Improvement of rock surface roughness accuracy by combining object space resolution error and 3D point cloud features

Frontiers in Earth Science
To enhance the accuracy of joint roughness coefficient (JRC) estimation in photogrammetry, this study employed a fixed-camera shooting strategy guided by a Structure-from-Motion-based shooting parameter selection algorithm to reconstruct 3D models of ...

Shear Behavior of Two-Dimensional Propped Rough Fractures

Energies
The deployment of proppant to fracture shear is a promising approach to stimulating hydraulic permeability in fractured reservoirs. However, the interactive effects of proppant and surface roughness have not been clearly revealed.
