Conventional discrete fracture network (DFN) modeling is used to simulate hydraulic fracture
propagation in fractured low permeability reservoirs. However, natural fractures have a …

A systematic hybrid approach for modelling the hydraulic fracturing process of
heterogeneous rocks with irregular inclusions is developed. This approach is based on a …

Rough surfaces exist widely in nature, and the measurement of these surfaces' fractal
dimension is beneficial for understanding their formation mechanism and effect. The basic …

Hydraulic fracturing operation as an effective enhancing coalbed gas production method is
widely used in ultra-low permeability coal seam. However, complex geo-stresses and high …

Hydraulic fracturing has proven to be an efficient technique to enhance production in
unconventional reservoirs. Since heterogeneity is commonplace in reservoir rocks, it is vital …

In this paper, a novel coupling explicit phase-field material point method with the convected
particle domain interpolation (ePF-CCPDI) is proposed to predict the large deformation …

Highly efficient stimulating fracture network is crucial for the utilization and operation of
enhanced geothermal systems, in which involved heat transfer and fluid flow process highly …

Hydraulic fracturing is one of the key technologies of shale gas extraction. Deeply
comprehending the distribution characteristics of hydraulic fracture networks in shale …

As a critical technology for the efficient exploitation of shale gas, hydraulic fracturing is a two-
way fluid-solid coupling interaction process of water-rock. The accurate water pressure …

Hydraulic fracture propagation is known to be influenced by heterogeneity; therefore, the
influence of different heterogeneity characteristics on the propagation must be studied …
