A graph of the scaling relationship between fluid flow and fracture stiffness is shown. The shape of the symbol indicates the fracture length scale from 0.0625 meter (circles) to 1 meter (triangle) ...

To gain a deeper understanding of a wide range of geological processes, such as plate tectonics, earthquakes and volcanic diking, we need to have a knowledge of both past and present in situ stress ...

At-a-Glance: Hydraulic fracturing boosts shale well productivity by creating a high-conductivity fracture network that shortens the flow path from nano-Darcy matrix to the wellbore, multiplies ...

WEST LAFAYETTE, Ind. -- A team of researchers has created a way to quickly and remotely evaluate fluid flow in subsurface fractures that could impact aquifers, oil and gas extraction, sequestration of ...

"The units of measurement that describe the different fracture properties span 10 orders of magnitude, which means fluid flow varies by 10 orders of magnitude or more -- fractures are mathematically ...
