An experimental study of hydraulic fracture and erosion
… thesis concerns an experimental investigation of hydraulic fracturing when the water pressure is increased rapidly in a borehole and development of a possible simple method for identifying erodible clayey soils. Case histories of hydraulic fracturing in embankment dams and boreholes are reviewed. …

Fracture and hydraulic fracture initiation, propagation and coalescence in shale
Even though hydraulic fracturing has been in use for more than six decades to extract oil and natural gas, the fundamental mechanism to initiate and propagate these fractures remains unclear. Moreover, it is unknown how the propagating fracture interacts with other fractures in the Earth. The …

An integrated peridynamics-finite volume based multi-phase flow, geomechanics and hydraulic fracture model
Hydraulic fracturing in unconventional reservoirs exhibits several interesting phenomena including the interaction of hydraulic fractures with multi-scale heterogeneities such as natural fractures, stress/barrier layers, bedding planes, shale laminations, and mineralogy. Moreover, hydraulic …

Solving three-dimensional problems in natural and hydraulic fracture development : insight from displacement discontinuity modeling
Although many fracture models are based on two-dimensional plane strain approximations, accurately predicting fracture propagation geometry requires accounting for the three-dimensional aspects of fractures. In this study, we implemented 3-D displacement discontinuity (DD) boundary element modeling …

A generalized finite element method for the simulation of non-planar three-dimensional hydraulic fracture propagation
Hydraulic fractures are a class of tensile fractures that occur in brittle and quasi-brittle materials due to the injection of a viscous fluid. Hydraulic fractures occur both naturally and created deliberately for engineering applications. In the oil and gas industry, it is a preferred method to …

Correlstion between the volume of slurry and the volume of fracture in Barnett Shale
Microseismic fracture mapping has revealed that large fracture networks can be generated in many shale reservoirs and create multiple of plan complex structure. The ultra-low permeability in Barnett shale requires hydraulic fracturing to generate wellbore contact with the reservoir in order to …

Some rock mechanics problems with application for hydraulic fracturing
Hydraulic fracturing is an essential tool used to enhance connectivity in shale gas reservoirs by maximizing the intersection between the hydraulic fracture (HF) and pre-existing natural fractures (NF) or faults. The technique is most effective when the hydraulic fracture crosses natural fractures …
