Furthermore, with increasing number of natural fractures, initial fracture pressure decreases and the initiation mode tends to be tensile failure along natural fracture plane.
However, in fractured formation, it is very tricky to obtain initial fracture pressure due to the influence of rich natural fractures.
Three weeks later (after more tests), the Nets revealed that Lopez's initial fracture had not fully healed.
The pencil-sized threshold opening marks the boundary between the initial fracture system and the evolving conduit system.
Initial fracture aperture, mm.
B Initial fracture propagation.
This allowed initial fracture stabilization.
Therefore, the initial fracture haematoma and its surrounding tissues evolve and develop in tight interplay.
The model has been used to investigate influence factors of initial fracture pressure.
Abrasion or chemical etching is employed on the coating surfaces to control the initial fracture.
Our research focuses on well-connected fracture networks, so we employ percolation theory here to analyze the connectivity of the initial fracture network, to illustrate how far above percolation threshold, and how well connected, the initial fracture network is.
