Fracture attributes in reservoir-scale carbonate fault damage zones and implications for damage zone width and growth in the deep subsurface

Journal of Structural Geology, 2019
The width of reservoir-scale fault damage zone governs fluid flow of the tight reservoirs in subsurface petroliferous basins. Together with cores, thin sections, geophysical well logs, and production data from more than 60 wells, we describe fracture ...

A gradient-damage theory for fracture of quasi-brittle materials

Journal of the mechanics and physics of solids, 2019
We present a gradient-damage theory for fracture of “quasi-brittle” materials under tensile dominated stress states. We develop our theory using the method of virtual-power.
