Abstract

A tight sandstone was fractured in a triaxial stress cell by injecting fraccing fluid. The specimen was then scanned with a micro-computed tomograph. From the resulting three-dimensional images the fracture morphology and orientation could be determined. Such measurements can be supportive in the development and validation of fracture propagation models. Such models can help optimizing gas and/or oil production from shales, tight sands, carbonates and coal beds.
