The characterization of artificial fracture propagation law in the fracturing process of shale
reservoirs is the basis for evaluating the fracture conductivity and a key indicator of the …

Hydraulic fracturing is an effective method to improve the permeability of coal seams and
enhance extraction of coalbed methane (CBM). Evolution of cracks in coal seam becomes …

Deep shale gas reservoirs, compared to shallow and intermediate shale gas reservoirs,
usually exhibit lower fracture complexity, smaller stimulated volume, poorer conductivity, and …

Complex fracture networks have been observed in mine-back experiments, core samples,
and other fracture diagnostic measurements. The interaction between hydraulic and natural …

Natural geomaterials often exhibit pore size distributions with two dominant porosity scales.
Examples include fractured rocks where the dominant porosities are those of the fractures …

In this study, a new coupled fluid flow and fracture phase field evolution model is proposed
to simulate hydraulic fracture propagation in porous media with natural fracture. In the …

Multi-cluster fracturing in horizontal wells is a key technology for successful development of
ultra-low permeability reservoir. The propagation of hydraulic fracture during multi-cluster …

Hydraulic fracturing is commonly used to enhance the hydraulic conductivity of geothermal,
oil, and gas reservoirs, particularly those situated in enclosed and unconventional …

Hydraulic fracturing is the main technology for the development of unconventional
resources. The key factor affecting the formation of the fracture network in hydraulic …

In this paper, a comprehensive model combining analytical and numerical solution has been
developed to study the interaction between a hydraulic fracture (HF) and a natural fracture …
