Capturing dynamic behavior of propped and unpropped fractures during flowback and early-time production of shale gas wells using a novel flow-geomechanics coupled model

Pin Jia et al.

Summary: This paper proposes a coupled flow and geomechanics model to capture the dynamic behavior of key fracture parameters during hydraulic fracturing flowback and early production. Detailed analysis of flow behavior is conducted to explore the changes in fracture aperture and the relationship between fracture parameters and flowback and production data.

Numerical simulation of two-phase heat and mass transfer in fractured reservoirs based on projection-based embedded discrete fracture model (pEDFM)

Xiang Rao et al.

Summary: The paper introduces a newly developed numerical simulation framework pEDFM for mass transfer in fractured reservoirs, focusing on its application in simulating two-phase heat and mass transfer. By demonstrating the framework's capabilities in different fracture types and realistic fractured reservoir scenarios, it shows that pEDFM can provide more accurate and efficient results compared to traditional methods.

A transient two-phase flow model for production prediction of tight gas wells with fracturing fluid-induced formation damage

Yonghui Wu et al.

Summary: This paper presents a semi-analytical model considering formation damage and two-phase flow in hydraulic fracturing of tight formations. The model modifies the triple-porosity model, uses a low permeability fracturing fluid invasion layer, and assumes two-phase flow to capture choking effects. An analytical solution and successive iteration method are used, validated with a commercial numerical simulator. The model shows potential for production prediction and analysis in hydraulically fractured tight gas wells.

Dynamic response and fracture evolution of marble specimens containing rectangular cavities subjected to dynamic loading

Lihai Tan et al.

Summary: The stability of underground rock engineering is significantly affected by cavities, and the dynamic response and fracture evolution of rock mass containing cavities are influenced by dynamic loading. Crack evolution and failure modes are associated with cavity number and layout, and the presence of cavities leads to a decrease in dynamic loading capacity and absorbed energy.

Control of Water-Flowing Fracture Development with Solid Backfill Mining: Designing a Backfill Body Compression Ratio for Water Resources Protection

Yun Zhang et al.

Summary: The development of water-flowing fractures in overlying strata due to movement and deformation from cave mining can lead to interconnected fractures and water resource loss. The use of solid backfill mining (SBM) can help control this development, with a mechanical model established to accurately predict the height of the water-flowing fractured zone. The results were validated through a case study in an experimental coal mine, demonstrating the efficacy of the approach in protecting water resources and improving coal recovery.
