Compared to simultaneous fracturing scheme, study results show that zipper fracturing scheme has a better performance in promoting the fracture complexity and increasing the fracture surface area, which is favorable to enhance hydrocarbon production.
Then, case studies are performed to investigate the influences of fracture spacing, well spacing and fracturing scheme on fracture growths in multi-well fracturing.
Complex monitoring of the fracture process together with loading traces enables to characterise typical fracture features and crack propagation schemes.
Water-sealing performances of different water curtain system schemes with various fracture networks are also discussed.
This, in turn, allows the inclusion of a significant larger number of geological fractures into the model and the implementation of probabilistic block analyses schemes for a large number of stochastic fractures in a model.
Conventional Dual-Porosity Dual-Permeability (DPDP) schemes are not adequate to model such complex fracture-network systems.
In the quasi-brittle failure regime, good agreement was found between the fracture toughness values determined by force based and dynamic data reduction schemes.
Because different types of odontoid fracture are not included in the current Abbreviated Injury Scale, appropriate coding schemes should be developed to classify this injury.
The E.U. should not risk fracturing the relationship with the U.S., as doing so is nothing less than foolish in the grand scheme of things, especially given the challenges facing the continent. .
The classification scheme of odontoid fractures described by Anderson and D'Alonzo is the one most commonly used.
