The role of chemistry in fracture pattern development and opportunities to advance interpretations of geological materials
Fracture pattern development has been a challenging area of research in the Earth sciences
for more than 100 years. Much has been learned about the spatial and temporal complexity …

Fractal-geometry techniques in the quantification of complex rock structures: a special view on scaling regimes, inhomogeneity and anisotropy
JH Kruhl - Journal of Structural Geology, 2013 - Elsevier
Fractal-geometry techniques are widely applied to the quantification of complex rock
structures. Important properties of such structures are (i) different scaling behaviour on …

[HTML][HTML] Fracture-pattern growth in the deep, chemically reactive subsurface
Arrays of natural opening-mode fractures show systematic patterns in size and spatial
arrangement. The controls on these factors are enigmatic, but in many cases the depth of …

Outcrops as guides to subsurface natural fractures: Example from the Nikanassin Formation tight-gas sandstone, Grande Cache, Alberta foothills, Canada
Outcrop studies are essential for understanding subsurface fractures, because some key
attributes such as length and height distribution cannot be measured using wellbores …
