Semi-Analytical Rate Decline Solutions for a Refractured Horizontal Well Intercepted by Multiple Reorientation Fractures with Fracture Face Damage in an Anisotropic Tight Reservoir

Energies, 2021
Refracturing treatment is an economical way to improve the productivity of poorly or damaged fractured horizontal wells in tight reservoirs. Fracture reorientation and fracture face damage may occur during refracturing treatment.

Fracture through cavitation in a metallic glass [PDF]

, 2008
The fracture surfaces of a Zr-based bulk metallic glass exhibit exotic multi-affine isotropic scaling properties. The study of the mismatch between the two facing fracture surfaces as a function of their distance shows that fracture occurs mostly through

Rock and soil damage-fracture space mechanics: Damage-fracture space [PDF]

Proceedings on Intelligent Systems and Knowledge Engineering (ISKE2007), 2007
Each of the current analytical methods used in rock and soil CT mechanics is “observation”, wasting the precious CT quantitative information. Utilizing the CT number, the perfect degree and the damage-fracture degree of a point inside the rock sample are defined, the λ level perfect field, the λ level damage-fracture field and the λ1-λ2 level ...
