Variational Principles for Hydraulic Fracturing
Journal of Applied Mechanics, 1992A new application of an energy rate variational principle for hydraulic fracturing processes is introduced. The formation structural, fracture mechanics, and fracture fluid flow responses are integrally coupled in this treatment. This unified principle, with various specialized forms, provides a formal framework for the study of continuum as well as ...

Influence of gravel on the propagation pattern of hydraulic fracture in the glutenite reservoir
Journal of Petroleum Science and Engineering, 2018The clear mechanism of hydraulic fracture propagation in glutenite reservoirs with high heterogeneity is still not obtained, thus it is difficult to carry out the design of fracturing plan effectively.

Fracture toughness and hydraulic fracturing
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1989Abstract A study of the influence of fracture toughness on the shape of a hydraulically induced fracture is presented. Three-dimensional numerical simulations of fracture propagation show that fracture toughness is not the main controlling parameter if one chooses fracture toughness values determined at ambient conditions.
