Fractures: Flow and geometry

ByL.J. Pyrak-Nolte

An analysis of the interrelationship between fracture specific stiffness and fluid flow through a fracture was performed on data from ten different rock cores each containing a single fracture. The data were from rock cores from different geographic locations and of different sizes and appear to follow the same sigmodial stiffness-fluid flow curve that shows a nine-order-of-magnitude decrease in flow with a three order of magnitude increase in fracture specific stiffness.
