Study on the cracking mechanism of hydraulic and supercritical CO2 fracturing in hot dry rock under thermal stress

, 2021
To realize the effective extraction of high-temperature thermal energy in enhanced geothermal system (EGS), it is necessary to explore how to efficiently construct fracture network in hot dry rock (HDR).

Exploring the influence of heterogeneity on hydraulic fracturing based on the combined finite–discrete method

Engineering Fracture Mechanics, 2021
Hydraulic fracture propagation is known to be influenced by heterogeneity; therefore, the influence of different heterogeneity characteristics on the propagation must be studied.

Peridynamics simulation of hydraulic fracturing in three-dimensional fractured rock mass

The Physics of Fluids
Fissures in rock masses offer sites for groundwater seepage and weaken the mechanical properties of rocks to a certain extent. Moreover, seepage water pressure exerts a direct influence on engineering construction and may even trigger engineering ...

A three-dimensional numerical study of hydraulic fracturing with degradable diverting materials via CZM-based FEM

, 2020
Both microseismic interpretation and post-frac production analysis have confirmed that initial hydrocarbon production and ultimate recovery in reservoirs are mainly associated with the degree of fracture complexity.

Influences of hydraulic fracturing on microfractures of high-rank coal under different in-situ stress conditions

, 2020
The influence of hydraulic fracturing on coal microfractures (10–1000 μm) is an important part of the stimulation mechanism of coalbed methane (CBM) hydraulic fracturing, which is of great significance to improve the productivity of CBM.
