterns in tight carbonate reservoirs. However, despite the importance of these …

Faults have complicated shapes. Non-planarity of faults can be caused by variations in
failure modes, which in turn are dictated by mechanical stratigraphy interacting with the …

Abstract The Upper Cretaceous Frontier Formation is a naturally fractured gas-producing
sandstone in Wyoming. Regionally, random and statistically more clustered than random …

We demonstrate statistically significant self-organized clustering over a length scale range
from 10− 2 to 101 m for north-striking opening-mode fractures (joints) in Late Archean Mount …

A 1.5 km long natural cliff outcrop of nearly horizontal Eagle Ford Formation in south Texas
exposes northwest and southeast dipping normal faults with displacements of 0.01–7 m …

Abstract Production from the Ekofisk Chalk Field in the North Sea is believed to be
significantly influenced by the presence of a connected fault and fracture network. In the …
