Fracture propagation laws in staged hydraulic fracturing and their effects on fracture conductivities

Petroleum Exploration and Development, 2017
Completely taking into account the interferences between fractures as well as the friction effects on injection allocations, a fully coupled finite element method inherited from a verified one is proposed to discuss fracture propagation laws and analyze their impacts on fracture conductivities.

Performance of vertical fractured wells with multiple finite-conductivity fractures [PDF]

Journal of Geophysics and Engineering, 2015
Multiple fractures originating from a vertical wellbore are usually observed in hydraulic fracturing treatments. Most of the previous models for vertical fractured wells are based on single-planar fractures that may be symmetric or asymmetric about the wellbore, but few studies have been devoted to multiple-planar fractures.

Simulating infiltration processes into fractured and swelling soils as triggering factors of landslides [PDF]

, 2013
The influence of rainfall in triggering landslides is a widely discussed topic in scientific literature. The slope stability of fractured surface soils is often influenced by the soil suction.

Avalanches in Breakdown and Fracture Processes

, 1999
We investigate the breakdown of disordered networks under the action of an increasing external---mechanical or electrical---force. We perform a mean-field analysis and estimate scaling exponents for the approach to the instability.
