Multi-scale characterization of porosity in naturally mineralized fractures
Naturally occurring fracture systems contain a separate porosity and permeability that can impact the way fluid flow through a rock by either providing flow obstruction or avenues of preferential flow. Current techniques for quantifying fracture porosity and permeability are limited to length scales of 10’s to 100’s of microns up to millimeter resolution, yet we know that pore networks in rock are fractal systems with porosity in the micron to manometer length scales. Because nano-scale pores play an important role in tight rock matrices, it is possible that pores at these length scales in natural ...
