Hydraulic fracture propagation in naturally fractured reservoirs: Complex fracture or fracture networks [PDF]
Journal of Natural Gas Science and Engineering, 2019 Understanding the behavior of fluid-driven hydraulic fracture in naturally fractured reservoirs is crucial in the development of geothermal energy and unconventional reservoirs. This study presents a fully-coupled numerical model to investigate hydraulic propagation in naturally fractured reservoirs, along with a comprehensive discussion on field ...

Hybrid phase-field modeling of multi-level concrete gravity dam notched cracks
Fracture and Structural Integrity, 2022 Phase-field models have become a powerful tool to simulate crack propagation. They regularize the fracture discontinuity and smooth the transition between the intact and the damaged regions. Based on the thermodynamic function and a diffusive field, they

Examining the effect of cemented natural fractures on hydraulic fracture propagation in hydrostone block experiments [PDF]
, 2012 textMicro seismic data and coring studies suggest that hydraulic fractures interact heavily with natural fractures creating complex fracture networks in naturally fractured reservoirs such as the Barnett shale, the Eagle Ford shale, and the Marcellus ...

Experimental and modeling study of fluid pressure-driven fractures in Darley Dale sandstone [PDF]
, 2004 We report measurements of acoustic emissions (AE) generated during formation and growth of pressure driven fractures in cylindrical samples of Darley Dale sandstone that were co-axially pre-drilled in order to allow an internal pressure to be applied.

A thermodynamically consistent derivation of a frictional-damage cohesive-zone model with different mode i and mode II fracture energies [PDF]
, 2015 The present paper deals with the derivation of an interface model characterized by macroscopic fracture energies which are different in modes I and II, the macroscopic fracture energy being the total energy dissipated per unit of fracture area.

Buoyancy-driven crack propagation from an over-pressured source [PDF]
, 2005 The propagation of a liquid-filled crack from an over-pressured source into a semi-infinite uniform elastic solid is studied. The fluid is lighter than the solid and propagates due to its buoyancy and to the source over-pressure.

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...
