Multiple three-dimensional non-planar fractures are seen to grow and interact within each region. The simulated patterns...

... fracturing can produce a complex initial fracturing pattern via very high dynamic pressures which tend to ignore the local stress state conditions (Cuderman, 1981) but is essentially a single pulse technology that requires the fracturing tool to be removed, reloaded at the surface and re-inserted to apply...

...1. INTRODUCTION The growth of multiple interacting fractures is instrumental in understanding how fracture patterns evolve across scales, and how fracture geometry and topology evolves within a group during mixed mode loading. In particular, realistic modeling of hydraulic fracturing is of great...

... ABSTRACT: Fracture patterns experienced under a dynamic uniaxial compressive load are highly sensitive to rock microstructural defects due to its brittleness and the absence of macroscopic stress concentration points. We propose two different approaches for modeling rock microstructural...

... ABSTRACT: Hydraulic fracturing has been the most common approach to stimulate tight formations. The geometry of the wellbore and the time history of the hydraulic loading play important roles in induced fracture patterns. For example, generating multiple perforations in a wellbore is nowadays...
